An oasis is a kind of medium-sized or small-sized non-zonal landscape coming into being in the dry climate and supported by natural rivers in deserts, which is characterized by the comparatively high primary pro- ductivity and has the mesophytic plants or xero-mesophytic plants as the dominant vegetation (Jia, 1996). The oasis system, first of all, is a subsystem within the macro system of “mountain-oasis-desert” in the arid region. It is also a complex system where the natural and artificia… 相似文献

Using the data at the county levcl and the regional gravity center model, we calculated six key socio-economic gravity centers, namely population, GDP, output values of primary, secondary and tertiary industries, and arable land area in the Tarim River Basin for each year from 1980 to 2009. We inspected the spatial dynamics of these centers and found that the gravity centers of population and economy evolved simultaneously. The disproportional growth between the population and the economy is also analyzed. The results show that： 1） The gravity centers of the GDR the output values of the main three industries and arable land area show migration trending from southwest to northeast, while the population gravity center shows an excessive growth in the southwest during the same time period. The migration amplitude of the GDP and output values of primary industry, secondary industry, tertiary industry are measurably higher than that of the population. 2） The population gravity center has a negative correlation with the gravity centers of secondary and tertiary industries output values in both longitudinal and latitudinal directions, and a positive correlation with that of primary industry output value in the longitudinal direction. Based on the analysis of correlation coefficient and offset distance, the imbalance between the population and the economy has increased since the 1980s, with regional economic differences now exceeding the international cordon. 相似文献

Spatial effect of mineral resources exploitation on urbanization: A case study of Tarim River Basin, Xinjiang, China 总被引：1，自引：0，他引：1
Mineral resources exploitation significantly affects the spatial structure and evolutive trend of urbanization in arid areas.In this study,the spatial autocorrelation method and the spatial computation model were used to investigate the spatial impacts of mineral resources excavation and processing on comprehensive level of urbanization in the Tarim River Basin,Xinjiang,China for the years of 2000,2006 and 2008.The results are as follows:1)There was a spatial correlation of the development of mineral resources industry and the comprehensive level of urbanization in 2006 and 2008,with the spatial concentration trend rising significantly in 2006 and decreasing in 2008.2)The patterns of local spatial concentration of mineral resources industry and of the comprehensive level of urbanization were relatively stable,and the two patterns showed signs of spatial correlationship.The higher was the degree of the concentration of mineral resources industry,the stronger was its impact on the spatial clustering of urbanization.3)In 2000, mineral resources excavation and processing had a significant positive impact on the comprehensive level of urbanization in the region but not in its adjacent regions.However,in 2008,mineral resources excavation and processing significantly raised the comprehensive level of urbanization not only in the region but also in its neighboring regions.This research demonstrates that the development of mineral resources industry can strongly affect the trends and spatial patterns of urbanization. 相似文献

This paper summarizes the distribution and production layout of the major mineral resources in China,including coal,iron ore,copper and bauxite,from a national perspective.It also identifies the incompatibility between the mineral resources distribution and regional economic development.Significant issues with China’s mineral resource industry cause challenges for the sustainable development of both the mining industry and the national socio-economy.The sustainability of regional mineral resources and the environmental pollution by mining in the western China were also analyzed.Results show that the distribution of China’s mineral resources is misaligned with its regional layout of economic development.China’s mineral resources have been over-exploited,and the mineral resources production in the eastern China is unsustainable.The continuously expanding production of mineral resources in the western China has heavily endangered the ecological environment.We propose strategies to boost the sustainable development of mineral resources,including measures to accelerate economic development and enhance the sustainability of domestic mineral resources.We also offer suggestions for scientifically planning the mineral resource prospecting and exploitation and regional economic layout,as well as for proactively undertaking industry transfer in the eastern China and raising the environmental benchmark requirements for the mineral industry in the central and western China. 相似文献

On the basis of the study on areal differentiation of the natural environment of oasis agriculture ecosystems in the Shiyang River Basin, this paper comparatively analyzes the natural productivities, water economic benefits, production efficiency, ecological stabilities and developmental conditions of the Wuwei Oasis agricultural ecosystem in the middle reaches of the river basin and the Minqin Oasis agricultural ecosystem in the lower reaches. Under a same management level and investment of . material and energy, primary productiveness and economic benefits of the former are higher than those of the latter. Construction directions of Wuwei and Minqin oases should be different in order to alleviate the water- use contradiction between the middle and lower reaches. The construction objective of Wuwei Oasis should be efficient irrigated farming production system and Minqin Oasis should become a mixed forestry-pastoral-farming ecosystem taking ecological protection as its major function. 相似文献

黑河流域地处西北干旱区,水资源短缺是限制其中游绿洲农业发展、下游生态环境保护的首要原因。该流域的中游绿洲农业用水约占总用水量的80%,因此农业节水对流域发展至关重要。在干旱区绿洲农业节水探索中,众多学者主张通过节水技术来提高用水效率,而关于农业种植结构调整对农业节水影响的定量研究较少。本文采用2012年黑河流域蒸散发数据、土地利用数据、降水数据和农业经济统计数据,定量分析黑河中游主要作物需水特征和用水效率差异,尝试从调整作物种植结构角度为其绿洲农业节水提供依据。结果表明：(1)研究区4种主要作物中,玉米生长期需水量最大,其次为小麦、油菜和大麦;(2)考虑降水补给,发现大麦和油菜生长需水可很大程度上依赖降水,而小麦和玉米则需要灌溉,且玉米灌溉需水量远超小麦;(3)作物用水效率由高到低依次为大麦、油菜、小麦和玉米。从用水效率角度而言,考虑种植区位,在黑河中游适当扩大小麦种植规模更有利于提高中游农业用水效率。 相似文献

The economic system of mining city is of typical vulnerability characteristics that can be manifested by its high economic
sensitivity and lack of response capacity to the gradual depletion of regional mineral resources. Taking Fuxin City of Liaoning
Province as a case, this paper established an economic vulnerability assessment method integrating BP neural network with
vulnerability index, then carried out an economic vulnerability assessment of Fuxin during 1989–2006. The results indicate
that: 1) Affected by the gradual depletion of regional mineral resources, the economic development of Fuxin had kept high
economic sensitivity from 1995 to 2001, and the response capacity to cope with and adapt to the impacts of the perturbation
of mineral resources was weak and relatively lag. The evolution of economic vulnerability can be divided into three stages:
in 1989–1994, the economic vulnerability of Fuxin City decreased slowly; in 1995–2001, the beginning stage of economic transformation,
the economic vulnerability of Fuxin City went up rapidly; in 2002–2006, the economic vulnerability of Fuxin City descended
and showed a trend to be stable. 2) The influence of economic sensitivity on Fuxin’s economic vulnerability is more evident
than that of response capacity. 3) The decreasing supply of mineral resources and the simple industrial structure are main
factors leading to the economic sensitivity of Fuxin. 4) The improvement of economic response capacity of Fuxin has typical
characteristics of input-driven growth, and external assistance is of great importance to the rapid improvement of economic
response capacity of Fuxin. And 5) the change from the simple industrial structure to diversified one of Fuxin is still unaccomplished,
and the contribution of non-coal-based industry to local economic development is relatively limited.

It is great important to the health development of urban agglomeration to correctly understand the formation and development
law of regional structure of urban agglomeration. Employing the analysis methods like fractal theory and quantitative statistics,
coupling with the use of remote sensing images and other spatial data, this article discusses the urban agglomeration of oasis
on the northern slope of the Tianshan Mountains in an arid area, and conducts the researches on its city scale, spatial distribution
and individual form from 1990 to 2005. The result shows that it has loose hierarchical scale structure and polarization trend
of population distribution while its hierarchical scale structure tends to mature. Under the influence of natural conditions,
the spatial layout of urban agglomeration of oasis has macro characteristics that suggest cities distributed along oasis edges
(dense or sparse), spatially expand along rivers, and cluster around traffic branches. The connectivity among the cities is
high and shows an internal organization form of a banding distribution. The whole spatial shape of the internal structure
of cities presents a “dumbbell” form, with mononuclear phenomenon receding and multi-nuclear appearing gradually. Individual
cities spatially expand along rivers, portraying a long strip appearance. It indicates that the urban agglomeration of oasis
shows regular and close structure but with a tendency to be complicated form and the loose structure. In the development of
urban agglomeration, the authors recommend that the development of the city with good economic development conditions should
be strengthened, and more attention be put into regional planning. 相似文献

The spatial agglomeration of agricultural production is conducive to reducing planting costs, increasing production efficiency and improving product quality. It is an important way to promote the transformation and upgrad of tea industry and realize the modernization of China’s tea industry. This study used Gini coefficient and spatial autocorrelation analysis to explore the characteristics of tea spatial agglomeration in China from three geographical scales: regional level, provincial level and prefecture level from the year 2005 to 2015. The results indicated that there was a significant scale effect on the tea spatial agglomeration. The agglomeration degree increased from the regional level, provincial level to prefecture level. The types of spatial agglomeration evolution of the three scales were Ushaped, continuous diffusion, and continuous agglomeration. The spatial autocorrelation of tea production could only be found at the prefecture level. Meanwhile, at the prefecture scale, we could not only reveal the pattern changes at the regional and provincial levels, but also identify tea production agglomeration regions. Compared with the large scale, the small scale could reveal the characteristics of tea spatial agglomeration in more details. Factors such as natural resource endowments, cost factor, technological advancement, agglomeration economy, and agricultural policy influenced the evolution of tea spatial agglomeration from different geographical scales. Finally, from the perspectives of spatial transfer of tea production, promoting spatial agglomeration, building tea production bases, and breaking administrative boundaries, we proposed several policy suggestions for optimizing the spatial layout of tea production. 相似文献

In the knowledge economy era,science and technology(S&T) resources are getting more and more important in shaping regional competiveness and building regional innovation capacity.As such,the spatial distribution of S&T resources is a key to understanding regional development and disparities.By designing an input-output indicator system,this paper develops an evaluation model to examine the spatial distribution of S&T resources in China and assess their spatial efficiency.Moreover,the paper tries to explain spatial differences in the efficiency of S&T resources in China.Major findings are:1) the input and output of S&T resources in China shows a clear T-shaped spatial structure,i.e.,concentrated mainly in the coastal region and along the Changjiang(Yangtze) River;2) the efficiency of S&T resources in China displays strong spatial disparities,with the level of efficiency descending from the east to the west while high efficiency appearing in only several clusters;3) the utilization rates of S&T resources in most provinces are quite low,resulting in low efficiency of S&T resources allocation.The paper suggests that the utilization rate of S&T resources should be raised and the commercialization of S&T outputs should be enhanced to improve the efficiency of S&T resources in China. 相似文献

Based on data of questionnaire and field survey and two developing models of Business As Usual (BAU) and the Intensive Urbanization
(IU), this article, taking Wuwei City, a medium size city and typical oasis arid area in Gansu Province with very vulnerable
and sensitive natural environment but long history of oasis economy, as an example, evaluated the sustainability of its environment
and analyzed the scenarios of Wuwei’s household energy consumption, waste discharge in transportation industry, primary industry,
secondary industry, tertiary industry, by the integration of the systematical dynamics model Stella and Polestar language
to simulate the future development of the research area. The results showed that, first, the developing model of IU was propitious
to Wuwei City named for oasis economy and vulnerable natural environment. The strategy of "Intensive Urbanization" can change
the structure of energy utilization, and improve the efficiency of energy utilization. Second, the proportion of domestic
energy consumption will decrease with industrialization and economic development, while that of tertiary industry, secondary
industry and transportation will gradually grow up according to strategy of "Intensive Urbanization". Third, the Wuwei City
is facing a severe eco-environmental crisis under the conventional patterns of development and a better future under a sustainable
urbanization scenario, in the next 10 to 20 years. The different developing trends were clarified and the relative countermeasures
were put forward for the policy makers according to the driving forces.
