The aim of this study is to evaluate the current state of rural area development at the county level in the eastern coastal China. An evaluation index system including 18 factors was developed, and a rural development index (RDI) was constructed to evaluate rural development state in 2000, 2004, and 2008. The quantitative evaluation indicated the following results. 1) This study derived four dominating components by means of principal component analysis, which can explain 78.2% of the total information, namely agricultural production input, the basic condition of agriculture, the comparative effectiveness of grain production, and the household′s own basic conditions. 2) Since the turn of the new millennium, the rural area in the eastern coastal China has experienced a rapid development in general. Well developed, developed, moderately developed and undeveloped rural areas respectively occupied 29.32%, 22.33%, 21.91%, and 10.51% in 2008. 3) The countryside had maintained a sound momentum of developing trend between 2000 and 2008, while the rural development in the eastern coastal China lacked sustainability. And 4) industrialization, urbanization, original economic basis, and location are four major driving forces of the disparity of rural area development in the eastern coastal China. Given these results, the strategies and policies for the improvement of each rural group were put forward. 相似文献

1 INTRODUCTIONChina′s reform and open policies commenced in 1978 have developed international economic linkages and brought the country on the track toward economic globalization. Large amount of foreign direct investment (FDI) has flown to China and China has become the second or third largest FDI recipient since 1993 (UNCTAD, 1996; 1999). The annual increase in foreign trade has doubled the GDP growth rates. The globalization process has been accelerated since the mid-1990s as… 相似文献

China is a large marine country. Developing marine economy is an effective way to solve a series of problems with which man is faced, such as the want of natural resources, space limitation, the environmental deterioration, etc. This article analyzes the rich resources of marine biology, harbor, offshore oil and natural gas and coastal tourism resources in China and describes the developing features and regional differences of marine economy. To realize the sustainable development of marine economy in China, what we need to do are as follows: 1 ) to list exploiting ocean into national development strategy; 2) to realize integrated economy of sea and land; 3) to develop ocean by science and technology; 4) to perfect legal institution of marine environment; 5) to establish new idea of sea defending. 相似文献

基于多源数据的中国海岸带地区人口空间化模拟 总被引：1，自引：0，他引：1
海岸带人口聚集、经济增长迅速、生态环境脆弱,容易受到自然灾害的影响,细致的人口空间分布信息对解决海岸带地区资源配置、灾害风险管理等有重要意义。本文以中国沿海城市为研究区,基于NPP-VIIRS和NDVI数据构建人居指数HSI,并加入居住地面积比例系数反映人口内部差异,利用样本动态分区及建模方法,得到2015年中国海岸带1000 m格网人口分布数据（POP）,并将其与已公布的相同年份的中国公里格网人口数据（TPOP）和100 m全球人口数据（WorldPOP）进行对比分析。研究表明,3种数据均能反映中国海岸带地区人口的宏观分布特征,但是对于人口分布城乡差异特征以及城市内部人口分布细节特征的刻画,则是以POP数据最为理想。由县域统计值和POP数据可知,主要受沿海地貌、国家及区域经济发展战略等的影响,中国海岸带地区人口分布具有明显的空间差异,具体来说：① 地形差异,山地和滩涂区域的人口密度普遍较低（小于5 人/hm 2）,而平原和河口三角洲区域的人口密度则普遍较高（大于10 人/hm 2）;② 宏观区域差异,环渤海、长江三角洲和珠江三角洲是人口分布最密集的区域（大于25 人/hm 2）;长江以北地区人口分布多层级重心离散分布的特征较为显著,尤其以山东和江苏最为明显,长江以南地区人口分布相对比较集中,主要集中在沿海低地和平原,如浙江—福建—广东一带;③ 城乡差异,由各级城镇向乡村区域递减的趋势非常明显,城市等级越高,人口分布的梯度特征越显著,中心城区、城市近郊、城市远郊之间相比人口密度差异巨大。 相似文献

Based on the field data obtained during cruises on the shelf of the East China Sea from 1997 to 1999, seasonal variations of coastal upwelling on the inner shelf are discussed by using cross-shelf transect profiles and horizontal distributions of chemical and hydrographic variables. Results show that the coastal upwelling was year-round, but the areas and intensities of the upwelling were quite different in season. The coastal upwelling occurred in all of the coastal areas of the region in spring and summer, but in autumn only in the area off Zhejiang Province, and in winter in the area off Fujian Prov- ince. It was the strongest in summer and the weakest in winter. Geographically, it was the strongest in the area off Zhejiang Province and the weakest in the southmost or northmost parts of the East China Sea. The estimated nutrient fluxes upward into euphotic zone through coastal upwelling were quite large, es- pecially for phosphate, which contributed significantly to primary production and improved the nutrient structure of the coastal ecosystem in the East China Sea. 相似文献

Denitrification and anammox processes are major nitrogen removal processes in coastal ecosystems.However,the spatiotemporal dynamics and driving factors of the diversity and community structure of involved functional bacteria have not been well illustrated in coastal environments,especially in human-dominated ecosystems.In this study,we investigated the distributions of denitrifiers and anammox bacteria in the eutrophic Bohai Sea and the northern Yellow Sea of China in May and November of2012 by constructing clone libraries employing nosZ and 16 S rRNA gene biomarkers.The diversity of nosZ-denitrifier was much higher at the coastal sites compared with the central sites,but not significant among basins or seasons.Alphaproteobacteria were predominant and prevalent in the sediments,whereas Betaproteobacteria primarily occurred at the site near the Huanghe(Yellow)River estuary.Anammox bacteria Candidatus Scalindua was predominant in the sediments,and besides,Candidatus Brocadia and Candidatus Kuenenia were also detected at the site near the Huanghe River estuary that received strong riverine and anthropogenic impacts.Salinity was the most important in structuring communities of nosZdenitrifier and anammox bacteria.Additionally,anthropogenic perturbations(e.g.nitrogen overloading and consequent high primary productivity,and heavy metal discharges)contributed significantly to shaping community structures of denitrifier and anammox bacteria,suggesting that anthropogenic activities would influence and even change the ecological function of coastal ecosystems. 相似文献

Based on the in situ optical measurements in the Bohai Sea of China, which belongs to a typical case-2 water area, we studied the characteristics of DCM （deep chlorophyll maximum） such as its spatial distribution, vertical profile, etc. We found that when the depth of the chlorophyll maximum is comparatively small, even in turbid coastal water regions, there is always a good correlation between the concentrations of chlorophyll maximum and the satellite-received signals in blue-green spectral bands; the correlation is even better than that between the surface chlorophyll concentrations and the satellite-received signals. The strong correlation existing even in turbid coastal water regions indicates that an ocean color model to retrieve the concentration of DCM can be constructed for coastal waters if a comprehensive knowledge of the vertical distribution of chlorophyll concentration in the Bohai Sea of China is available. 相似文献

Field measurements of influence of sand transport rate on structure of wind-sand flow over coastal transverse ridge 总被引：2，自引：0，他引：2
The structure of wind-sand flow under different total sand transport rates was measured with field vertical anemometer and sand trap on the crest of typical coastal transverse ridge in Changli Gold Coast of Hebei Province, which is one of the most typical coastal aeolian distribution regions in China and famous for the tall and typical coastal transverse ridges. The measurement results show that, on the conditions of approximate wind velocities and same surface materials and environments, some changes happen to the structure of wind-sand flow with the increase of total sand transport rate on the crest of coastal transverse ridge. First, the sand transport rates of layers at different heights in the wind-sand flow increase, with the maximum increase at the height layer of 4-8cm. Second, the ratios of sand transport rates of layers at different heights to total sand transport rate decrease at the low height layer （0-4cm）, but increase at the high height layer （4-60cm）. Third, the distribution of the sand transport rate in the wind-sand flow can be expressed by an exponential function at the height layer of 0-40cm, but it changes from power function model to exponential function model in the whole height layer （0-60cm） and changes into polynomial function model at the height layer of 40-60cm with the increase of total sand transport rate. Those changes have a close relationship with the limit of sand grain size of wind flow transporting and composition of sand grain size in the wind-sand flow. 相似文献

In this study, a simple method for the simultaneous determination of trace metals(Cu, V, Co, Zn) in coastal seawater using the Mg(OH)2 coprecipitation inductively coupled plasma mass spectrometry(ICP-MS) was developed. This multi-element method enables the simultaneous extraction of four metals, particularly Co and V. The recoveries of Cu, Co, V and Zn after Mg(OH)2 coprecipitation were 73%, 96%, 94% and 92%, which means that our procedure was well-suited to the determination of these four trace metals. The detection limits were 3.81, 0.18, 6.09 and 1.91 nmol L-1, respectively. Then, applying this method to the simultaneous determination of these four metals in coastal water samples from the East China Sea revealed that the concentrations of Cu, Zn, Co and V were higher in bottom waters compared to water at other depths, and higher concentrations were generally observed at the Yangtze River estuary. Additionally, example vertical profiles of dissolved trace metal concentrations for the East China Sea in spring and autumn are compared. These findings indicate that Zn had the greatest seasonal variation followed by Cu, V and Co. For Zn and Co, the concentrations were higher during spring than during autumn. For Cu and V, the seasonal variation in the concentrations was opposite. 相似文献

ESTUARINE AND COASTAL CHALLENGES IN CHINA 总被引：9，自引：0，他引：9
Estuaries and coasts axe conjunctions of four spheres (atmosphere, lithosphere, hydrosphere and biosphere) and important matter and energy convergence/divergence zones, where devel-oped economy, dense population and highly intensive exploitation induce adverse environmental changes and serious destruction of resources, which have great impacts on coastal sustainable development, espe-cially as the highly intensive development in river basins has direct and pronounced effects on estuaries and their adjacent coasts. In the new century, China‘s estuaries and coast are faced with four main chal-lenges : sharp decrease of sediment discharge into the sea, rapid increase of pollution matter into the sea, loss of coastal wetland, and the impacts of global sea level rise on the coastal lowlands of China. There-fore, it is undoubtedly very important and urgent to carry out studies on estuarine and coastal environmen-tal changes, in order to resolve the issue of national sustainable development, especially that of rational use of coastal zone resources. 相似文献

1 Introduction Northeast China consists of the three provinces of Heilongjiang, Jilin and Liaoning. Since the founding of the People's Republic of China in 1949, this region has supported the whole country with huge quantity of grain, raw materials, primary products, and heavy industrial products at the cost of environment and resources, and thereafter became an old industrial base as well as an important marketable grain base in the whole country (Zhang et al., 2004). However, since the 19… 相似文献
