STUDY ON THE SPATIAL PATTERNS OF LAND-USE CHANGE AND ANALYSES OF DRIVING FORCES IN NORTHEASTERN CHINA DURING 1990-2000 总被引：4，自引：1，他引：3
Land-use change is an important aspect of global environment change. It is, in a sense, the direct result of human activities
influencing our physical environment. Supported by the dynamic serving system of national resources, including both the environment
database and GIS technology, this paper analyzed the land-use change in northeastern China in the past ten years (1990–2000).
It divides northeastern China into five land-use zones based on the dynamic degree (DD) of land-use: woodland/grassland —
arable land conversion zone, dry land — paddy field conversion zone, urban expansion zone, interlocked zone of farming and
pasturing, and reclamation and abandoned zone. In the past ten years, land-use change of northeastern China can be generalized
as follows: increase of cropland area was obvious, paddy field and dry land increased by 74.9 and 276.0 thousand ha respectively;
urban area expanded rapidly, area of town and rural residence increased by 76.8 thousand ha; area of forest and grassland
decreased sharply with the amount of 1399.0 and 1521.3 thousand ha respectively; area of water body and unused land increased
by 148.4 and 513.9 thousand ha respectively. Besides a comprehensive analysis of the spatial patterns of land use, this paper
also discusses the driving forces in each land-use dynamic zones. The study shows that some key biophysical factors affect
conspicuously the conversion of different land-use types. In this paper, the relationships between land-use conversion and
DEM, accumulated temperature (⩾10°C) and precipitation were analysed and represented. We conclude that the land-use changes
in northeast China resulted from the change of macro social and economic factors and local physical elements. Rapid population
growth and management changes, in some sense, can explain the shaping of woodland/grassland — cropland conversion zone. The
conversion from dry land to paddy field in the dry land — paddy field conversion zone, apart from the physical elements change
promoting the expansion of paddy field, results from two reasons: one is that the implementation of market-economy in China
has given farmers the right to decide what they plant and how they plant their crops, the other factor is originated partially
from the change of dietary habit with the social and economic development. The conversion from paddy field to dry land is
caused prmarily by the shortfall of irrigation water, which in turn is caused by poor water allocation management by local
governments. The shaping of the reclamation and abandoned zone is partially due to the lack of environment protection consciousness
among pioneer settlers. The reason for the conversion from grassland to cropland is the relatively higher profits of farming
than that of pasturing in the interlocked zone of farming and pasturing. In northeastern China, the rapid expansion of built-up
areas results from two factors: the first is its small number of towns; the second comes from the huge potential for expansion
of existing towns and cities. It is noticeable that urban expansion in the northeastern China is characterized by gentle topographic
relief and low population density. Physiognomy, transportation and economy exert great influences on the urban expansion.

A new technique designed to help quantify the degree of damage to the landscape from one area to another shows a close relationship
between population density and the degree of landscape damage. The technique establishes a scale of damage from 0 to 5 (zero=no
damage; 5=severe damage) using data from aerial photographs, land-use maps, and field data. The related formula allows one
to compare the relative degree of damage across regions using a combination of an absolute index, a theoretical index, a relative
index, and population density. Xing an County is used to demonstrate the technique. 相似文献

This paper describes a GIS-based spatial analysis method that combines qualitative analysis and quantita-tive analysis to characterize land-use patterns and predict the trend of future land-use changes in Halzhu District ofGuangzhou City, China. Spatial technique is introduced to manage land-use data and derive information of land-usechanges. Through the case study for the selected area, it is demonstrated that the method and technique introduced in thepaper can be effectively utilized for the analysis of urban land-use changes. Based upon this analysis, the paper also pro-vides discussions and recommendation on urban land-use planning, urban planning and land management. Both land-usemaps of Haizhu District of Guangzhou in 1995 and 1997 and the remote sensing images of 1999 are utilized in the cur-rent research. It is convenient to get various statistic data and to combine attribute data with spatial data so as to analyzeland-use changes in a geographic context, which is especially suitable for the need of urban construction department, ur-ban management department and urban planning department. 相似文献

Evaluation and analysis of provincial differences in resources and environment carrying capacity in China 总被引：2，自引：0，他引：2
Resources and environment carrying capacity is central to not only regional sustainable development but also major function-oriented zoning. This paper presents an evaluation index system for resources and environment carrying capacity based on four aspects of carrying capacity(i.e., water resources, land resources, the environment, and ecosystems) by using a square deviation decision-making method, and on the basis of above effort evaluates the resources and environment carrying capacity across 31 provincial regions in China(not including Hong Kong, Macau and Taiwan regions of China). In addition, this paper evaluates the current state of socio-economic development, and analyzes the spatial distribution of resources and environment pressure. The results showed that distinct spatial differences in resources and environment carrying capacity and pressure across provincial regions. Resources and environment pressure is affected by both comprehensive resources and environment carrying capacity and socio-economic development. Regions subjected to lower degrees of resources and environment pressure will be restricted by resources and environmental problems through future courses of development owing to excessively low carrying capacities. By contrast, regions with higher comprehensive resources and environment carrying capacity will be subjected to excessively high levels of resources and environment pressure because of rapid socio-economic development. Both of resources and environment carrying capacity and pressure must therefore be considered in the allocation of country-binding targets to provincial regions. 相似文献

To solve the problems caused by irrational land-use, studying the functions of land-use, its changing characteristics, and the relationship between each land-use function will be beneficial for achieving sustainable land development. In this research, we constructed an evaluation framework of multiple land-use functions(LUFs) based on sustainable land-use theory. Specifically,, we classified the multiple LUFs into three types: agricultural production function(APF), living function(LVF), and ecological service function(ESF).We then spatialized the economic and social data, and implemented the InVEST(Integrated Valuation of Ecosystem Services and Tradeoffs) model and RUSLE(Revised Universal Soil Loss Equation) model to evaluate each sub-LUF(crop production, aquatic production, woodlands production, livestock production, living space, life quality, water supply, soil conservation, climate regulation, biological conservation) in central China in 2000 and again in 2015. Moreover, by analyzing the changes to LUFs and the relationships between each LUF change, we were able to discern patterns of LUF change in central China. The results show that: 1) 42.12% of total territory in the study area increased their APF from 2000 to 2015, while 43.41% of the lands increased their ESF yet only 8.98% of the lands increased their LVF; 2) in Hubei and Hunan, there was more land with an increase of APF than in Anhui or Jiangxi. The APF in Jiangxi exhibited the greatest decline over time period, the LVF increased more in the provincial capital cities than in other regions, and the ESF expanded more in Jiangxi than in the other provinces; and 3) the changes in APF were significantly and positively correlated with changes in LVF. Additionally, changes in ESF were negatively but non-significantly correlated with changes in APF and LVF. 相似文献
