The analysis of Land-use change trends and its driving forces is one of the hot issues of global change research, the core of research is how to forecast the tendency of land-use change reasonably and accurately. The dynamic land-use change is very complicated, the traditional GIS method can solve part of the spatial correlation problem well, but it is hard to simulate complex dynamics in spatial...
Based on the data of multi-temporal point TM images, by applying the theory of Ecosystem Service Value, the Gravity Center Model, ESDA method and so on, the paper calculates the ecosystem service value in Circum-Taihu Lake region in 1985, 1995, 2000, 2005 and analyzes the characteristics of the gain and loss of the ecosystem service value, their spatial difference changes, the spatial pattern evolution...
This paper takes Fengxian in Jiangsu Province as an example, on the basis of Landsat TM/ETM+ images of four different time (1988, 1995, 2001, 2006) and aerial photographs of 2005, meanwhile, auxiliary data such as administrative vector map of Fengxian, land use map and socio-economic statistical data of 1995,2006. supported by RS and GIS technology, land use spatial database and attribute database...
With the development of economy, the social economy condition of Wuhan city has changed a lot. Land use change is the most remarkable among the changes which has deep influence on economy development, ecology change, and land sustainable development, et al, especially on the urbanization, more direct and remarkable. This article mainly analyzes Wuhan's land use change condition in the progress of...
There is vast territory in Sichuan province, but its per capita land area is lower than the average level of whole nation, and the serious contradiction between man and land always exists. So the study on the land use/cover condition and its dynamic change in Sichuan province is very important, which is also the significance of the paper. By advanced RS and GIS technology, the study centers around...
A case study on the impact of land use/cover change on shallow groundwater quality in the oasis over the Sangong River Basin, Xinjiang, China, is carried out by applying RS, GIS and geostatistical analysis. The data used in this study include the TM images in 1987, ETM images in 2004 and test data of groundwater quality sampled from 77 wells in 2004. Results indicate that the hydrochemical characteristics...
With the construction of the Three Gorges Project, the type of land use/land cover in Three Gorges Reservoir Region changed much, at the same time, the environment of the same region changed greatly, too. There is some relationship between the land use/land cover changes and environment changes, which is the reason of the paper. Firstly, the analysis of the TM remote sensing images in 1995 and 2008...
This paper analyzed the characteristics and major human driving forces of cultivated land change in Fuzhou, China, using remote sensing (RS) images, geographic information system (GIS) spatial analysis, and socio-economic data. Based on the RS images and GIS spatial analysis, a change matrix was constructed to detect land-use change from 1989 to 2005. The result indicated that paddy fields and dry...
Land use change is the most significant aspect in the research field of globe changing. Affected by both of natural and artificial factors, the land use and land resources quality varied continually. Dongguan City where the zone has a typical feature of land use change and significant ecological effects is selected as a case. This paper analyzed the spatial conversion of arable land in Dongguan city...
Urban expansion and land use change was studied in Jiangsu Province with RS and GIS technique, and driving forces was analyzed. Cities studied in this paper include 13 prefecture cities and 51 county cities. Remote sensing images include Landsat MSS, TM and ETM with time series from 1979 to 2000. Jiangsu Province lies in the southeast of China, which is one of the rapidest growing provinces along...
We analyzed land use changes and the characteristics of spatial structure in the progress of urbanization from 1991 to 2006, specifically, Huidong County of Guangdong Province. Based on the three temporal Landsat TM images during the study period, land use data of the area were obtained using the maximum likelihood classification method; and the structure of urban spatial development, central, transitional...
Eastern coastal area along Guangdong province is one of the economically developed regions in China which has experienced a lot of changes in its land-use patterns. It has become necessary to detect the changes happened in this region as this may help determining the level of stress that the coastal zone is facing and improving the management of the coastal resource. Based on the land use data acquired...
Sustainable hydropower, cascade development and construction not only bring regional land-cover changes, but also cause the change of ecological environment. So it is very important to assess the environmental impacts of hydropower development by analyzing the effects of the cascade hydropower development on the land-use changes. In this paper, CLUE-S model is applied to the cascade hydropower station...
