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...
Urban land-use patterns change has become one of hot topics on land use/ land cover change (LUCC) studies in the worldwide area. As urban land change is influenced by both topography and human behavior driving factors, it is a complex dynamic and spatio-temporal progress. To simulate and analyze urban land use patterns and its driving factors, the logistic regression model is implemented as the statistical...
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...
Regional land use change has been and will continue to be one of the hugest human impacts on the environment. Based on eight remotely sensed images of Guiyang city from 1973 to 2001, this paper studies the effect of urban sprawl on the land use and land cover of Guiyang in recent three decades. The process and characteristics of urban expansion and the surrounding land use change were analyzed. Besides,...
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...
