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...
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...
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...
