The decreases in farmland and the increases in grassland area mainly resulted from the policy of grain for green and converting slope farmland into pasture from China government. In spite of the efforts to conserve the fragile ecosystem  the land degradation  including soil salinization and grassland degradation  was spreading rapidly. The area of alkali-saline land increased by 22493 ha and about 50555 ha of dense grassland degraded into mid-density grassland. In terms of landscape fragmentation  both farmland and dense grassland showed the tendency of increased fragmentation. Both adverse natural conditions and human activities are responsible for the land degradation expansion in Hetao irrigation district  but the root causes are increasing population pressure and irrational human activities  such as flooding irrigation method and over-grazing. To prevent land degradation from spreading  population control and improvement of the management are prerequisite approaches. 2010 SPIE.   Effects of land use and land cover change on ecosystem service values in oasis region of northwest China 会议论文  OAI收割 Proceedings of SPIE - The International Society for Optical Engineering International Symposium on Photoelectronic Detection and Imaging 2009 - Advances in Imaging Detectors and Applications, Beijing, China, 2009 Huang; Qing1; 2; Li; Dan-Dan1; Zhang; Hong-Bin1 收藏  |  浏览/下载：15/0  |  提交时间：2011/08/23 Arid regions - Detectors - Economics - Farms - Forestry - Image reconstruction - Land use - Landforms - Remote sensing - Strategic planning - China - Driving forces - Dynamic changes - Economic development - Ecosystem functions - Ecosystem service values - Ecosystem services - Ecosystem services value - Ecosystem structure - Forest land - Gobi desert - Land use and land cover change - NorthWest China - Remote sensing images - Tarim River basin   GIS-based Assessment on Eco-Vulnerability of Jiangxi Province 会议论文  OAI收割 Fan Z.
