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.   Distribution Characteristics of Organochlorine Pesticides in Western Songnen Plain, China 会议论文  OAI收割 International Symposium on Environmental Science and Technology, Shanghai, PEOPLES R CHINA, JUN 02-05, 2009 Yan Baixing; Cao Huicong; Luan Zhaoqing 收藏  |  浏览/下载：10/0  |  提交时间：2011/07/20 agricultural runoff  BHC  DDT  western Songnen Plain  mallard eggs
