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.   A preliminary investigation of CO2 and CH4 concentration variations with the land use in Northern China by GOSAT 会议论文  OAI收割 2010 30th IEEE International Geoscience and Remote Sensing Symposium, IGARSS 2010,, Honolulu, HI, United states, July 25, 2010 - July 30,2010 Lei, Liping ;  Liu, Qing;  Zhang, Li;  Liu, Liangyun;  Zhang, Bing  收藏  |  浏览/下载：16/0  |  提交时间：2014/12/07 Curing  Concentration (process)  Ecology  Geology  Global warming  Greenhouse gases  Mixing  Remote sensing   Remotely sensed study of air-sea CO2fluxes variability in the Northern South China sea 会议论文  OAI收割 2009 IEEE International Geoscience and Remote Sensing Symposium, IGARSS 2009,, Cape Town, South africa, July 12, 2009 - July 17,2009 Liu, Fenfen ;  Tang, Shilin;  Chen, Chuqun  收藏  |  浏览/下载：20/0  |  提交时间：2014/12/07 Atmospheric temperature  Atmospheric chemistry  Geology  Internet protocols  Ocean currents  Remote sensing  Salinity measurement  Seawater  Space optics  Surface properties   Changes in vegetation phenology in response to climate changes in Northern hemisphere between 1982 and 2006 会议论文  OAI收割 30th Asian Conference on Remote Sensing 2009, ACRS 2009,, Beijing, China, October 18, 2009 - October 23,2009 Liu, Ling-Ling; Liu, Liang-Yun 收藏  |  浏览/下载：9/0  |  提交时间：2014/12/07 Phenols  Biology  Ecology  Global warming  Remote sensing  Systems engineering  Vegetation   Researching on extracting irrigated land in northern China based on MODIS data 会议论文  OAI收割 2008 International Workshop on Earth Observation and Remote Sensing Applications, New York Dong, Tingting; Jiang, Miao; Qian, Fengkui; Zhang, Zengxiang 收藏  |  浏览/下载：9/0  |  提交时间：2014/12/07 Soil moisture retrieval from MODIS data in northern China plain using thermal inertia model (SoA-TI) 会议论文  OAI收割 IGARSS 2005: IEEE International Geoscience and Remote Sensing Symposium, Vols 1-8, Proceedings, New York Cai, GY; Wu, J; Xue, Y; Hu, YC; Guo, JP; Tang, JK 收藏  |  浏览/下载：11/0  |  提交时间：2014/12/07 thermal inertia  soil moisture  MODIS  SURFACE-TEMPERATURE  EARTH
