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.   Study on Dynamical Visualization of Marine Current Data Field based on Base State with Amendments Spatio-temporal Model 会议论文  OAI收割 Proceedings of the 2009 2nd International Congress on Image and Signal Processing, Vols 1-9, New York Liu, Jian; Zhang, Xin; Li, Kai 收藏  |  浏览/下载：7/0  |  提交时间：2014/12/07 A spatial-temporal contextual classification approach based on Markov random fields using multi-temporal imagery 会议论文  OAI收割 MIPPR 2009 - Pattern Recognition and Computer Vision: 6th International Symposium on Multispectral Image Processing and Pattern Recognition, Yichang, China, October 30, 2009 - November 1,2009 Fu, Wei; Guo, Ziqi; Zhou, Qiang 收藏  |  浏览/下载：14/0  |  提交时间：2014/12/07 Hidden Markov models  Computer vision  Maximum likelihood estimation  Pixels  Structural frames   Analysis of land cover changes using multi-source and multi-temporal images in loess hilly and gully regions 会议论文  OAI收割 2nd International Conference on Earth Observation for Global Changes, Chengdu, China, May 25, 2009 - May 29,2009 Wang, Dongchuan; Gong, Jianhua; Zhang, Lihui; Lei, Qixiang; Cao, Quanyi 收藏  |  浏览/下载：14/0  |  提交时间：2014/12/07 Soil conservation  Ecology  Image processing  Land use  Landforms  Observatories  Soils  Support vector machines   Study on spatio-temporal change of cultivated land in Xinxiang City using remote sensing and GIS 会议论文  OAI收割 International Conference on Earth Observation Data Processing and Analysis, ICEODPA,, Wuhan, China, December 28, 2008 - December 30,2008 Qiao, Zhuping; Zhang, Zengxiang; Wen, Qingke; Wei, Xianhu 收藏  |  浏览/下载：10/0  |  提交时间：2014/12/07 Data processing  Geographic information systems  Observatories  Remote sensing  Time series  Transfer matrix method   Mining moving objects trajectories in Location-based services for spatio-temporal database update 会议论文  OAI收割 Geoinformatics 2008 and Joint Conference on GIS and Built Environment: Geo-Simulation and Virtual GIS Environments, Guangzhou, China, June 28, 2008 - June 29,2008 Guo, Danhuai; Cui, Weihong 收藏  |  浏览/下载：10/0  |  提交时间：2014/12/07 Mining  Data processing  Encoding (symbols)  Geographic information systems  Indexing (of information)  Knowledge management  Telecommunication equipment  Trajectories  Virtual reality
