3S技术在草原资源与生态状况研究中的应用——以内蒙古自治区镶黄旗为例

Application of 3S Technologies(Remote Sensing,Geographical Information System, and Global Positioning System)to Assess the Resources and Ecology of the Grassland of Xianghuang Banner, Inner Mongolia

利用多期次的 TM遥感影像 ,结合全球定位系统支持下的地面精确定位调查 ,在地理信息系统平台上对镶黄旗草原资源与生态现状及历史动态进行了研究 ,完成了草原类型、面积、生产力、退化、沙化、盐渍化、草原生态保护建设工程的定性和定量分析 ,并研究 3S技术应用于草原资源与生态状况变化方面的方法体系。

Using multi-timed TM images, global positioning system, and geographical information system to study the grassland resources and the current ecological situation of Xianghuang Banner of Inner Mongolia, we have assessed and quantitatively analysed the grassland type, area, and productivity, the situation of degeneration, desertification and salinity of the grassland, as well as the effect of our ecological restoration projects in the region. We have also studied the methodology and data collection process of the 3S technologies.
