| 摘 要： | 运用GIS和RS技术,以LandsatTM为数据源,监测我国草地资源的变化情况。研究表明,我国草地总面积增加,其中,高覆盖度与中覆盖度草地面积增多,但低覆盖度草地面积减少。而且南北方有差异,南方的草地面积变化较小,北方草地面积减少程度大,这对我国北方的生态环境将产生不利影响。

| Abstract: | The authors monitored dynamic changes of China's grassland by using TM datum based RS & GIS technology. The results show that the total grassland area in China was increasing from 1995 to 2000 with the increasing of high and middle cover grassland area, nevertheless, the area of low cover grassland was to some extent decreasing. Moreover, there is obvious difference in this aspect between north China and south China: the grassland area is decreasing remarkably in north China, which will exert harmful influence on the ecological environment of north China. |
