| 摘 要： | 利用1978年MSS及1987,1996和2007年Landsat TM/ETM遥感影像,借助GIS技术,对腾格里沙漠与毛乌素沙地南缘地带土地利用与气候变化的响应关系进行了研究.结果表明,研究区年均温升高,降水量减少,气候趋于暖干化,土地利用开发程度差异显著,表现出30 a来,毛乌素沙地南缘土地利用开发强度整体较大,高于腾格里沙漠南缘地带,在变化速度上,毛乌素沙地高于腾格里沙漠南缘地区.

| Abstract: | By using the MSS image in 1978 and Landsat TM/ETM images in 1987,1996,2007 with the help of GIS,the relationship between land use and the climate change in the southern marginal zones of Tengger desert and Mu Us desert in central of Ningxia from 1978 to 2007 were analyzed.The results showed that under the conditions that the climate in north China trends to warming and drying,especially,under the control of the water and heat conditions,the degree of land use difference was significant in the southern margi... |
