【摘要】：利用Iandsat遥感影像数据(TM、ETM+),结合气象数据,通过土地利用类型转移矩阵,对和田地区该区域绿洲植被覆盖面积和时空格局变化进行分析,并结合和田地区政策、人口等因素对其驱动因子进行研究。结果表明:和田地区绿洲内的林地、耕地和水域面积呈现先减少,后缓慢增加的趋势,受雪山融水供给的影响,该地区水域变迁幅度较剧烈;受全球大气候与昆仑山南麓局地小气候的影响,该地区气温呈现稳定增加的趋势,而降水呈现先增加,后减少的趋势。
[Abstract]:Based on Iandsat remote sensing image data (TM,ETM) and meteorological data, the changes of vegetation cover area and spatial and temporal pattern of oasis in Hotan area were analyzed by using land use type transfer matrix, and the policy of Hotan area was combined. Population and other factors to study its driving factors. The results showed that the area of forest land and water area in Hotan Oasis decreased first and then increased slowly. Under the influence of the global climate and the local microclimate in the southern foot of Kunlun Mountains, the temperature in this area is increasing steadily, while the precipitation is increasing first, then decreasing.
