摘要
通过对1961～2001年41年来阿克苏-阿瓦提荒漠绿洲的三个气象台站的气温、降水、沙尘天气、相对湿度资料的分析;同时选取1990年和2000年两景TM影像,采用遥感（RS）、地理信息系统（GIS）和全球定位系统（GPS）技术相结合的手段,利用景观生态学相关理论对生成的景观类型图进行分析和统计。结果表明：阿克苏-阿瓦提荒漠绿洲气候变化表现为气温升高、降水增多、沙尘天气减少、相对湿度增加的变化趋势;同时表明,干旱气候的变化是造成阿克苏-阿瓦提荒漠绿洲水资源、草场及林地、土地荒漠化及盐碱化、湿地资源变化的重要因素。
Analyze the data of air temperature, precipitation, dust weather and relative humidity at 3 meteorological stations in Akesu-Awati desert-oasis from 1961 to 2001; At the same time, choosing two scene TM images of 1990 and 2000, and adopting remote sensing （RS）, geographical information system （GIS） and global positioning system （GPS） technology, analyze and calculate the pictures of landscape type by the relevant theories of landscape ecology. The results show that air temperature appears to be increasing tendency, precipitation is increasing, dust weather is reducing and relative humidity is increasing in Akesu-Awati desert-oasis. At the same time, the change of arid climate is an importance factor to the changes of meadow and forest land, soil desertification and Stalinization, water resource and wetland resource in Akesu-Awati desertoasis.
