中文摘要	如何量化人为活动对土地利用格局变化的影响是国内外学者所关注的热点问题,目前涉及人为影响空间分布特征的研究尚不多见.塔里木河上游地区是典型的生态脆弱带和环境危机带,对以人类活动为主导的区域水土资源的开发反响强烈,主要表现在其土地利用的空间格局随水土资源开发程度而发生的变化.本研究借助于3S技术和地统计学的空间分析方法,较系统分析了1990-2002年塔里木河上游地区阿克苏绿洲土地利用的时空变化特征,建立人为影响指数,定量揭示人为开发利用活动的空间变异、强度分布.研究表明,以阿克苏绿洲中心所在的人工绿洲系统为人为影响程度相对高的区域,广大的荒草地、沙地和部分水域为人为影响低的区域.2002年的人为影响特征与1990年相比,出现了较大变化,人为影响指数较高的区域面积在不断扩大,这与近年来当地人口数量上升导致的城乡建设用地面积增加和通过毁林、毁草来拓垦耕地有直接关系.
英文摘要	It is important to evaluate quantitatively human impacts on patterns of land use in the geography field. The upper reach of the Tarim River belongs to typical ecological fragile zone and environmental critical zone. Many intensive effects are caused by the utilization of land and water resources. Along with further development and utili-zation , great changes of land use pattern have been taken place. Studies on human impact on land use within the re-search area are important for the sustainable development and conservation of the entire basin. Based on the multi-temporal remote sensing data of TM, this paper attempts to reveal the spatio-temporal trends of land use in the Ake-su oasis from 1990 to 2002 with the technology of RS,GIS and GPS. The relations between land use change and hu-man impacts were analyzed. A spatial variance of human impact index was raised to express the spatial distribution of human exploiting and using strength by geostatistics tool. Using this index, the authors studied the spatial charac-teristics of human exploiting and using strength. The research shows that the changes of pattern are notable and hu-man impact is continuously enhanced. The land use types such as cropland, residential area, and saline land in-creased rapidly in contrast to reductions of grassland, forest, water area, and wetland. There are higher human im-pacts on the Akesu artificial oasis system while there are lower human impacts on surrounding grassland, sandy land and partial water body. There are great changes of spatial distribution of human impact indexes during the 12-year’ s study period. The scope of higher indexes’ area is increasing. The maximum of indexes increased from 0. 42 in 1990 to 0. 51 in 2000. The spatial characteristics of human exploiting and using had strong relations with the area of forest and grassland decreasing due to their conversion to cropland. With further analysis, more impersonal indexes could be presented to provide a better foundation for sustainable construction of oasis areas.
