中文摘要	土地利用及景观变化是全球变化研究的核心议题。玛纳斯河流域是干旱区典型的山地-绿洲-荒漠生态系统,在3S技术下,采用定量分析方法,研究玛纳斯河流域的景观分异特征,并进一步分析所带来的水文生态效应,结果表明:(1)玛纳斯河流域土地利用的人工化和集约化趋势明显,生态景观持续弱化;(2)特殊的山地-绿洲一荒漠生态系统使得土地利用变化存在着区域差异,表现在绿洲区土地利用趋向高度人工化和结构稳定性,绿洲区外围则趋向高度敏感化与生态脆弱性;(3)山地区、绿洲区和荒漠区呈现出不同的景观分异特征。在山地区,洪积扇上部的开发导致了景观多样性的增加。在绿洲区,斑块的分布更加邻近且趋向简单化和归一化。荒漠区的景观变化较为复杂,以水域的连通性和优势度降低,未利用地的破碎化加大为主;(4)玛纳斯河流域的景观变化扰乱了上游水文循环、弱化了下游水资源分配。
英文摘要	Land use and landscape change are the core issues of global change research. Manas River Basin is a typical mountain-oasis-desert ecosystem in the arid areas. Based on the 3S technology and using the method of quantitative analysis the characteristics of landscape differentiation and its hydro-ecological effect in Manas River Basin were examined. The results showed that: (1) the artificialization and intensive trend of land use were obvious, ecological landscape continued to weaken; (2) land use changes presented the regional differences due to the special mountain-oasis-desert ecosystem, land use tended to highly altitude artificialization and structure stability in oasis area, then tended to highly sensitive and fragile ecology in periphery of oasis; (3) in mountain areas,oasis areas and desert areas, the characteristics of landscape differentiation was different ,the development of foreland pluvial fan led to the increase of landscape diversity in mountain areas; the distribution of patch became more nearby and tended to simplification and normalized in oasis areas; landscape pattern change was more complicated in desert areas, giving that the priority of the dominance and dominance index of water area decreased,the fragmentation of unused land increased; (4) the landscape change disrupted the hydrologic cycle in the upper reaches of Manas River, weakened the water resources allocation in the lower reaches of Manas River.
