利用遥感、地理信息系统、地质统计学和景观格局分析软件等技术和工具，对塔里木河中游1986、1999和2005年的遥感影像进行了处理，分析了塔里木河中游地区景观格局变化特征和生态水文过程。在生态系统耦合关系的理论和方法指导下，分析了景观格局与生态水文过程的相互影响。结果表明，景观格局与径流变化存在相关性，景观多样性指数与径流相关性最大，景观优势度指数与径流变化的相关性最大，景观格局与径流变化的相关性最大。景观破碎化与径流也有相关性，景观形状指数与径流没有相关性，生态水文过程对景观格局也有一定的影响。
Based on the techniques and tools of RS,GIS,geo-statistics and landscape pattern analysis software,the remote sensing images of the middle reaches of Tarim River in 1986,1999 and 2005 were processed,and characteristics of landscape pattern changes and eco-hydrology process were analyzed.Then under the instruction of theory and method of ecosystem coupling relation,the mutual influence between landscape pattern and eco-hydrology process were analyzed.The results showed that there is relativity between landscape pattern and runoff change.Landscape diversity index has the biggest relativity with the runoff.The landscape dominance index,landscape fragmentation also has correlation with runoff.There is no correlation between the landscape shape index and the runoff.The eco-hydrology process also influence landscape pattern.
