| 摘 要： | 在遥感、GIS及地统计学和景观格局分析软件的支持下,处理了塔里木河中游1986、1999及2005年的三期遥感影像,而后对中游景观格局动态变化及生态水文过程的基本特征进行了系统分析。在此基础上,在生态系统耦合关系理论与方法的指导下,重点对景观格局和生态水文过程的相互影响进行了探讨。分析表明,景观格局和径流的变化之间存在相关性。与径流相关性最大的是景观多样性指数,它们之间呈正相关关系。景观的优势度与径流量也呈正相关关系,而景观形状与流域径流之间不存在必然联系,景观破碎度与流域径流也有较大的相关性,但它们之间呈负相关关系。同时水文过程对宏观景观格局的变化起指导作用。

| Abstract: | 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. |
