摘要
分析景观格局在时空上的演变过程与河流径流量的相关关系,是认识干旱区生态环境变化的途径之一。采用监督分类的方法对叶尔羌河流域1990、2000、2005、2010年4期TM影像进行解译,获得土地利用/覆被数据,并进行景观类型综合处理,从时间和空间变化两个方面,在斑块水平、类型水平和景观水平方面分别探讨了新疆维吾尔自治区叶尔羌河流域近20年来景观格局的动态变化与水资源之间的关系,并分析了景观格局变化对河流径流量的综合作用。
Analyzing the correlation between landscape pattern evolution in time and space and river runoff is one way to recognize ecological environment change in arid area. Based on the land use / cover map of Yarkant River Basin in 1990,2000, 2005, 2010, the land use / cover data was obtained for integrated processing of landscape type. The relationships between changes of landscape pattern in recent twenty years and water resources was explored from both temporal and spatial aspects, which reflects the combined effects of landscape pattern change on river runoff.
