以石羊河流域中游为研究区,首先利用多时相、多源遥感图像提取土地利用/土地覆盖信息,根据转移矩阵,定量研究了景观类型的变化趋势、变化面积、变化率及具体的转换类型;提取能够反映景观格局特征的相关指数,分析景观生态格局及景观异质性;最后,对其景观格局变化的驱动因素进行分析.通过本次研究可以增强对石羊河流域中游生态环境的科学认识,对促进该流域的综合治理具有一定的科学和实际意义.

The middle Shiyang River valley with a sensitive ecological environment was chosen as the study area. First of all, land use/land cover information was extracted by using multi-temporal and multi-source remote sensing image. Then the landscape change tendency, change area, change rate and specific conversion type were studied quantitatively through the transfer matrix calculation. Through extracting characteristics of landscape pattern indexes, the regional pattern of landscape ecology and landscape heterogeneity were analyzed. Finally, the driving factors for landscape pattern change were investigated. This study is likely to deepen the scientific understanding of the ecological environment in the middle Shiyang River valley and can promote the comprehensive management of Shiyang River Basin, thus having both scientific significance and practical significance.
