| 摘 要： | 土地利用／土地覆被变化改变了地表生态系统组成结构，影响着生态系统功能，威胁着区域生态安全。本文以辽河流域的浑河-太子河流域为研究区，探讨了流域空间尺度上的LUCC特征及其所带来的生态效应。研究表明，不同的生态指标对LUCC的响应程度略有不同：（1）从景观生态格局角度看，反映生态系统斑块形状特征的景观指数对LUCC的响应...

| Abstract: | Land-use/land-cover change(LUCC) has effects on the composition of the surface structure of the ecosystem and ecosystem function,and threatens the regional ecological security. In this paper,the Hunhe-Taizi river watershed is taken as the study area,and land-use/land-cover data are extracted from satellite images acquired by Thematic Mapper(TM) sensor onboard Landsat-5 with object-oriented and interpretation methods in 1992 and 2007,then the ecological effect of LUCC in a basin scale. The results show that ... |
