摘要
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, then the ecological effect of LUCC in a basin scale. The results show that different ecological indicators have different responses to LUCC: 1) from the perspective of the landscape ecological pattern, some indexes in response to LUCC is weak, which mainly reflects the shape of landscape patch; and 2) from the perspective of ecological functions, LUCC was better in some single factors of ecological function.
