An Analysis of the Landscape Ecological Health Evolution and Its Driving Factors of Luanhe River Basin
Based on the landscape ecology ,this study made the health assessment of landscape ecological conditions of Luanhe River Basin in three periods (1980s ,1990s ,2000s) with sub-basin as the unit .This study identifies its driving factors by analyzing the e‐volution trends of its ecological health and analyzes the correlation between those driving factors and landscape indexes .The results show that ,since the 1980s ,the landscape ecological health of the Luanhe River Basin presents a trend of worse and turns good .The landscape state of mountains is worse than that of the plains and the landscape ecology of plateaux is particularly unhealthy .The fac‐tors of human activity that affect its ecosystem health most are urbanization and soil and water conservation .As natural factors tem‐perature and precipitation ,also have an impact on the landscape ecological health .
