Analysis on evolution trend of ecological health in Luanhe River Basin
摘要
Abstract
In order to conduct an overall assessment for the development tendency of health ecosystem of Luanhe River Basin, the PSR model is established and the health conditions of ecosystem of the basin in three eras from 1980s to 2000s (the represent-ative years of 1985, 1995 and 2005) are assessed. On the basis of prediction on land utilization and various assessment indexes in 2015 and 2025, the pre-alarm analysis on ecological health of the basin in 2015 and 2025 is conducted. The results show that, from 1980s to 2000s, the ecological health of Luanhe River Basin presents a worsening trend from health to sub-health, but after 2010s, it has gradually restored to health.关键词
