Ecological Security Assessment of Lishui River Basin in Zhangjiajie City
摘要
Abstract
Taking Lishui River basin in Zhangjiajie city as the research object,through fieldwork,collec-ting historical data and on-site monitoring,combining with the domestic and foreign ecological security assessment theory,using the"pressure-state-function-risk-response"(PSFRR)model,the ecological se-curity assessment index system of Zhangjiajie Lishui River basin was constructed(5 factor layers,20 scheme layers and 43 index layers)to evaluate the ecological security index of the river basin.The results showed that the ecological security index of Zhangjiajie Lishui River basin was at a good level,and the ec-ological damage was controllable.Affected by human activities and agricultural development along the river,the habitat of the river basin was damaged,the integrity index of aquatic organisms was low,the water conservation capacity was insufficient,and the stability of the river basin ecosystem was threat-ened.In view of the problems mentioned and the requirements of river basin ecological protection,the corresponding measures and countermeasures were put forward from the aspects of river basin water eco-logical environment governance,ecosystem protection and restoration,ecological security management and the construction of river basin ecological environment protection system.关键词
