特大干旱情景下供水侧极限调控与生态经济效应的响应关系研究
Study on the response relationship between water supply ultimate regulation and ecological economic effects under severe drought scenarios
摘要
Abstract
To mitigate severe drought disaster losses and ensure socio-economic growth,it's crucial to overcome con-ventional regulatory boundaries and augment potential supply,such as utilizing reservoir dead storage capacity and groundwater overexploitation,which may increase water supply and mitigate drought loss,delivering a positive impact,but could also inflict functional damage and destruction on the water supply system,leading to adverse effects.In this paper,under the comprehensive consideration of the social,economic and ecological environment impact brought by the extreme regulation measures on the water supply side,the ecological and economic effect com-position system is constructed.Based on the emergy theory and analysis method of ecological economics,the effect quantification system is proposed.Taking Chuxiong Prefecture of Yunnan Province as an example,the response rela-tionship between the increase of water supply,regulation cost and ecological and economic effects of the extreme regulation measures is analyzed.The results show that the two control measures of emergency backup water source and temporary emergency water supply have the largest net benefit of unilateral water,but the increase of water supply is limited,while the total increase of water supply and the total benefit of regulation and control are the largest when the dead storage capacity of the reservoir is used.Comprehensive discussion,the use of emergency standby water sources,the use of reservoir dead storage capacity and temporary emergency water supply are the priority con-trol measures under the severe drought situation in Chuxiong Prefecture.关键词
