Abstract
[Objective] Using the environmental system analysis and evaluation technology,the security evaluation index system based on the reservoir-type water sources was explored and studied,so as to improve this kind of index system. [Method] Referring to the existing researches and taking water blooms as unsteady indicator, the safety evaluation index system of water environment based on five layers (driving forces, pressure, state, impact, risk) and eleven indicators was built. [Result] According to integrated evaluation of weighted sum,the security levels of the water source are divided into high warning state, middle warning state, prewarning state, relative security state and security state. [ Conclusion ] The index system evaluation method is simple,which reveals the main risk of the water source and the main problems,and provides theoretical basis and scientific reference for government departments at all levels to balance daily life,production and ecological water use,and safeguard people's life and health.关键词
