Small artificial lake reservoir ecology health assessment method

Abstract

The invention discloses a small artificial lake reservoir ecology health assessment method. The method comprises the steps of S1, performing analysis and confirmation on current situations of environments of regional lake reservoirs; S2, determining a structure of an assessment index system for characteristics of a target lake reservoir; S3, determining an assessment weight by adopting an analytichierarchy process, and performing parameter weight allocation according to an actual problem, thereby establishing an assessment standard system; S4, building a comprehensive assessment model, namely, an analytic hierarchy process-variable weight-fuzzy-grey correlation composite model; and S5, forming an ecology health assessment report, thereby finishing ecology system health assessment of a researched regional lake. The method has the beneficial effects that by comprehensively considering multiple influence factors, the ecology health of a small artificial lake reservoir is comprehensivelyanalyzed and assessed to obtain a more objective and accurate assessment result.

Description

technical field [0001] The invention relates to the technical field of ecological environment evaluation, in particular to a method for evaluating the ecological health of a small artificial lake. Background technique [0002] Ecosystem is the most basic unit to maintain human environment, and ecosystem has ecosystem service function and value function. A healthy ecosystem has the ability to maintain the integrity of its organizational structure and functional stability, self-regulation and recovery from stress, and can provide the necessary natural resources and living environment for human survival and development. As an important water ecosystem, the lake system not only has natural functions such as flood regulation and storage, water purification, ecological environment improvement, and providing an excellent habitat for aquatic organisms, but also has economic functions such as fish farming, urban water supply, and entertainment. Maintaining the health and stability o...

AI Technical Summary

Problems solved by technology

The main reason is that there is insufficient understanding of the function, structure, and health evolution of the lake ecosystem, and it is impossible to scientifically formulate the basis for lake environmental management and remediation measures.
