Embodiment

[0034] This embodiment provides a health assessment method for eutrophic lakes, such as figure 1 As shown, the method includes the following steps:

[0035] (1) Determine the evaluation index system

[0036] According to the needs of lake management, starting from the watershed as a whole, the natural attribute indicators that maintain the life and health of eutrophic lakes are analyzed, and at the same time, the social attribute indicators that lakes serve the sustainable development needs of human society are considered. Index screening follows the principles of systematicness, scientificity, representativeness, comparability, operability, practicality and easy access to data. Lake natural attribute indicators mainly involve the lake’s natural form, water quality and eutrophication, aquatic ecology and other indicators, reflecting changes in the lake’s natural form, water quality, ecosystem balance and other natural attributes; social attribute indicators mainly involve flood...

Abstract

The invention discloses a health evaluation method for eutrophic lakes, which comprises the following steps of: 1, according to the requirements of lake management, starting with an integral river basin, and determining a comprehensive evaluation index system containing the natural attribute for maintaining the life health of the eutrophic lakes and the social attribute of the lakes for satisfying sustainable development demands of human society; 2, establishing an evaluation model including a data entry and processing calculation module, a single factor evaluation calculation module and a comprehensive evaluation calculation module based on the multifactor comprehensive principle and the fuzzy relation synthesis principle according to the comprehensive evaluation index system established in the step 1; and 3, entering basic data to the evaluation model, and performing the health evaluation of the lakes by a calculation result outputted by the evaluation model. By the method, the health condition of the eutrophic lakes can be determined quickly, model software has the advantages of visual result expression, convenience for application and the like, and an effective technical management tool can be provided for the lake management.

Description

technical field [0001] The invention belongs to the field of water ecology, and relates to an ecological model construction, calculation method and software fitting, in particular to a health evaluation method of eutrophic lakes. Background technique [0002] Lakes provide abundant resources for human development and play an extremely important role in ensuring sustainable economic and social development. However, with the acceleration of industrialization and urbanization, the impact of human activities on lakes is increasing, pollution and eutrophication are serious, ecological functions are shrinking and degrading, and cyanobacteria blooms frequently occur, which directly affect human production and life. Eutrophication of lakes has become an important factor restricting economic and social development. In order to strengthen the health management of eutrophic lakes, keep abreast of the development trends of eutrophic lakes, maintain a healthy lake with self-adaptability...
