Urban inland river ecosystem health assessment method based on weights

Abstract

The invention discloses an urban inland river ecosystem health evaluation method based on weights, comprising the following steps: (1) distinguishing a reference point and a damaged point; (2) establishing a candidate microbial parameter index database; (3) screening core microbial parameters and parameter assignment; (4) calculating the microbial integrity index and dividing it into evaluation grades; (5) testing the reliability of microbial integrity index. The invention integrates the principal component weighting method, the entropy weight method and the biological integrity index method to evaluate the urban inland river with the microorganism as the research object, which has strong sensitivity and can reflect the health status of the urban inland river ecosystem quickly, sensitively, accurately and comprehensively and objectively.

Description

technical field [0001] The invention relates to the technical fields of environmental pollution monitoring and environmental protection, in particular to a method for evaluating the health of urban inland river ecosystems based on Ba-IBI. Background technique [0002] The construction and development of ecological cities are inseparable from water resources. Residents must have sufficient water security for their lives, and industrial production must have sufficient water resources. A beautiful urban environment is inseparable from a clean and good water ecosystem. Climate, dilution of sewage, drainage of stormwater, and landscaping play an important role. The urban inland river is the key link in the construction of an ecological city. However, with the development of the economy and the improvement of people's living standards, the water quality of urban inland rivers has deteriorated, the shape and structure have been destroyed, the hydrological conditions have changed, ...

In addition, compared with individual microorganisms, the above indicator organisms have a longer growth cycle and higher tolerance, and slight changes in the living environment have little effect on the population abundance of these indicator organisms, while microorganisms have a shorter survival time and faster growth rate, so they are different from Compared with fish, algae and macrobenthos, etc., they are more sensitive to changes in the living environment
