Water environment bearing capacity assessment early warning regulation and control method

Abstract

The invention discloses a water environment bearing capacity assessment early warning regulation and control method. The method comprises the following steps: setting three assessment indexes of a water environment, water ecology and water resources; carrying out environment bearing state and corresponding early warning grade division on the water environment; establishing a water environment bearing capacity evaluation pre-model; evaluating evaluation index data in a future preset time period and a corresponding early warning level; and regulating and controlling the evaluation indexes with high early warning levels in the future preset time period. According to the method, the coordination degree of water environment pollutant holding and purifying capacity, water resource endowment and utilization conditions, water ecological organism and physical habitat health and the like with social and economic development is comprehensively considered; a water environment bearing capacity assessment early warning index system is built according to the structures of the target layer, the criterion layer and the index layer; the water environment bearing overload condition is regulated and controlled, so that the water environment bearing capacity and indexes are developed towards higher quality; problems existing in current water environment management and social and economic development can be analyzed in a targeted mode, a reasonable regulation and control scheme is formulated, and watershed water environment pollution prevention and control are achieved.

Description

technical field [0001] The invention relates to the technical field of water resource control, in particular to a method for early warning and control of water environment carrying capacity assessment. Background technique [0002] Scholars at home and abroad have done a lot of research on the carrying capacity of resources and environment. From the initial single-factor resource and environment analysis to the later comprehensive factor analysis of resource environment and social economy, vector modeling methods, system dynamic models, scenario analysis methods, and state space analysis methods have emerged. Method, ecological footprint method, emergy analysis method, K-means clustering method, mutation progression method and other research methods. Emergy analysis is an ecological-economic system theory and method founded by Odum H T. The basic idea is to convert various forms of energy in the ecosystem into energy based on the most common solar energy through different em...

AI Technical Summary

Problems solved by technology

At present, the status and results of regulation and control programs are mainly demonstrated from the aspects of social economy and resources, and there is a lack of description of the carrying capacity and index status of control programs.
