Problems solved by technology

Although my country has basically completed the national water environment function zoning work, from the perspective of ecological management, the water environment function zoning is not established based on the characteristics of regional water ecosystems, lacks consideration of regional water ecological functions, and cannot meet the needs of water ecology. Technical requirements for functional management of system protection

Embodiment Construction

[0041] The specific embodiments of the present invention will be described in detail below, but it should be pointed out that the protection scope of the present invention is not limited by these specific embodiments, but is determined by the claims.

[0042] Process flow of the present invention such as figure 1 shown. Taking the three-level zoning of the Taihu Lake Basin as an example, based on the results of the water ecological function zoning of key river basins in the country, especially the relevant achievements of the "Basin Water Environment Ecological Functional Division and Quality Objective Management Technology" project in the major science and technology project of water pollution control and treatment, the Taihu Lake Basin The third-level zoning uses water system category, water surface ratio, and river network node density as zoning indicators, and is divided into 13 zoning areas (see figure 2 ). The purpose of the third-level zoning is to reflect the impact...

Abstract

The invention discloses a subdivision method coupling watershed aquatic ecological function zoning with ecological management. Through aquatic ecological indexes and spatial element indexes, and on the basis of the three-level aquatic ecological function area, division of an aquatic ecological environment function management area is performed in combination with administrative division, development zone distribution, land use, important protected areas and distribution of important species, and the area division indexes are dispersed and clustered spatially on the basis of a division functional unit, and the coupling coordination degree of ecological management indexes and aquatic ecological indexes is tested to form a subdivision map of an aquatic ecological environment functional management area which is feasible for management.

Description

technical field [0001] The invention relates to a method for zoning water ecological functions, in particular to a subdivision method for coupling water ecological function zoning and function management in a watershed. Background technique [0002] Water environment problems in my country's river basins are prominent, and the water ecosystem has been destroyed. The survey shows that 57% of the rivers in our country are seriously polluted, which has led to a significant degradation of the water ecosystem functions in the country's river basins. Although my country has basically completed the national water environment function zoning work, from the perspective of ecological management, the water environment function zoning is not established based on the characteristics of regional water ecosystems, lacks consideration of regional water ecological functions, and cannot meet the needs of water ecology. Technical requirements for functional management of system protection. The...
