Abstract

A lake basin hydro-ecological function three-level zoning method comprises: selecting a set of lake basin hydro-ecological function three-level zoning indexes, dividing a target basin DEM as a base map into zoning function units through hydrological analysis, spatially discretizing the zoning indexes on the zoning function units, and combining the similar hydro-ecological zoning function units with a second-order spatial clustering analysis method in combination with a lake basin hydro-ecological function two-level zoning boundary to preliminarily form a hydro-ecological function zoning draft; performing zoning check by utilizing hydro-ecological survey data, and adjusting the zoning indexes according to a zoning check result to correct the zoning draft; and finally determining a hydro-ecological function zoning boundary and making a lake basin hydro-ecological function three-level zoning map.

Description

technical field

[0001] The invention belongs to the technical field of environmental protection and comprehensive utilization of resources, relates to a water ecological function zoning technology of a river basin, and in particular relates to a three-level zoning method for the water ecological function of a lake-type watershed. Background technique

[0002] The water ecological function area refers to the water body with relatively consistent (potential) water ecosystem composition, structure, pattern, process and function and the land water aggregate with "water and land consistency". Repair provides the basis. The water ecological function area is proposed to meet the needs of the management of the water ecosystem of the river basin, with the goal of restoring the continuity and integrity of the watershed ecosystem, and taking the water ecosystems at different scales and their influencing factors as the research objects. The principle and method of the pattern and scale...
