Abstract

The invention provides a method for four-stage zoning of a drainage basin with the combination of land area factors and water body factors. The method comprises the following steps: performing three-stage zoning on the basis of regional differentiation of land area factors which can affect and adjust the water amount and the water quality of a water ecosystem of a drainage basin, and with the combination of two-stage zoning layers, so as to generate three-stage zoning layers; according to regional differentiation of water body factors which can affect the aquatic organism environment of the drainage basin, performing main type zoning on a river reach of the drainage basin, and generating a main type set of the river reach; according to the three-stage zoning layers and the main type set of the river reach, generating an ecological function zoning diagram of the drainage basin. By adopting the method, the problem of spatial matching of land characteristics and water ecosystem characteristics of a water gathering area in the prior can be solved, therefore, the beneficial effect that the water ecosystem is protected by managing land spatial structures is achieved.

Description

technical field [0001] The invention relates to the field of computer graphics and image processing, in particular to a processing method for water ecological function-related data of a watershed, and in particular to a method for four-level division of a watershed by combining land area factors and water body factors. Background technique [0002] The characteristics of the basin water ecosystem are formed by the joint action of natural factors and human factors, among which the influence of human activities is far-reaching and strong. The analysis of the natural and human basic conditions for the formation of the basin water ecosystem is the basis for carrying out the division of the water ecological function of the basin and the comprehensive management of the water ecological environment of the basin. The development of social economy and the rapid increase of population have caused enormous pressure on regional water resources, the contradiction between supply and deman...
