Embodiment Construction

[0032] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principle of the present invention.

[0033] In the embodiment of the present invention, taking Balin Right Banner of Inner Mongolia as an example of the ecological restoration zoning, the ecological restoration zoning is demarcated hierarchically, and the specific steps are as follows. The data processing in the ecological restoration subregions is all performed by geographic information system software, and this embodiment specifically uses, but is not limited to, ArcGIS software.

[0034] 1. Obtain raw data such as administrative division data, elevation data, meteorological element data, land cover type data, and remote sensing images of the Bahrain Right Banner research area, perform pr...

Abstract

The invention relates to an ecological restoration partition method through combination of dominant ecological functions and ecological degradation degree. Original data of an area under research are acquired, preprocessing and information extraction are performed on the original data and an underlying data graph is drawn; four ecological function elements of water conservation, wind prevention and sand fixation, soil conservation and biodiversity maintenance are calculated; the ecological degradation degree is calculated and an ecological degradation degree graph is generated; an ecological restoration partition is divided into three levels and a partition graph of each level is generated; and the partition graphs of all levels are superposed so that a final ecological restoration partition graph is generated. According to the method, the limitation that the conventional ecological function partitioning only focuses on the main service function spatial layout of an ecological system can be overcome so that quantitative division of the ecological restoration partition can be realized, the targeted performance and the accuracy of the ecological restoration engineering can be enhanced and manpower and material resources can be saved.

Description

technical field [0001] The invention relates to the field of ecological restoration, in particular to an ecological restoration zoning method combining dominant ecological functions and ecological degradation degrees. Background technique [0002] With the development of economy and society, the contradiction between resource development and utilization and ecological environment protection is prominent, which is manifested by the increasing sensitivity of the ecological environment, and the human demand for ecosystem service functions is increasing. Therefore, reasonable arrangements for ecological restoration and economic development layout , carrying out ecological restoration scientifically and efficiently has become the focus of attention. The theory of ecological restoration zoning is based on ecological zoning, and the concept of ecological zoning was first proposed by Russian geographer Dokuchayev in 1899. In 1905, British ecologist Herbertson aimed at natural region...
