Embodiment

[0023] The present invention will be further described below with the endangered wild animals in a certain nature reserve as an example.

[0024] 1. Endangered wild animal screening and data collection

[0025] Select endangered wild animals in a nature reserve for analysis. Investigate the living habits of endangered wild animals in the field, collect natural factors and human factors that have a strong impact on the choice of habitat for this endangered wild animal, and then assign a value to each factor. The value range of the assignment is 0-100, 0 means no Suitable as a habitat for endangered wild animals, 100 means it can be used as a high suitability habitat for endangered wild animals, use the GIS software ArcGIS9.3, use the assigned field as the Value value, and convert each factor into a 30m×30m raster data . Then, the weight value between each factor is determined by expert scoring method and questionnaire method.

[0026] 2. Construct a GIS-based ecological nich...

Abstract

The invention discloses an endangered wildlife habitat suitability distinguishing method based on a GIS. The endangered wildlife habitat suitability distinguishing method includes the steps of firstly, determining the endangered wildlife required to be studied in a nature protection area, researching the nature and humanity conditions of the nature protection area and the life habits of the endangered wildlife, then carrying out outdoor data collection and space data compilation, selecting the nature factors and the human factors having great influences on the endangered wildlife, being free of the need to obtain the area where the endangered wildlife moves and appears in advance, building an ecological niche model based on the GIS, quantizing the habitat suitability, and dividing the habitat into the high-suitability habitat, the middle-suitability habitat, the low-suitability habitat and a non-suitability area. According to the endangered wildlife habitat suitability distinguishing method based on the GIS, wide-range suitable endangered wildlife habitat distinguishing can be achieved, limited manpower and material resources can be developed to the greatest degree, and therefore the wildlife habitat protection efficiency and the wildlife habitat protection benefits are improved. The method for calculating the wildlife habitat suitability is disclosed, the area which is required to be preferentially protected in the nature protection area can be visually reflected, and building, construction and management on the nature protection area are guided.

Description

technical field [0001] The invention discloses a GIS-based method for judging the suitability of endangered wild animal habitats, which is a new quantitative method for judging the suitability of wild animal habitats. The invention belongs to the technical field of wild animal protection and habitat division, and is an important basic work in the protection of endangered wild animals. Background technique [0002] The establishment of nature reserves and the protection of wild animal habitats are the main means of maintaining the survival and development of wild animals. The boundaries of nature reserves are delineated and the management agencies of nature reserves are established to reduce the consumption of wild animal resources caused by unnatural factors. Habitat is the most basic living space for wild animals. Wild animals will choose the area with the least restrictions on their own survival to maximize the suitability of their living conditions. Therefore, clarifying...
