Problems solved by technology

[0006] In order to solve the problems existing in the prior art, the present invention provides a protection vacancy analysis method and system for natural reserves. The method provided by the present invention combines regional-scale macro analysis with fine-scale micro-analysis of natural reserves, and solves the problem of natural reserves. Cross-overlap and integration optimization issues, scientifically and rationally realize the vacancy analysis of nature reserves, provide technical support for identifying current protection vacancy areas, and realistically carry out nature reserve planning

Embodiment 1

[0061] Example 1 Analysis of protection gaps in the surrounding areas of nature reserves

[0062] When analyzing the surrounding areas of nature reserves, remote sensing images with a resolution higher than 1 meter are used, such as the Gaofen-2 product. Through the buffer analysis, the boundary of the protected area is expanded by 5 kilometers, and the physical environment evaluation, biological environment evaluation and interference factor evaluation are carried out in sub-blocks within the 5 km range. Iterate successively until the surrounding area of ​​the protected area does not meet the requirements of being included in the protected area, as follows:

[0063] 1. Physical environment assessment

[0064] The present invention evaluates the physical environment of the surrounding area of ​​the nature reserve based on the spatial connection, for example, the spatial correlation between the nature reserve and its surrounding similar ecosystems.

[0065] The present invent...

Embodiment 2

[0078] Embodiment 2 Analysis of protection vacancies in the target area

[0079] 1. Regional scale macro analysis

[0080] Use remote sensing images with a resolution of 30 meters, such as Landsat8 products. Carry out ecosystem and natural resource assessment, biodiversity assessment and ecosystem service value assessment for the target area.

[0081] 1.1 Ecosystem and natural resource assessment

[0082] Consider the typicality, pristineness and fragility of ecosystems and natural resources. Joint evaluation using reference layer and calculation layer.

[0083] The reference layers are mainly geological and geomorphic maps, climate maps, soil maps, vegetation maps, etc. in the region, which are generated into raster layers with the same resolution as remote sensing images;

[0084] The calculation layers are mainly survey data such as geological relics, paleontological relics, fossils, typical climate (climate landscape), vegetation, and regional distribution maps of wate...

Abstract

The invention provides a natural reserve protection vacancy analysis method and system, and relates to the field of ecological protection, and the method comprises the steps: carrying out the unit-area incremental evaluation of a physical environment, a biological environment and an interference factor of a target region according to a natural reserve vector diagram in the target region under a large resolution, obtaining an analysis result of whether a protection vacancy area exists in the target area; before or during the process, acquiring spatial geographical environment data of a target area to construct a basic database; collecting data representing ecological system and natural resource distribution characteristics, data representing biological distribution characteristics and datarepresenting ecological system service characteristics, and constructing an index database; and processing the basic database and the index database to enable the basic database and the index databaseto perform calculation under high resolution so as to obtain a macroscopic evaluation result of the target area. The method can realize identification of the protected vacant area of the natural reserve, is beneficial to guidance of ecological restoration and is beneficial to ecological environment protection.

Description

technical field [0001] The invention relates to the field of ecological protection, in particular to an evaluation method and system for ecological protection of nature reserves. Background technique [0002] In 1956, my country established the first nature reserve - Guangdong Dinghushan Nature Reserve. Since then, China's natural ecosystem protection has developed rapidly. According to incomplete statistics, there are currently more than 12,000 nature reserves in mainland China, basically covering most of China's important natural ecosystems and natural heritage resources. In 2020, the "Letter of the National Forestry and Grassland Administration of the Ministry of Natural Resources on Doing a Good Job in the Preliminary Work of the Optimization and Adjustment of the Scope and Functional Zoning of Nature Reserves" (Natural Zihan [2020] No. According to the "Guiding Opinions on Establishing a System of Nature Reserves with National Parks as the Main Body" and "Guiding Opini...
