Embodiment 1

[0078] Embodiment 1 of the present invention takes the landscape ecological restoration of a small-scale industrial and mining abandoned site in a village in northern my country as an example, and provides an ecological security assessment and optimization method for land-based abandoned sites. The small industrial and mining abandoned site was originally the production site of a metal production company in a village and town. After the company stopped production, the site was abandoned.

[0079] Step 201: Carry out a site survey for the abandoned small-scale industrial and mining sites.

[0080] In this step, the site survey may include pollution source survey, regional scope survey and ecosystem survey, etc.

[0081] 1) Pollution source investigation: Carry out pollution source investigation on this small industrial and mining waste site. The scale of the site is about 35m long from east to west, 30m wide from north to south, and covers an area of ​​about 1000m 2 , the main...

Embodiment 3

[0126] Embodiments of the present invention also provide an ecological security assessment and optimization system for abandoned land sites, see image 3 ,include:

[0127] A site survey unit 301, configured to conduct site surveys on selected abandoned land sites;

[0128] A pollution level determination unit 302, configured to determine the pollution level of the abandoned land site according to the site survey results;

[0129] The minimum cumulative resistance calculation unit 303 is configured to analyze the resistance factor model of the abandoned land site according to the site survey results, and calculate the minimum cumulative resistance of the abandoned land site and its corresponding migration route;

[0130] The indicator acquiring unit 304 is configured to acquire an ecological security assessment indicator of the abandoned land site according to the pollution level of the abandoned land site and its minimum cumulative resistance.

[0131] The comparison and op...

Abstract

The invention provides an ecological security evaluation and optimization method and system for an abandoned land site. The method includes the steps that site investigation is conducted on a selected abandoned land site; the pollution level of the abandoned land site is determined according to the site investigation result; a resistance factor model analysis is conducted on the abandoned land site according to the site investigation result; the minimum cumulative resistance and the corresponding migration path of the abandoned land site are calculated; the ecological security evaluation index of the abandoned land site is obtained according to the pollution level of the abandoned land site and the minimum cumulative resistance of the abandoned land site; ecological restoration technical scheme comparison and optimization are conducted on the abandoned land site according to the ecological security evaluation index result. According to the ecological security evaluation and optimization method and system, the ecological security evaluation and optimization method and system which are high in operability are provided from the viewpoint of ecological safety according to the landscape ecological restoration technical requirements of the abandoned land site.

Description

technical field [0001] The invention relates to the technical field of land ecological restoration, in particular to a method and system for evaluating and optimizing ecological security of abandoned land areas. Background technique [0002] Abandoned land area mainly refers to the plots where the land loses its original function due to the accumulation or burial of a large amount of industrial waste or domestic waste. Due to the pollution of industrial waste residue or domestic waste, land waste sites usually accumulate high concentrations of organic or inorganic pollutants, which destroy the vegetation, animals and microbial ecosystems on them. Its hazards mainly include: (1) The accumulation of industrial waste or domestic waste not only occupies a large amount of land resources, but also causes damage to natural or cultural landscapes; (2) The accumulation or buried industrial waste and domestic waste contains heavy metals and organic Pollutants are extremely easy to in...
