Problems solved by technology

The rapid development and construction activities have caused the continuous encroachment and encroachment of large habitat patches in the affected area, destroying the effective habitat of species and ecosystems in the reserve, and posing a great threat to species and ecosystems in the reserve. Conservation of Biodiversity in Affected Areas
Many scholars have found that development and construction activities are the main factor leading to ecological damage in nature reserves. However, there is no set of quantitative and rapid indicators for the ecological impacts of different development and construction activities on objects in different types of nature reserves and to what extent. and methodology

Embodiment 1

[0134] Embodiment 1 of the present invention discloses a method for evaluating the ecological impact of a development and construction project in a nature reserve, such as figure 1 shown.

[0135] (1) Remote sensing identification method for nature reserve construction projects

[0136] The object-oriented classification method is based on the spectral and shape characteristics of remote sensing images, setting appropriate segmentation scale, spectral heterogeneity, shape heterogeneity and other parameters, segmenting the image, obtaining homogeneous objects, and then comprehensively analyzing the objects according to the classification objectives The spectrum, shape, texture and other characteristics of the object are classified and extracted. It is mainly divided into the following four steps:

[0137] 1) Multi-scale segmentation

[0138] Multi-scale segmentation essentially uses the least heterogeneity-based merging algorithm (FNEA algorithm) to segment the image into mu...

Embodiment 2

[0382] Embodiment 2 of the present invention discloses an ecological impact evaluation system for development and construction projects of nature reserves, including a remote sensing identification subsystem, a project extraction subsystem, an ecosystem protection area impact evaluation subsystem, and a wild animal protection area impact evaluation subsystem; Figure 9 shown.

[0383] Among them, the remote sensing identification subsystem is used to obtain remote sensing images; the project extraction subsystem includes: multi-scale segmentation module, information extraction module and protected area type judgment module; multi-scale segmentation module is used for multi-scale segmentation of remote sensing identification images; The information extraction module is used to extract the evaluation index parameters; the protection area type judgment module is used to judge the protection area type of the impact area to be evaluated; the impact evaluation subsystem of the ecosys...

Abstract

The invention discloses a method for evaluating the ecological influence of a development and construction project in a natural protection area. The method comprises steps of obtaining a remote sensing image of the natural protection area, carrying out remote sensing recognition on one construction project based on the remote sensing image, calculating each evaluation index for two different periods, obtaining specific evaluation indexes of the evaluation indexes of the two different periods, and calculating a specific index change value according to the two specific indexes; substituting the specific index change value into the ecological influence evaluation model to obtain an influence index, and judging the influence degree of the influence index through the influence index. The invention further discloses a system for evaluating the ecological influence of the development and construction project in the natural protection area. The system comprises a remote sensing recognition subsystem, a project extraction subsystem, an ecological system protection area influence evaluation subsystem and a wild animal protection area influence evaluation subsystem. According to the method, the influence strength evaluation on the development and construction activities of the natural protection area can be quantitatively and rapidly realized, the investment of manpower and material resources can be effectively reduced, and the economic benefit is relatively high.

Description

technical field [0001] The invention relates to the technical field of environmental protection, and more specifically relates to a method and system for evaluating the ecological impact of a development and construction project of a nature reserve. Background technique [0002] The establishment of nature reserves is an important basis for the protection of species habitats around the world, and it is also one of the most direct and effective measures to protect the biodiversity in habitats. Nature reserves can provide humans with the natural "background" of ecosystems. They are the natural storage banks of various natural ecosystems and wild species. They are the treasure and essence of my country's natural ecological environment. barrier and an important carrier for building a beautiful China. [0003] At present, although great achievements have been made in the construction of nature reserves in my country, with the continuous growth of my country's population and rapid...
