Embodiment 1

[0028] figure 1 The implementation process of the tidal flat ecological restoration method provided by Embodiment 1 of the present invention is shown, and the details are as follows:

[0029] Step S101, acquiring remote sensing images of tidal flats, and extracting the spatial distribution of constituent elements of the tidal flat landscape pattern according to the remote sensing images.

[0030] Wherein, the composition elements of tidal flat landscape pattern include at least one of ecological sources, ecological corridors and ecological nodes. The tidal flats mentioned in this embodiment may be coastal tidal flats, river tidal flats or lake tidal flats.

[0031] Specifically, multi-spectral remote sensing images of tidal flats in different periods and satellite remote sensing images of night lights can be collected, and then a comprehensive database of tidal flat ecological restoration can be established based on ArcGIS on the basis of in-depth analysis of the relevant dat...

Abstract

The invention is applicable to the field of environmental technology and provides a mudflat ecology restoration method and device. The method comprises the steps that a remote sensing image of a mudflat is acquired, and spatial distribution of mudflat landscape pattern constitution elements is extracted according to the remote sensing image; the mudflat landscape pattern constitution elements include at least one of an ecological source region, an ecological corridor and ecological nodes; a mudflat landscape pattern model is established, and the mudflat landscape pattern model is verified according to spatial distribution information of the mudflat landscape pattern constitution elements to obtain impact factors impacting a mudflat landscape pattern; an evaluation index set for evaluating a mudflat ecotope environment is established according to the impact factors, wherein the evaluation index set comprises at least two groups of evaluation indexes and weights in one-to-one correspondence; and a corresponding manual intervention restoration model is established according to the evaluation index set and a mudflat type, and mudflat ecology is treated according to the manual intervention restoration model. Through the method, the overall landscape pattern of the mudflat region can be fully considered, and the comprehensive remediation effect on the whole mudflat is improved.

Description

technical field [0001] The invention belongs to the field of environmental technology, and in particular relates to a tidal flat ecological restoration method and device. Background technique [0002] Existing research on ecological restoration and reconstruction of coastal zones (including coastal tidal flats) is mainly carried out for a certain type of ecosystem in a local area (such as river estuaries, mangroves, and coral reefs). Coastal habitat restoration is an early measure to restore degraded coastal ecosystems and restore biological resources. In the 1920s and 1930s, the United States proposed the concept of coastal habitat restoration, and its National Oceanic and Atmospheric Administration Habitat Restoration Center proposed strategies for coastal and estuary habitat restoration, forming a framework for coastal and estuary habitat restoration. Since then, the concept of "coastal buffer zone" has been proposed in many international environmental forums and confere...
