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 tidal flat ecological restoration method and device. The method includes: obtaining remote sensing images of tidal flats, and extracting the spatial distribution of constituent elements of tidal flat landscape patterns according to the remote sensing images; the constituent elements of tidal flat landscape patterns include at least one of ecological sources, ecological corridors, and ecological nodes; establishing tidal flat landscape patterns model, and verified the tidal flat landscape pattern model according to the spatial distribution information of the tidal flat landscape pattern components, and obtained the influencing factors affecting the tidal flat landscape pattern; according to the influencing factors, an evaluation index set for evaluating the environment of the tidal flat ecological zone was established; the combination of evaluation indicators included At least two sets of one-to-one evaluation indicators and weights; according to the evaluation index set and tidal flat type, the corresponding artificial intervention restoration model is established, and the tidal flat ecology is processed according to the artificial intervention restoration model. This method can fully consider the overall landscape pattern of the tidal flat area, and improve the comprehensive restoration effect of the tidal flat as a whole.

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...
