Watershed scale river physical habitat evaluation method, system, medium and device

Abstract

The invention provides a watershed scale river physical habitat evaluation method, system, medium and device. The method comprises the following steps: constructing a watershed scale river physical habitat evaluation standard system; calculating river landform data and river network water system structure data based on the river basin scale river physical habitat evaluation standard system to obtain a calculation result; generating a river habitat index evaluation standard based on the calculation result; and evaluating the watershed scale physical habitat by using the entropy weight matter-element model. The basin scale river physical habitat evaluation method, system, medium and device are used for guiding and evaluating the evaluation and recovery work of the basin scale river physical habitat.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a method, system, medium and device for assessing river basin-scale physical habitats. Background technique [0002] River habitat is the comprehensive environment of river aquatic animal and plant living habitat and adjacent environment. It provides the natural connection between the natural environment and various organisms, and is an important indicator for evaluating the health of rivers. Urban rivers are the only complete ecosystems in cities. Countries such as the United Kingdom, the United States, and Australia have successively developed a variety of distinctive river habitat assessment models based on the actual conditions of their river habitats. In the past two decades, in the face of the prominent degradation of the river ecological environment, domestic scholars have also started empirical research on river habitat assessment, but in general, domestic ...
