Abstract

The invention provides an integrity assessment technology for a three-dimensional physical habitat of an urban river. The technology comprises the following steps of (1) constructing an integrity assessment index system for the three-dimensional physical habitat of the urban river; (2) carrying out field investigation according to an index calculation method in the step (1); (3) constructing an integrity assessment standard system for the three-dimensional physical habitat of the urban river according to a field investigation result in the step (2); and (4) utilizing a modified gray clustering analysis method to carry out integrity assessment on the three-dimensional physical habitat of the urban river. The method adopted in the integrity assessment technology is suitable for integrity assessment of the three-dimensional physical habitat of the urban river, is helpful for recognizing reaches with the poor physical habitat of the urban river and index factors for causing the poor integrity of the physical habitat of the urban river and is applicable to the fields of environmental sciences and ecological restoration.

Description

technical field

[0001] The patent of the present invention relates to the field of ecological restoration, and is a technology that can be used for the integrity evaluation of physical habitats of urban rivers. According to the characteristics of strong human disturbance in urban rivers, this technology selects 10 evaluation indicators from the three dimensions of horizontal integrity, vertical integrity and vertical integrity, and constructs a three-dimensional physical habitat integrity evaluation index system for urban rivers; The highest score of each indicator in the monitoring point is used as a reference value to construct the evaluation standard system of urban river physical habitat integrity; the traditional gray clustering evaluation method is improved by introducing information entropy, and the improved gray clustering evaluation method is used to evaluate the integrity of urban river physical habitat. sexual development evaluation.
