Embodiment Construction

[0089] The evaluation method for urban river ecological restoration of the present invention will be described in further detail below.

[0090] The evaluation method operating steps of urban river course ecological restoration of the present invention are as follows:

[0091] (A) The evaluation system of urban river ecological restoration is established into a three-level evaluation system structure, and the ecological evaluation of urban rivers is regarded as a large system, and the second-level indicators are the criterion layer, which is divided into river water quality and ecosystem health 1. The ecological landscape is suitable for the three subsystems; the third-level indicators are a number of specific indicators, which can directly reflect the overall status of each subsystem. The third-level indicators and the weights of each indicator are shown in Table 1;

Abstract

A method for evaluating ecological restoration of a city watercourse is characterized by comprising the following steps that (A) a city watercourse ecological restoration evaluating system is established to be of a three-level evaluation system structure, the ecological restoration evaluating system serves as a large system, a second-level index serves as a rule layer is divided into three sub-systems of watercourse water quality condition, ecological system health and ecological landscape suitable degree, and third-level indexes represent a plurality of specific indexes and can directly reflect the total situation of each sub-system; (B) an evaluation step is executed: (B1) the watercourse to be evaluated is determined, and a sampling station is designed according to the length of the watercourse; (B2) sample acquisition and analysis are performed including (B21) physical and chemical indexes of water quality, (B22) ecological index (B23) ecological landscape suitable degree index; (B3) evaluation results are analyzed; (B4) the ecological health situation of the watercourse is judged. The method has the important significance on scientific evaluation on the ecological treatment effect of the watercourse and consolidation of ecological treatment results of the watercourse and is suitable for application in evaluation on the ecological restoration of the city watercourse.

Description

Technical field: [0001] The invention relates to an urban river ecological restoration, in particular to an evaluation method for urban river ecological restoration. Background technique: [0002] "The prosperity of ecology leads to the prosperity of civilization, and the decline of ecology leads to the decline of civilization." In April 2015, the State Council issued the "Water Pollution Prevention and Control Action Plan", which outlined a clear roadmap for the construction of water ecological civilization. The ecological restoration of urban rivers in my country started in the late 1990s. After the 18th National Congress of the Communist Party of China, the scale of ecological governance of rivers has increased to an unprecedented height. However, the current research and practice of river ecological restoration mostly focus on the water quality of polluted water bodies. Improvement, instead of emphasizing the stability of the restoration of the structure and function of ...
