Embodiment 1

[0152] A river health assessment method suitable for sediment-rich rivers. This method starts from data collection, goal setting, current situation investigation, system analysis, and comprehensive evaluation to build a relatively systematic and comprehensive health assessment index system for sediment-rich rivers. , with reference to the relevant regulations of the Ministry of Water Resources, research and establish river health assessment methods, index scoring methods and assessment standards, and design an indicator system for the health assessment of rivers and lakes with high sediment content; specifically, the following steps are included:

[0153] Step 1. Determine the mandatory indicators for the evaluation indicator system

[0154] According to the relevant regulations of the Ministry of Water Resources, the evaluation index system of pilot rivers includes 12 mandatory indicators, which are described in detail as follows:

[0155] (1.1) Indicators at the criterion la...

Abstract

The invention relates to a river health assessment method suitable for a sediment-laden river, This method includes: starting from the aspects of data collecting, target setting, current situation investigation, systematic analysis and comprehensive evaluation, constructing a systematic and comprehensive health evaluation index system of sediment-laden rivers and lakes; referring to relevant regulations of the ministry of water resources, studying and establishing the river health evaluation method, index scoring method and evaluation standard, and designing the health evaluation index systemof sediment-laden rivers and lakes; evaluating the health status of sediment-laden rivers by calculating 12 compulsory indexes and 4 self-selected indexes in 5 criterion layers of hydrology, water resources, physical structure, water quality, biological and social service function. The invention constructs a river health evaluation index system suitable for the characteristics of sediment-laden rivers and carries out the research on the health evaluation of sediment-laden rivers according to the present situation that the research on the theory and method of river and lake health evaluation inChina is relatively backward and there is no more complete evaluation framework.

Description

technical field [0001] The patent of the invention belongs to the technical field of river ecosystem protection, and specifically relates to a river health assessment method suitable for rivers with many sediments. Background technique [0002] Rivers are the source of life. The origin of human beings and the development of human civilization are closely related to rivers. Rivers are not only the form of water resources that can be exploited and utilized by humans, but also the living environment for tens of thousands of aquatic organisms in rivers. Rivers The health of human beings is the material basis and guarantee for human survival and economic development. Due to the double influence of natural factors and human factors, there are currently four major problems in China's rivers: "water shortage, water excess, dirty water, and muddy water". Some silt-rich rivers are in an unhealthy or seriously unhealthy state; China's soil erosion is serious. For silt-rich rivers, the ...
