Embodiment

[0040] The present invention will be described below with specific examples.

[0041] Step 1. Obtain the basic information on flood resource utilization of the project to be studied.

[0042] Basic data on flood resource utilization of projects to be studied, including project parameters, hydrological statistics in flood season, water resource bulletins, and statistical yearbooks.

[0043] Step 2: Build a risk assessment system for flood resource utilization in water diversion projects.

[0044] The criterion layer of the flood resource utilization risk evaluation index system for water diversion projects includes three types of risks: water storage project risk, water transfer project risk, and water lifting project risk. The index layer is composed of specific indicators contained in each type of risk. For water storage projects, Risk indicators mainly include lakes and reservoirs in the system; for water transfer projects, risk indicators mainly include rivers and channels...

Abstract

The invention discloses a method for evaluating the utilization risk of flood resources in a water diversion project, and belongs to the technical field of risk assessment for the utilization of flood resources in a water diversion project. It includes the following steps: Step 1, obtain the basic data of flood resource utilization of the project to be studied; Step 2, construct the flood resource utilization risk assessment system of the water diversion project; Step 3, determine the flood resource utilization risk assessment level and standard of the water diversion project; Fourth, calculate the flood resource utilization risk of the water storage project, water delivery project and water lifting project risk index; step five, couple the objective weight calculated by the entropy weight method and the projection pursuit method with the initial weight calculated by the analytic hierarchy process, Use the combined weighting method to calculate the index weight; step six, calculate the index membership degree through the conditional cloud generator; step seven, obtain the overall evaluation level. The invention provides a method for evaluating the utilization risk of flood resources in a water diversion project, which provides a basis for the safe utilization of flood resources in the water diversion project.

Description

technical field [0001] The invention belongs to the technical field of risk assessment of flood resource utilization of water diversion projects, and relates to a risk assessment method of flood resource utilization of water diversion projects based on a combined weight cloud model. Background technique [0002] In recent years, with the rapid development of social economy, the contradiction between supply and demand of water resources has intensified. The cross-basin water transfer project can alleviate the shortage of water resources to a certain extent, but water transfer is generally carried out during the non-flood season. If water transfer is also carried out during the flood season to make full use of flood resources, the problem of water resource shortage in my country can be effectively solved. Taking the east route of the South-to-North Water Diversion Project as an example, the amount of water coming in during the flood season is abundant every year. If the utiliz...
