Abstract

The invention relates to a basin giant system state analysis method and device, and the method comprises the steps: determining the boundary and structure of a basin giant system, dividing the basin giant system into a river subsystem, an ecological environment subsystem and a human economy subsystem, and building a basin comprehensive evaluation index system; collecting and cleaning index data of all evaluation indexes in the comprehensive evaluation index system within a preset time period; dividing the indexes into positive entropy change indexes and negative entropy change indexes based on a basin comprehensive evaluation index system and index characteristics, respectively calculating total entropy values, and calculating dissipation structure indexes of the giant system by utilizing a Brusser model; and calculating the basin development index of the giant system according to the dissipative structure index so as to evaluate the basin development quality. Through the technical scheme, a river control decision theory taking the basin development index as a decision basis is provided, the basin giant system evolution state and development quality are comprehensively evaluated, and technical support is provided for comprehensive treatment, system treatment and source treatment of the Yellow River basin.

Description

technical field [0001] The present disclosure relates to the technical field of watershed management, in particular to a state analysis method and device for a giant watershed system. Background technique [0002] Harnessing the Yellow River has always been a major event for the Chinese nation to stabilize the people and rejuvenate the country. After the founding of New China, the management, development, protection and management of the Yellow River have achieved world-renowned achievements, and achieved remarkable economic, social and environmental benefits in water and sediment control, ecological protection, flood control and disaster reduction, water and soil erosion, and water resource utilization. It supports the sustainable economic and social development of the basin. However, the Yellow River is a river that is good at silting, clearing, and migrating. The characteristics of "less water and more sand, and uncoordinated relationship between water and sand" determin...
