Embodiment Construction

[0033] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with the accompanying drawings and specific examples. Such as Figure 2-5 As shown, the present invention takes the Tuhai River as the research object, uses the ecological footprint method to study the related water resource ecological footprint, and calculates and analyzes the water resource carrying capacity and ecological deficit.

[0034] Step 1: Calculation method of water resources carrying capacity

[0035] According to the classification of water use characteristics, the water resource accounts are divided into five secondary accounts: domestic water footprint, agricultural water footprint, industrial water footprint, urban public water footprint, and ecological environment water footprint. Among them, domestic water includes urban domestic water and rural domestic w...

Abstract

The invention discloses a basin water resource carrying capacity evaluation method based on an ecological footprint model. A water resource is taken as a research object, an ecological footprint method is used for involved water resource ecological footprints including domestic water footprints, town public water footprints and industrial water footprints, the agricultural water footprints are researched, and computational analysis is carried out on water resource carrying capacity and ecological deficit. According to the method, the agricultural acreage is appropriately reduced, the utilization efficiency of water resources is improved, and the method is significant for sustainable development of water resources.

Description

technical field [0001] The invention relates to a comprehensive evaluation method for sustainability, in particular to an evaluation method for water resource carrying capacity of a river basin based on an ecological footprint model. Background technique [0002] As an important natural resource, water resources are closely related to regional economic development and people's production and life. With the rapid development of social production and the improvement of living conditions, the sharp increase in industrial and agricultural water use and population expansion have led to water resource shortages, water environment deterioration and ecological imbalance, which have seriously threatened the survival and development of human beings themselves; water resource shortage and water pollution The increasingly serious situation will seriously restrict the development of the region. In order to fundamentally solve the contradiction between water supply and demand and human n...
