Embodiment

[0050] The present invention will be described below with specific examples.

[0051] The Weishan Yellow River Diversion Line and the Panzhuang Emergency Yellow River Diversion Line have been connected in the first phase of the Lubei Main Canal, which is ready to deliver water to Hebei Province and Tianjin City. Before the implementation of the second phase of the project, take joint dispatch management measures and add a small number of engineering measures, make full use of the water supply capacity of the first phase of the project and the water supply potential throughout the year, and extend the emergency water supply to the north to the three provinces (municipalities) of Beijing, Tianjin and Hebei , to achieve rational use of water resources, and to maximize the benefits of the first phase of the project. Taking the Beijing-Tianjin-Hebei region as an example below, a method for quantifying the benefit of a regional ecological water supply system provided by the inventio...

Abstract

The invention discloses a method for quantifying the benefit of a regional ecological water supply system, belonging to the technical field of quantifying the benefit of the regional ecological watersupply system. The method comprises the following steps: step 1, acquiring the research area data; 2, drawing an energy map of the ecological water supply system in the region; 3, establish an energyanalysis table; 4, forming an input-output table of that ecological water supply system; 5, calculate that ecological water supply benefit by use the water supply benefit apportionment coefficient method; 6, analyze and evaluating that ecological water supply system. The invention provides scientific basis for formulating correct system management control measures and development strategies, and guides the benign operation and sustainable development of the ecosystem.

Description

technical field [0001] The invention discloses a method for quantifying the benefit of a regional ecological water supply system, in particular to a method for quantifying the benefit of a regional ecological water supply system based on an emergy analysis method, and belongs to the technical field of quantitative research on the benefit of a regional ecological water supply system. Background technique [0002] In recent years, with the rapid development of social economy, the contradiction between supply and demand of water resources has intensified. Due to the serious shortage of water resources and the phenomenon of occupying ecological water supply for production requirements, the ecological environment of our country has been damaged to varying degrees. Ecological water supply refers to the virtuous cycle of the watershed ecosystem and the development and balance of the system itself within a certain time and space when carrying out water resources development activiti...
