Abstract

The invention provides a method for uniform measurement and analysis of the positive and negative benefits of water use in agricultural ecological economic systems based on emergy. The method comprises the following steps: (1) constructing the energy system diagram of agricultural ecological economic systems; (3) Carry out the emergy analysis of the positive benefits of water use in the agricultural ecological economic system; (4) Carry out the emergy analysis of the negative benefits of water use in the agricultural ecological economic system; use the analysis method of the present invention to realize the water use of the entire agricultural ecological economic system The unification of the dimensions of positive and negative benefits can establish an objective evaluation standard for agricultural water use through the comparative analysis of positive and negative benefits of water use, so as to reduce agricultural water waste, improve water use efficiency, achieve the purpose of water conservation, and realize the goal of water conservation in the entire region. Comprehensive benefit maximization.

Description

technical field [0001] The invention belongs to the technical field of water resources economy, and relates to an analysis method for the positive and negative benefits of water use in an agricultural ecological economic system, in particular to a unified measurement and analysis method for the positive and negative benefits of water use in an agricultural ecological economic system based on emergy analysis. technical background [0002] Through agricultural production, human beings intervene and utilize natural ecosystems to form the most extensive and vital material cycle and energy conversion process. Water is the material basis necessary for the growth of all crops, the lifeblood of agriculture, and the lifeblood of the entire national economy and human life. Agricultural production mainly utilizes the chemical energy of water, which is converted into organic chemical energy through the photosynthesis and respiration of crops, so as to provide human beings with agricultu...
