Social and economic benefit accounting method for river source arid region water resource potential tapping and efficient utilization effects

Abstract

The invention provides a social and economic benefit accounting method for river source arid region water resource potential tapping and efficient utilization effects, which comprises the following steps: selecting indexes to establish a judgment matrix by using a matter-element analysis theory, dividing a classic domain and a node domain according to the judgment matrix, and taking the correlation degree as a data source for qualitatively evaluating social and economic benefits; constructing a C-D production function adapting to river source arid region characteristics, completely converting different elements into solar energy through the energy value theory; if colinearity exists between the different elements, using ridge regression to solve the problem of colinearity between the elements, and finally solving the inter-year water resource benefit specific value according to the obtained function to serve as a quantitative evaluation result; analyzing water resource potential tapping and efficient utilization conditions of the research area, and analyzing input and output to obtain social and economic benefit accounting results of the research area. According to the method, the index weight is calculated by using the AHP and the entropy weight method, the subjective influence is overcome, and the accidental problem of single evaluation is avoided by combining the qualitative method and the quantitative method, so that the accounting result is more accurate.

Description

technical field [0001] The invention relates to the field of water resources utilization, in particular to a method for calculating social and economic benefits of water resources potential tapping and efficient utilization in the arid area of ​​Heyuan. Background technique [0002] In recent years, with the continuous improvement of productivity, the research on tapping the potential and efficient utilization of water resources in the arid area of ​​Heyuan has continued to deepen, which has alleviated the pressure on water resources faced by the region to a certain extent. The main way to tap the potential of rainfall runoff in the arid area of ​​Heyuan is to use artificial rainfall enhancement technology to increase the probability and amount of rainfall by supplementing certain necessary conditions for the formation of rainfall, so as to achieve the effect of increasing rainfall; resource utilization efficiency. Due to the soil characteristics of the region, field leakag...

AI Technical Summary

Problems solved by technology

For example, the amount of data required by the general equilibrium theory is too large, and the amount of data is insufficient for the Heyuan area and the arid area. Using this method is not conducive to obtaining accurate results; the shadow price is the relationship between water resources and social and economic benefits under the scarcity situation. Explain that the usage is single; although the fuzzy mathematics method is very convenient to use, the determination method of the index weight is not uniform, which may easily lead to uncertainty in the results; when the emergy theory is used to calculate the emergy conversion rate, the amount of energy in different regions Values ​​vary and are not representative; marginal opportunity cost has no relativity in benefit accounting and the research is relatively one-sided
