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.
