基于机会成本的宁夏中南部调水工程水源区生态补偿标准研究
Study on ecological compensation standards in the water source area of the water diversion project in Central and Southern Ningxia based on opportunity cost
摘要
Abstract
In order to consider the interests of both parties participating in the water diversion project and to calculate a more appropriate ecological compensation standard,this paper takes the water source area of Jingyuan County of the water diversion project in central and southern Ningxia as an example,builds the ecological compensation model for water source areas based on opportunity cost.Considering that the economic growth of the water-receiving area has a significant role in promoting the development and functioning of the ecological compensation mechanism,the model is used to not only calculate and analyze the direct cost and opportunity cost of ecological compensation,but also to apply the principal component analysis(PCA)to quantify the actual payment capacity of the receiving area,and using the measured ecological compensation coefficient to correct the ecological protection cost from 2017 to 2020.The results showed that:The amount of ecological compensation that Jingyuan County can obtain in the initial stage of compensation,considering the economic payment capacity of the water-receiving area,is 76.2394—175.8568 million Yuan.The direct cost of ensuring the safety of water transfer and repairing environmental damage caused by water diversion accounts for the largest proportion in the study area,especially in water conservancy construction and forestry construction,according to an analysis of the direct cost and opportunity cost of ecological compensation in the Jingyuan water source area.The decrease in industrial opportunity cost and the shift in agriculture opportunity cost loss in Jingyuan County amply demonstrate the necessity of taking steps to optimize the forest and grass industry and energetically grow the green light industry sector.关键词
