地下水超采区种植结构调整下的生态补偿激励机制研究
Study on incentive mechanism for ecological compensation in the adjustment of planting structure in groundwater overdraft area
摘要
Abstract
In order to study the incentive mechanism for ecological compensation for effectively en-couraging farmers to take the initiative to participate in restricting groundwater extraction and solve the problems by farmers'negative participation in the implementation of restriction on groundwater extraction measures and the insignificant effect of agricultural measures on restric-ting groundwater extraction in recent years.An ecological compensation incentive model for re-striction on groundwater extraction is established by improving the functional value models of runoff regulation and water conservation,the model is applied to the accounting of ecological compensation incentive standard for restricting groundwater extraction,and a new ecological compensation standard is obtained by combining with the ecological compensation basic standard calculated by the cost analysis method.Taking Cheng'an County as an example,the concept of drought index and the groundwater exploitation coefficient are introduced to improve the func-tional value model for regulating runoff and water conservation.The drought index objectively reflects the precipitation and climate in the study area,while the groundwater exploitation coeffi-cient reflects the difference of over extraction on underground water in each township.The im-proved model calculates and determines the compensation of each pilot village in Cheng'an County fluctuating between 416 yuan and 634 yuan per mu in the pilot year.The addition of incentive mechanism makes the ecological compensation standard of areas restricted by groundwater extrac-tion more targeted and reasonable,providing a reference for realizing the sustainable advancement of underground water pressure mining work.关键词
