1999年开始启动的“退耕还林(草)”工程是一项以植被重建为方法,以实现经济、资源、环境协调可持续发展为目的的生态系统恢复工程,工程的可持续性是影响其绩效的重要指标,如今影响退耕还林工程可持续性的重点已由农户参与工程转为对已有退耕成果的管护。通过构建不确定状态下,政府对林地管护的支付意愿函数与农户对林地管护的受偿意愿函数,求解符合帕累托改进的林地管护补贴标准取值区间;运用单向递增的多界二分选择询价法对陕北吴起县实地调研数据进行分析,揭示不同设定补贴标准下样本户对林地管护的选择偏好。在此基础上,运用希克斯等效变差模型,推导样本户在不同林地管护方式条件下的等效用点,并用福利计量方法测定满足农户受偿意愿的补贴标准最小值,从而得出基于农民意愿的补偿标准。
The “Conversion of Cropland to Forest and Grassland” project, started in 1999, is an ecosystem restoration project with the purpose of vegetation reconstruction as a method for achieving coordinated, sustainable development of economy, resources and environment. The sustainability of the project is Important indicators affecting their performance, and now the focus of the project that affects the sustainability of the conversion of farmland to forestry has been changed from farmers’ participation in the project to the management and protection of the existing achievements in returning farmland. By constructing the government’s willingness to pay for forest land management and the compensation willingness function of farmers for forest land management under uncertain conditions, the value interval for forest land management and maintenance subsidies in line with Pareto improvement is calculated. By using one-way increasing Based on the dichotomous method of inquiry, this paper analyzes the field survey data of Wuqi County in northern Shaanxi Province, revealing the preferences of sample households for forest management and protection under different set of subsidy standards. On this basis, using the Hicks equivalence model to deduce the equivalent points of sample households under the different management methods of forest land use and determining the minimum standard of subsidy that meets the compensation needs of farmers, Compensation rates based on farmers’ wishes.
