摘要
[目的]测度江西省2001—2015年的耕地环境效率,以此来衡量耕地利用与环境协调发展程度,并提出相应的改进策略。[方法]基于江西省2001—2015年11个地级市耕地投入产出的面板数据,运用松驰模型(slack-based model)方向性距离函数测度耕地环境效率。[结果](1)总体来看,江西省耕地利用与环境处于较为协调发展阶段,协调发展呈现"上升—下降"趋势;(2)各地市耕地利用与环境协调发展呈现出不同的状态和趋势。赣州市和九江市常年处于极不协调发展状态,是政府着力监管的重点区域。(3)各地市耕地利用与环境协调发展改进的潜力主要在于非期望产出的减少和耕地投入冗余的降低,且改进策略存在地区差异。[结论](1)提高耕地利用效率,减少耕地污染,改善耕地质量,倚重技术效率与技术进步的"内涵式"耕地利用模式转变。(2)设计和完善相关针对耕地面源污染薄弱环节的政策。(3)探索耕地休养生息制度。(4)各地市应有侧重地促进耕地利用与环境协调发展,并加强地市间的交流与合作。
[Objective]This paper measured the environmental efficiency of cultivated land in Jiangxi Province from 2001 to 2015 in order to judge the degree of coordinated development of cultivated land use and environment,and to propose corresponding improvement strategies.[Methods]Based on the panel data of farmland inputs and outputs of 11 prefecture-level cities in Jiangxi Province from 2001 to 2015,the environmental efficiency of cultivated land was measured by using slack-based model directional distance function.[Results]①The utilization of cultivated land use and the environment in Jiangxi Province was in a relatively coordinated development stage,and the coordinated development presented a“rising-falling”trend.②The development of cultivated land use and environment in different cities showed different statues and trends.Ganzhou City and Jiujiang City were in an inconsistent development all the year round,and they were the key areas for government supervision.③The potential of coordinated development and improvement of cultivated land use and environment in different cities mainly relied on the reduction of non-expected outputs and the redundancy of cultivated land inputs,and the improvement strategies were different among vary regions.[Conclusion]①The efficiency of cultivated land use can be improved,the pollution of arable land can be reduced and the quality of cultivated land can be improved,by transforming cultivated land model to connotative model based on technical efficiency and technological progress.②The related policies need to be made to solve the land source pollution issues.③Cultivated land recuperation and rest system need to be explored.④Different solutions should be focused on promoting the coordinated development of cultivated land use and environment in different cities,and strengthen exchanges and cooperation between cities.
