基于时空角度的广东省耕地占补平衡绩效评价

Performance evaluation of cultivated land occupation compensation balance policy in Guangdong Province from the perspective of time and space

随着社会经济的迅猛发展,我国的城市化水平不断加快,城市面积不断扩张,耕地资源面临着被过度占用的风险,耕地的锐减对国家的粮食安全及生态环境产生了负面影响。在耕地面积逐渐减少的背景下,国家制定了耕地占补平衡相关政策,以期保护耕地、促进土地资源的高效利用以及维护国家粮食安全和社会稳定。本研究从时间角度对广东省2000—2016年耕地占补平衡政策绩效进行评价,从空间的角度通过构建PSR模型对广东省21个市2011—2015年耕地占补平衡政策绩效进行评价。结果显示,在时间维度上2000—2016年政策绩效呈阶段性上升的特点,2016年上升至最大值。在空间维度上,广东省耕地占补平衡政策绩效存在明显的区域差异,粤东、粤西地区在落实耕地占补平衡政策方面取得较好的绩效成果,其中粤西沿海和粤西北山区实施绩效最好,而珠三角平原地区实施绩效较差。最后,在广东省耕地占补平衡政策绩效评价的基础上,从缓解耕地占补平衡压力、加大惠农力度、耕地提质、引入社会资金等四个方面提出合理有效的建议。

With the rapid development of social economy,the urbanization level of our country is accelerating,the urban area is expanding,and the cultivated land resources are facing the risk of over occupation.The sharp decrease of cultivated land has a negative impact on the national food security and ecological environment.Under the background of the gradual reduction of cultivated land area,the state has formulated policies related to the balance of cultivated land occupation and compensation,in order to make contributions to the protection of cultivated land,the promotion of efficient use of land resources,and the maintenance of national food security and social stability.This study evaluated the policy performance of cultivated land occupation and compensation balance in Guangdong Province from the perspective of time from 2000 to 2016,and evaluated the policy performance of cultivated land occupation and compensation balance in 21 cities of Guangdong Province from 2011 to 2015 by constructing PSR model from the perspective of space.The evaluation results showed that,in the time dimension,the policy performance revealed the characteristics of periodic increase from 2000 to 2016,and the increase in2016 was the hightest.In the spatial dimension,there were obvious regional differences in the performance of cultivated land occupation and compensation balance policy in Guangdong Province.Eastern and western Guangdong had achieved good results in the implementation of cultivated land occupation and compensation balance policy,among which western Guangdong coastal area and northwest Guangdong mountainous area had the best performance,while the Pearl River Delta plain area had poor performance.Finally,based on the performance evaluation of cultivated land occupation and compensation balance policy in Guangdong Province,reasonable and effective suggestions are given from four aspects:alleviating the pressure of cultivated land occupation and compensation balance,benefiting agriculture policy,improving the quality of supplementary cultivated land,and introducing social funds into the response mechanism of cultivated land occupation and compensation balance.
