摘要:

土地整治是保障国家粮食安全、促进社会主义新农村建设、统筹城乡发展的重要平台和抓手,是解决当前我国经济发展和耕地保护之间矛盾的重大举措。基于改进的灰靶模型和改进的熵值法,从土地整治应具备资源经济的实力、保障粮食安全的能力、维护社会和谐的力度、促进环境友好的程度4个方面构建指标体系,评价江苏省土地整治的可持续性,为后续土地整治决策和管理提供参考依据。从评价结果来看,江苏省土地整治基本处于可持续状态,但区域间的差异较大,苏北明显好于苏中和苏南地区,其中徐州达到Ⅳ级高度可持续的全省最高等级;土地整治的单层面可持续性表明,全省土地整治保障粮食安全能力的可持续性均在Ⅱ级水平以上,但多数存在社会和谐与环境友好不可持续的问题。为了提升土地整治的可持续性,应将土地整治工作的重点向改善农民生产生活、防范社会和生态风险方向倾斜,建立相应的公众参与机制和风险管理体系

Abstract:

Land consolidation plays an important role in many aspects. First of all, it can be used to increase the acreage of arable lands to ensure national food security. Secondly, agricultural production conditions and farmers living standards can be improved through land consolidation, which promotes the construction of new socialist countryside. Thirdly, in the process of land consolidation, the public service facilities and living environment in rural areas can be improved, which balances the development between urban and rural at a certain extent. In addition, land consolidation is also the major measure to solve our countrys current contradiction between economic development and arable land protection. The purpose of this study is to provide reference for the policy decision and management of the subsequent land consolidation work. In this paper, the sustainability of land consolidation in Jiangsu province was evaluated through defining a comprehensive assessment index system, which included four aspects. Firstly, a certain amount of resources and economy are essential to safeguard the smooth implementation of the land consolidation. Secondly, the ability to ensure food security must be improved through the land consolidation. Thirdly, the effect of the land consolidation must be conductive to maintaining social harmony. Finally, it is essential to promote the friendly degree of environment, including the ability to withstand natural disasters and the governance situation of environment. The improved entropy method was employed to calculate the index weight in this paper. The whole evaluation result was calculated by the method of improved grey target model through adding the index weight, which was calculated by the method of improved entropy weight. The results indicate that the overall sustainability of land consolidation is in the level of general sustainable in Jiangsu province during the period of “Eleventh FiveYear”, but there are more obvious differences between different regions. In the three regions of Jiangsu province, the sustainability of land consolidation in the northern area was significantly better than that of the Central Area and South Area. Among all the cities, the sustainability of land consolidation in Xuzhou was the highest, which achieved Class IV highly sustainable level. From the single point of view, levels of the sustainability of the whole land consolidation to ensure food security capabilities were all above the Class II, indicating that the land consolidation work of Jiangsu province has made significant achievements in increasing the amount and improving the food production capacity of arable lands. However, the affections of the land consolidation in maintaining social harmony and promoting environmentfriendly were not sustainable in the majority of areas in Jiangsu province. It is concluded that, in order to enhance the sustainability of land consolidation in Jiangsu province, the emphasis of land consolidation work should be turned to improve farmers production modes and living standards. At the same time, preventing the social and ecological risks are also very important. Therefore, we should establish corresponding public participation mechanisms and risk management systems to promote the whole land consolidation work successfully
