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
