Arable land consolidation potential (ALCP) evaluation is an ex ante evaluation, the purpose of which is to select areas that are suitable for land consolidation projects and to support the decision-making processes of the LC Bureau. In this paper, ALCP is divided into two types – theoretical and practical. Theoretical ALCP represents the potential that can be fulfilled from a natural standpoint and has five main categories: (1) increase in available arable land area; (2) increase in agricultural productivity; (3) decrease in agricultural production costs; (4) improvement in the ecological environment; and (5) decrease in land property disputes as a result of ALC. Practical ALCP represents the potential that can be achieved. The transformation from theoretical into practical ALCP is affected by factors such as existing technology and farmer support. Moreover, in this paper an evaluation system for both theoretical and practical ALCP is established, with all evaluation indices having values between 0 and 1. The ALCP for the Daxing district of Beijing is evaluated based on statistical and field survey data, using GIS analysis and a fuzzy synthetic evaluation model.(Zhengfeng Zhang, Jinming Yan, Wenwu Zhao and Wei Zhao,SCI)

 

耕地整治潜力评价体系及其在中国的应用

 

摘要:耕地整治潜力评价属于预评价,其目的在于选择适合整治的项目区,从而为土地部门的决策提供支持。论文中将耕地整治潜力分为理论潜力和现实潜力两类。理论潜力是从自然角度出发衡量的潜力,包括有效耕地面积的增加、农业生产能力的提高、农业生产成本的降低、生态环境的改善和产权纠纷的减少。现实潜力代表了可以真正获取的潜力。自然潜力向现实潜力的转换会受到技术、经济发展、农户支持程度等诸多因素的影响。论文从耕地整治的理论潜力和现实潜力两个方面构建了评价体系,并将所有的评价指标量化到01之间。同时选择北京市大兴区,基于统计和调查数据,采用GIS分析和模糊综合评判的方法进行了实证。
