摘要
就农村居民点整理潜力转化为耕地的经济限制性进行研究。从经济可行性评价入手,构建指标体系,采用多指标综合评价法、层次分析法与专家咨询法,测算研究区经济适宜性评分,确定研究区农村居民点整理潜力转化为耕地的经济限制性,得出各区县整理潜力转化为耕地的经济限制性修正系数。研究结果表明,天津市农村居民点整理潜力转化为耕地的经济限制性可分为3个类别:(1)无经济限制性区县,1≥a经≥0.6,包括西青区、北辰区、东丽区3个区县;(2)有一定经济限制性区县,0.6>a经≥0.3,包括塘沽区、津南区、武清区、宁河区、汉沽区、大港区6个区县。(3)经济限制性较大区县,0.3>a经≥0,包括蓟县、宝坻区、静海区3个区县。各区县农村居民点整理潜力转化耕地的经济限制性在多经济因素影响下差别很大。
This paper studied the economic restrictive correction of cultivated land which is transformed from the potential consolidation of rural residential area. By evaluation of economic feasibility, the study constructed indexes system and adopted multi-index comprehensive evaluation method, AHP, the method of literature and consulting with experts, and obtained the scores on economic adaption of each studying area and determined the coefficient of economic restrictive correction on the transformation of cultivated land from rural residential area consolidation. The results showed that Tianjin＇s districts can be divided into three categories on the basis of the economic restriction for cultivated land potential transforming from the consolidation of rural residential area：（1） no economic restriction district, 1≥a（coefficient of economic restrictive correction）≥0.6, included three districts： Xiqing District, Beichen District and Dongli District;（2）certain economic restriction district,0.6a≥0.3, included six districts： Tanggu Distircrt, Jinnan District, Wuqing District, Ninghe District, Hangu District and Dagang District;（3）large economic restriction district, 0.3a≥0, included three districts： Ji District, Baodi District and Jinghai District. The economic restriction of Tianjin districts makes a great difference on cultivated land transforming potential under many economic influence factors.
