中文摘要:
      依据土地利用效益空间分异,能够实现区域资源优化配置。合理判定用地效益显得至关重要。土地利用类型差异化而体现用地效益多元化。为此,本研究选取社会经济及城镇化快速发展的巢湖流域,按照农用地和建设用地两大用地类型,差异化构建不同评价指标体系,采用熵权-TOPSIS模型与二维象限法构建的农用地–建设用地效益综合评判逻辑模型,测度了巢湖流域农用地效益和建设用地效益,以及综合评判了研究区的用地效益。结果表明:研究区农用地效益整体较偏低,效益值范围0.074 0 ~ 0.712 9,区域差异显著,庐阳区、包河区、长丰县、舒城县属于较高级别,无为县、和县、金安区相对较低,效益值均尚未达到0.100 0;建设用地效益区域差异悬殊,效益值范围0.048 7 ~ 0.918 4,较高区域集中于合肥市辖区及肥西县、肥东县、长丰县等紧邻合肥县域,巢湖市、庐江县、和县、含山县、金安区、舒城县普遍较低。研究区归入到4个象限类型的评价单元数,依次为4、1、5、4个,结合不同类型象限内涵,本文分别针对每个区县提出了农用地和建设用地的效益提升对策和建议。
Abstract:
      The optimal allocation of regional resources can be realized according to spatial differentiation of land use benefit, which is very important to reasonably determine land use benefit. The difference in land use type reflect the diversity of benefit. This study selected the agricultural land and construction land as two major land use types in the Chaohu Lake Basin with the rapid development of social economy and urbanization, constructed different evaluation index system according to the differentiation, constructed the evaluation logic models of the comprehensive benefits of agricultural land and construction land, respectively, calcuated and comprehensively assessed the use benefits of agricultural land amd construction by using Entropy Weight, TOPSIS Model and two dimensional quadrant method. The results showed that the use benefit of agricultural land was low overall, ranged from 0.074 0 to 0.712 9, exitsed significant regional differences, Luyang District, Baohe District, Changfeng County and Shucheng County belonged to the higher value regions, while Wuwei County, He Xian County and Jin’an District to lower value regions with the benefit lower than 0.100 0; The use benefit of construction land also existed significant regional differenes, ranged from 0.048 7 to 0.918 4, the higher value regions included Hefei City and adjacent Feixi County, Feidong County and Changfeng County, while the lower value regions included Chaohu City, Lujiang County, Hexian County, Hanshan County, Jin’an District and Shucheng County. The numbers of evaluation units classfied into the four quadrant types were 4, 1, 5 and 4, respectively. With the combination of the connotation of different quadrant types, the countermeasures were proposed for in each county or district for promoting the use efficiency of agricultural land and construction land.
