【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]:According to the spatial differentiation of land use benefit, the optimal allocation of regional resources can be realized. It is very important to judge the benefit of land use reasonably. The difference of land use type reflects the diversity of land use benefit. Therefore, this study selects Chaohu Basin, which has rapid development of social economy and urbanization, and sets up different evaluation index system according to the two types of agricultural land and construction land. By using the entropy weight TOPSIS model and the two-dimensional quadrant method, the comprehensive evaluation logic model of agricultural land use benefit and construction land benefit in Chaohu Lake basin are measured, and the land use benefit in the study area is comprehensively evaluated. The results showed that the benefit of agricultural land in the study area was relatively low, the benefit range was 0.074 ~ 0.7129, and the regional difference was significant. Luyang District, Baohe District, Changfeng County and Shucheng County belong to the higher level, Wuwei County, he County, Jin'an District are relatively low. The benefit value of construction land has not reached 0.100, the benefit value range is 0.048 7 ~ 0.918 4, the higher area is concentrated in Hefei City area, Feidong County, Changfeng County and so on adjacent to Hefei County, Chaohu City, Lujiang County, Hexian County, etc. Hanshan County, Jin'an District, Shucheng County is generally low. The number of evaluation units classified into four quadrant types in the study area is 41.5and 4. combining with the connotation of different types of quadrants, this paper puts forward the countermeasures and suggestions for improving the benefit of agricultural land and construction land for each district and county.
