基于PSR模型的水库移民集镇安置区土地集约利用评价研究

Research on the Evaluation of Intensive Land Use in Resettlement Area of Reservoir Resettlement Town Based on PSR Model

土地集约利用问题是土地科学的核心问题之一,而水库移民集镇安置区这一特殊地区的土地集约利用研究目前相对较少。通过构建PSR模型,对Z集镇移民安置区进行了土地集约利用评价。研究结果表明:Z集镇移民安置区土地利用不集约,属于粗放型用地模式,土地低效利用现象较为严重。进一步利用障碍因子分析法,找出了影响Z集镇移民安置区土地集约的主要四个障碍因子:单位面积商铺营业额、土地人口承载量、地均建设总投资额和移民人均收入。对于水库移民集镇安置区提出以下三点建议以提高土地集约利用:(1)加大招商引资力度,提高移民商铺单位面积营业额;(2)完善安置区基础设施建设,提升土地人口承载力;(3)加大后扶资金扶持力度,提高地均投资额。

Intensive land use is one of the core issues of land science,while the research on intensive land use in the special area of reservoir resettlement town is relatively less.Through the construction of PSR model,the intensive use of land in the resettlement area of Z market town is evaluated.The results show that the land use in the resettlement area of Z Town is not intensive,which belongs to the extensive land use mode,and the phenomenon of inefficient land use is relatively serious.Further,by using the obstacle factor analysis method,four main obstacle factors affecting the land intensity in the resettlement area of Z Market Town are found:the turnover of shops per unit area,the carrying capacity of land population,the total investment in land construction and the per capita income of reservoir resettlement.For the resettlement area of reservoir resettlement market town,the following three suggestions are put forward to improve the intensive use of land:①increasing investment attraction and the turnover per unit area of reservoir resettlement shops;②improving the infrastructure construction in the resettlement area and enhance the land population bearing capacity;③The government should increase the support of post support funds to increase the average land investment.
