泰安市城区土地集约度的动态评价

以中心城市建成区范围内的土地为研究对象,结合泰安市的实际情况,以土地投入、产出和生态环境三个方面为切入点,设计了3个项目层(目标层、准则层和因子层),选择了11个指标因子(地均固定资产投入、地均铺装道路面积、地均从业人员总数、地均财政收入、地均消费品成交总额、地均GDP、人均GDP、人均城市用地、人均住房、绿化覆盖率和人均公共绿地),构建了评价指标体系.并采用多因素综合评价模型,计算了泰安市1990,2000和2007年三个时期的土地集约利用综合分值.结果显示,泰安市建成区的土地集约利用在土地投入、产出和生态环境等方面都有一定程度的提高,其中,不同的指标因子对于土地集约程度提高的贡献有显著的不同:固定资产投入、地均财政收入、地均GDP、人均GDP、人均公共绿地等指标因子的显著变化,为提高土地集约利用程度起到了积极的作用.而地均铺装道路、地均从业人员数、绿化覆盖率等指标因子变化不明显,没有起到应有的作用.

Dynamic evaluation of land use intensity in Taian city

An evaluation index system for the central area land in Taian city Shandong province was built, including three layers (Target, Criteria and Element Layers) and 11 indices (the investment in fixed assets, road paving, total employees, all government revenue, the total turnover of all consumer goods, GDP, per capita GDP, urban land use area per capita, per capita living space, green coverage, per capita public green land of a certain area).The integrated score of three different periods of land intensive use in 1990, 2000 and 2007 was calculated, using a multi-factor comprehensive evaluation model.The results showed that the intensive utilization of built-up areas land was increased in Taian.Some factors, such as investment in fixed assets, all government revenue, GDP, per capita GDP and per capita public green land, condributed significantly to the improvement of intensive utilization of land, while other factors, such as all road paving, employees, green coverage in a certain area, have not so significant contributions.
