| 摘 要： | 开展土地集约利用研究,提高集约利用程度,缓解城市建设用地的需求与有限土地供给的矛盾,是目前迫切需要解决的问题。运用灰色系统理论,以地均国内生产总值(GDP)预测为例,建立了南通市地均GDP预测的灰色模型,并预测了2008~2020年南通市的地均GDP。利用灰色关联度分析,探讨了南通市地均GDP受地均固定资产投资、地均建设用地非农产值、建设用地增量、建设用地面积影响的程度,并提出了该市土地集约利用的调整方向。灰色系统理论的应用可为今后土地集约利用评价提供一种新的研究思路,对同类研究具有一定的借鉴作用。 |

| Abstract: | Such problems needed to be resolved immediately as carrying out potential evaluation research into intensified utilization of urban land,improving standard of urban land's intensified utilization,and solving the contradiction between the demand for urban construction land and limit of land supply.Taking GDP per area forecast for example,the Gray model on GDP per area forecast in Nantong City was established based on Gray System Theory,and the GDP per area in Nantong City in 2008-2020 were forecasted.Gray relational grade analysis was used to discuss the the effect of the investment in fixed assets per area,the non agricultural output per area,the area of construction sites and the increased area of construction sites on GDP per area.And the direction of intensive use of land was put forward.Gray relational grade analysis could provide new idea for the evaluation of intensive use of land and could be used for reference to the similar study. |
| Keywords: | Gray forecasting model Intensive use of land GDP per area forecast Gray relational grade analysis |
