    摘要:

    从土地利用强度、土地投入强度、土地的经济效益和生态效益4个方面筛选指标构建土地节约集约评价模型,利用主成分分析确定土地节约集约利用的评价指标,运用层次分析法确定各指标的评价权重并结合GIS强大的空间分析和计算能力对土地节约集约情况进行评价。案例分析结果表明,基于GIS的土地节约集约利用评价结果与普查结果基本吻合,运用该模型能够更好地分析土地资源利用状况,可以为土地利用规划提供数据资料支持和决策依据。

    Abstract:

    The indecies were selected from four aspects including the utilization intensity investment intensity, economic and ecological benefits,and the model of the economical and intensive utilization of land resources were established. The principal component analysis was used to determine the specific evaluation index and the analytic hierarchy process was used to determine the weight of each in-dex. By means of the spatial analysis and computing capability of the GIS the economical and inten-live utilization of land resources were evaluated. The evaluated result was similar to the census result which showed that the evaluation model could be used to analyze the status of land utilization and pro-vide data support and decision criterion for the plan of land utilization.
