基于功能区的城市建设用地集约利用研究——以西宁市为例

Study on Intensive Utilization of Urban Construction Land Based on Function Area——A Case Study of Xining City

以西宁市市区2008年建设用地数据为依据,选取评价指标体系,确定指标权重,构建综合评价模型,以样本片区作为功能区的代表,运用综合评价法测算出各功能区的土地利用集约度,并对评价结果进行了分析。结果表明:西宁市市区建设用地集约利用总体处于适度利用水平,建设用地集约利用面积为542.13 hm2,适度利用面积为5 546.56hm2,低度利用面积为2 094.99hm2;土地集约利用潜力主要集中在居住用地和工业用地上。

Based on the data of urban construction land of Xining City in 2008, the assessment index system was chosen, the index weights were decided and the integrative assessment model was established. Taking the sample plots as the representative function area, land use intensive degree of each function area was calculated out by the integrative evaluation method, and the evaluation result was analyzed. The results showed that the intensive level of urban construction land use was moderate in Xining City. The areas of land intensive, appropriate and low use were 542.13, 546.56, and 2 094.99 hm2, respectively. The potentiality of land intensive use was mainly concentrated in residential land and industrial land.
