新疆城市土地集约利用潜力时空变异分析

以新疆17个市城市土地利用现状的经济、社会、生态指标数据为依据,建立城市土地集约利用程度评价指标体系,运用多指标综合评价法,对2003~2006年间城市土地集约利用程度进行评价;以评价结果为样本点,以STATISTICA软件为手段,进行新疆城市土地集约利用区域性时空差异评价,得出时间和空间变化特征。结果表明:以2003~2006年间新疆17个市城市土地集约利用度评价结果为基础,通过时间变化趋势分析,通过时间变化趋势分析可以看出,新疆城市土地集约利用潜力在4年中变化不大,总体呈上升趋势。通过聚类分析结果可以看出,新疆城市土地集约利用在地域分布上空间特征十分显著,呈现出一个梯度:从东向西,城市土地集约利用水平在某种程度上呈下降趋势。这充分反映了城市土地集约利用的区域不平衡性和层次性。

Spatial-temporal Variance of Urban Land Use Intensity in Xinjiang

Based on land-use current economic data,social data and ecological data in seventeen cities of Xinjiang the system of the assessmental indictors was established.The intesification degree of urban land use from 2003 to 2006 was evaluated and analyzed by comprehensive evaluation method.The spatial temporal variation of urban land use intensity in Xinjiang was evaluated with STATISTICA software and the characters of spatial temporal variation were obtained.The results showed that the potential of urban land use intensity in Xinjiang during the four years was little,based on the evaluation results of the urban land use intensity of 17 cities in Xinjiang from 2003 to 2006.According to the spatial temporal variation analysis,the overall trend is upward.Through cluster analysis,results show that the characteristics of the space geographical distribution of the intensive use of urban land in Xinjiang is very significant,showing a gradient: From east to west,the level of the intensive use of urban land is also downward to some extent.This fully reflects the regional imbalance of urban land use intensity.
