迁西县城镇土地质量驱动力影响与潜力挖掘分析

城镇土地在各种驱动力的综合作用下，呈现出不同的发展规律。本文以迁西县为例，利用极值标准化法对迁西县8个建制镇各驱动力指标数据进行标准化处理后，依据各驱动力总分值对各驱动力影响效果进行分级。以城镇土地质量驱动力分析图层体系为基础，采用地理信息系统（GIS）技术在土地分等成果图基础上对驱动力影响图进行叠置，结果表明，各驱动力对土地质量影响效果明显程度及潜力挖掘空间有所不同，8个建制镇的土地供应潜力、基础设施等从挖掘潜力差到挖掘潜力较大4个标准均有分布，对土地质量影响明显；城镇区位从挖掘潜力适中到挖掘潜力大、城镇集聚规模从挖掘潜力较差到挖掘潜力较大3个标准均有分布，对土地质量影响较明显；区域经济发展水平集中于挖掘潜力适中与挖掘潜力较大、综合服务能力则集中于挖掘潜力较差与挖掘潜力适中2个标准，对土地质量影响不明显。驱动力空间影响差异的表现是城镇在该方面发展优劣的反映，其结果能够指导城镇建设。

ANALYSIS OF URBAN LAND QUALITY DRIVING FORCE EFFECTS AND POTENTIAL MINING IN QIANXI COUNTY

Urban Land shows a different development pattern under the combined effects of the driving forces. Taking Qianxi county as a case, this paper uses extreme standardized method to deal with the county's eight townships driving forces indicator data and classifies the driving forces effects according to the total scores. Based on a system of urban land quality driving forces analysis layers, superposition analysis has been done on the basis of the land classification map and the factor scores level layers using Geographic Information System (GIS) technology. The result shows that the effect degrees and mining potential space of driving forces to land quality are different. Land production potential and basic establishment influence the land quality most distinctly, and they distribute from the lowest mining potential to higher mining potential on 4 standards. Urban location and urban convergency scale influence the land quality more distinctly. Urban location distributes from mining potential moderate to the highest mining potential, and urban convergency scale distributes from lower mining potential to higher mining potential on 3 standards. Regional economy develop level and integration service ability don't influence the land quality distinctly. Regional economy develop level is in mining potential moderate and higher mining potential, and integration service ability is in lower mining potential and mining potential moderate on 2 standards.The different of driving forces spatial effects reflects the strength or weakness of the urban on this aspect, and can guide the urban construction.
