摘要
以北京市顺义区为例,利用1996,2002,2009年3期土地利用现状图及统计和调查数据,综合运用Mapgis6.5,Arcview3.3空间分析工具,SPSS11.5中空间聚类(Hierarchical Spatial Cluster)等方法,分两个时段研究建设用地扩展分异特征及驱动力因子结果。研究结果表明:城镇、交通及特殊用地扩展速度加快,农村居民点、独立工矿扩展速度趋缓;而新增建设用地来源涉及所有其他地类,其中耕地贡献最高,达61.40%。1996—2009年建设用地扩展形成了潮白河沿岸及以西向中高水平扩展,而东部扩展缓慢,其鲜明对比格局形成3个建设用地高水平扩展空间连续的集聚中心,分别是以西南部天竺、后沙峪、南法信为主的空港经济圈;西北部高丽营、赵全营为主正在迅速崛起的重点镇区域;以及潮白河上游北小营、南彩为中心的奥运商圈。高水平扩展区域的首要驱动力依次为人均纯收入、村镇企业地均产值、城乡收入差异;中水平扩展区域驱动力依次为城乡收入差异、人口密度;而低水平扩展区域的驱动力集中于村镇企业地均产值。
Based on the land utilization maps of 1996,2002,2009,this paper analyzed the spatial differentiation and resources of the construction land expansion and driving forces,with Mapgis6.5,Arcview3.3 and SPSS11.5,in two successive phases from 1996 to 2002,2002 to2009.The results showed that the expansion speed of townland,traffic land and special land use in the recent period was quicker than the early period,on the contrary,the rural residential area,independent land used for industry and mining was declining.The resources of the construction land expansion came from all the other land use types,and contributive rate of farmland was 61.40% that was the highest.The pattern that the expansion level of Chaobai riverfront and western district is higher,while the expansion level of eastern district is lower.The three cluster centers appeared were Tianzhu,Houshayu and Nanfaxin airport economic circle in southwestern area,major towns of Zhaoquanying and Gaoliying in northwestern area,and Olympic Business Circle in the middle and upper reaches of Chaobai River.The main driving forces of the high level expansion region were in sequence of per capita net income,output value per hectare of the enterprises of villages and small towns,urban-rural income disparity;the main driving forces of the middle level expansion region were in sequence of urban-rural income disparity,population density;the main driving force of the low level expansion region was urban-rural income disparity.
