| 摘 要： | 以2005 年深圳市主要公路沿线6 类城市建设用地为研究对象, 基于景观格局指数和空间数据挖掘(SDM) 中的空间关联规则, 研究不同缓冲带内其建设用地单一类型、相邻类型及组合类型的空间聚集特征。结果表明: 主要公路两侧以工业用地为主, “三来一补”、“三 资”企业为主体的外向型乡镇企业加快了特区外的农村城市化进程; 城市公共设施、教育和医疗卫生用地缺乏, 一定程度上妨碍了城市经济功能的协调; 单一类型建设用地景观分异特征趋向于距公路越远, 出现频率越小, 且随着逐渐远离公路线出现了若干次级集中区, 距公路500-1000 m 可作为识别该次级中心的特征带; 两类建设用地之间的空间邻近分布特征表 明, 以各类建设用地为中心与其他类建设用地在公路线附近均表现邻近, 沿线附近和较远距离上随工业用地出现峰值, 同时出现其周围住宅用地的聚集, 特区外该类现象尤为明显; 土地利用组合特征表明各类建设用地均呈很强的空间自相关性, 其中以各类建设用地与工业用 地的组合尤为普遍, 体现了研究区尤其是特区外主要工业承载区中经济活动空间以工业区为 中心的集群效应。

| Abstract: | Land use and land cover change research needs to paid more attention to identify spatial characteristics. Spatial concentration characteristics of urban land use along highways, as an important economic corridor in rapidly urbanized region, are helpful to identify spatial pattern of economic activities and expanding rules of urban land use in the future. This paper analyzed the spatial concentration characteristics of urban land use pattern along highways in Shenzhen in 2005 by means of landscape pattern metrics and association rule of spatial data mining. The paper measured spatial statistical characters and neighborhood characteristics of urban land use pattern along main highways in three dimensions respectively, including single land use type, co-location land use types, and combined land use types. The results are as follows: Industrial area was the primary land use type along highways in Shenzhen. Export-oriented township enterprises accelerated the urbanization process of rural areas outside the special zone. The area of urban public facilities for education and medical treatment was comparatively small, which disturbed the harmony of urban economic functions generally. The landscape metrics of single land use type in all buffer belts presented particular distance-based character, and they also showed a gradually reducing trend. There were some semi-concentration centers, especially in the region 500-1000 meters away from highways, and this could be taken as an important spatial threshold for further research. Co-location distribution pattern showed that two different urban land use types are much closer in adjacent buffer belts near highways. Industrial areas are extremely concentrated in adjacent and much more long-distance buffer belts away from highways, and followed by the concentration of residential districts in the neighborhood. That phenomenon was extremely obvious outside the special zone in Shenzhen. Concerning spatial characteristics of combined land use types, this study indicated strong spatial autocorrelation of each urban land use type in the study area. The combinations of industrial area with other land use types were comparatively common, which reflected the spatial pattern of economic activities of main industrial areas in Shenzhen, especially outside the special zone, and presented the effects of local industrial cluster. |
