摘要
在利用景观扩张指数识别山东省2009—2019年间城镇建设用地扩张模式的基础上,从人、地、业三方面选取指标对山东省城镇建设用地扩张质量及其空间格局进行研究。结果表明:山东省新增城镇建设用地仍处于边缘式扩张主导的阶段,城镇形态较为分散。从全省来看,填充式扩张图斑上各项指标均高于边缘式和飞地式。从市级尺度来看,人口密度、产业活动以及人类活动在不同模式的扩张图斑上表现出不同的特征。各县(市、区)城镇建设用地扩张质量普遍不高,中心—外围差异较为突出,高值区主要分布于中心城区,低值区集中分布于几个重要的生态功能区。城镇建设用地扩张质量空间集聚特征明显,存在若干个连片热点区与冷点区。
The study uses the landscape expansion index to identify the expansion pattern of urban construction land in Shandong Province from 2009 to 2019,and selects indicators from the three aspects of"people-land-industry"to analyze the quality and spatial pattern of urban construction land expansion.Results show that the newly-added urban construction land is still in the leading stage of edge expansion,and the urban form is relatively diffusional.From the perspective of the province,the indicators on the infilling patches are higher than those on the outlying and edge expansion patches;from the city-level,the characteristics of population density,industrial activities,and human activities in three expansion patterns are different.The quality of urban construction land expansion in counties is generally not high,and the"center-peripheral"difference is more prominent.High-value areas are mainly distributed in central urban areas,and low-value areas are concentrated in several important ecological function areas.The quality of urban construction land expansion has obvious spatial agglomeration characteristics,and there are several contiguous hot spots and cold spots.
