摘要
以纵向岭谷区云南核心区为研究区,利用空间分析方法,研究了区域道路网络的空间分布差异;进一步统计道路影响下各县市的土地利用面积,分析了道路网络影响下区域土地利用的分维数和稳定性指数的变化;利用回归分析,研究区域道路网络与土地利用的空间联系。结果表明:纵向岭谷区道路网络与其影响下的土地利用均表现出相似值之间的空间集聚效应。回归分析发现道路网络在空间上的扩展,不仅与区域土地利用相关,而且还与其空间滞后因子有关。
Road network and its extension have important impacts on ecosystem.Exploring relation between road network and ecosystem can provide some reference value for road and surrounding ecosystem management.Based on the road network of LRGR,spatial discrepancy of regional road network distribution was investigated using Exploratory Spatial Data Analysis.Then we counted land use area affected by road network in each counties and studied the variability for fractal dimension and stability indexes of land use.Through spatial regression analysis,we studied relation between road network and land use.The results showed that the distribution of road network and land use affected in LRGR was spatial clustering of similar value.Regression analysis indicated that spatial expansion of road network was not only correlation with regional land use,but also with spatial lag factors.
