摘要:
本文以龙泉驿区为例,采用ArcGIS平台下的核密度估算并结合景观格局分析方法,定量分析了路网扩展与周边景观格局的时空演变特征,结果表明:(1)路网高密度区主要分布在龙泉驿的西部低平城区,中密度广布于市郊周边,呈现出个数多、分布连续的特点,低密度区路网则分散在东部以及较偏远山区;(2)景观格局上,建设用地、耕地在高密度区受道路影响最为明显,其影响程度随着路网密度的降低逐渐减弱,而园地和林地所占比例开始增加;(3)2005-2015年各景观类型指数变化幅度差异明显,其中建设用地、耕地、水域、其他用地景观类型不同程度破碎化,只有园地、林地呈集聚趋势.
Abstract:
This article takes longquanyi district as an example and use the ArcGIS platform KDE estimation and landscape pattern analysis method to quantitatively analyze the road network expansion and evolution of the surrounding landscape pattern. The result shows:(1)The road network density area are mainly distributed in the low area of west Longquanyi, the medium density area is in the suburbs surrounding which presents characteristics of numerous and continuous; the low density area road network is dispersed in the east and the remote mountain area;(2)On the landscape pattern, construction land, cultivated land are affected by roads most evidently in the area of high density, but the degree decreases gradually with the reducing of road network density, and the proportion of garden and forest land began to increase;(3)From 2005 to 2015, there were evident differences in variation index of various types of landscape. Among them, the construction land, arable land, water, land for other landscape types presented a status of fragmentation in different degrees, only garden land and forest land showed a trend of agglomeration.
