摘要：全球气候变化背景下,随着城镇化高速发展,城市内涝灾害愈加明显,已成为造成喀斯特地区损失较为严重的灾害之一。选择西南喀斯特山地城市——贵阳市为研究区,基于2016—2020年实测和调查的内涝灾害数据,运用空间自相关和相关分析方法,探究景观格局对城市内涝的影响。结果表明:1)2016—2020年贵阳市主城区内涝频发,且空间分布差异性显著,呈现显著的空间自相关和集聚分布特征。2)不透水面、绿地与内涝频次的相关性显著,分别呈正、负相关。3)内涝周边500 m缓冲区内景观由少数聚集程度大的斑块构成,优势度较高,景观中的优势斑块类型仅有一种或少量几种;不同土地利用类型的景观格局空间聚集情况差异显著,其中铁路与道路、房屋建筑的景观指数空间聚类较为显著。4)内涝与土地利用类型面积的关系不显著,但与土地利用类型的景观指数有显著相关性,且不同土地利用景观格局对内涝的影响差异较大。研究结果为喀斯特城市内涝防治和景观格局规划管理提供重要参考和借鉴意义。
With the influence of global climate change and rapid development of urbanization,urban waterlogging has occurred frequently,and has become one of the disasters that cause serious losses in Karst areas.In this study,Guiyang,a Karst mountainous city in Southwest China,was selected as the study area.Based on the observed and investigated waterlogging disaster data in the study area from 2016 to 2020,spatial autocorrelation analysis and correlation analysis methods were used to explore the impact of urban landscape pattern on urban waterlogging.The results showed that:1)From 2016 to 2020,the waterlogging occurred frequently in the main urban area of Guiyang,and its spatial distribution difference was significant;the waterlogging points showed significant spatial autocorrelation and concentration distribution pattern.2)Impervious surface and vegetation had significant correlation with the frequency of waterlogging,which showed positive and negative correlation respectively.3)The landscape inside the 500 m buffer zone around the waterlogging point was composed of a few patches with a high degree of aggregation,and the dominance value was high.There was only one or a few dominant types;the spatial clustering of landscape patterns of different land use types was significantly different,among which the landscape index of railway,road and housing construction was relatively more significant.4)The relationship between waterlogging and land use area was not significant,but there was a significant correlation between waterlogging and land use landscape index.This study will provide an important reference for the prevention and control of waterlogging and the planning and management of landscape pattern in Karst cities.
