Abstract
After experiencing the period of rapid urbanization,non-construction land in urban and rural areas,as the landscape foundation and spatial structure foundation of urban development,is facing problems such as scale reduction and ecological degradation,seriously affecting regional ecological security and urban sustainable development.This study takes Suzhou City as an example,based on six periods of land use data from 1995 to 2020,using Fragstats 4.0 software and GTWR analysis,to explore the characteristics of landscape pattern evolution of non-construction land in urban and rural areas,and reveal its main influencing factors.The results show that:(1)non construction land in urban and rural areas presents three stages of slow reduction,rapid reconstruction,and integrated stability;(2)The overall landscape pattern of non-construction land in urban and rural areas tends to be miniaturized,fragmented,regularized,continuous,and diversified;(3)NDVI and urban land proportion factors are the dominant factors in the evolution of landscape patterns,and their changing characteristics are consistent with the spatiotemporal changes in landscape patterns.关键词
