Spatio-Temporal Evolution and Driving Factors of Water Landscape Fragmentation in Southern Jiangsu Water Network——A Case Study of Wujiang District
摘要
Abstract
In this study,the temporal and spatial evolution characteristics of water landscape fragmentation in the southern Jiangsu water network region were quantitatively analyzed,and the driving factors were in-vestigated to provide a basis for the protection of water ecological environment.Taking Wujiang District of Suzhou City as the research object,land use data from 1990,2000,2010 and 2020 were selected,and the characteristics of water landscape fragmentation evolution from 1990 to 2020 were quantitatively analyzed by Fragstats4.2,and the driving factors of the spatial and temporal characteristics of water landscape frag-mentation were discussed by means of the geographic detector model.The results showed that 1)from the analysis of the characteristics of landscape level fragmentation,the degree of water landscape fragmentation in Wujiang District increased first and then slowed down:from 1990 to 2000,the water landscape was dis-turbed by artificial construction,and the spatial distribution was discrete;from 2000 to 2020,the degree of water landscape fragmentation decreased and the overall spatial pattern tended to be integrated.From the analysis of the characteristics of type level fragmentation,the fragmentation degree of rivers,lakes and in-land beaches became increasingly intensified during 1990-2000,the spatial distribution of patches was dis-crete,and the connectivity of water patches gradually increased during 2000-2020.The fragmentation de-gree of reservoir pit patches decreased from 1990 to 2010,and increased after 2010.2)The water landscape fragmentation in Wujiang District was affected by multiple factors,such as natural and social factors,and each factor had significantly different effects on the spatial and temporal differentiation of water landscape fragmentation,and there was a significant interaction enhancement effect among the driving factors,among which the human activity intensity factor had the most significant impact.The results of this study can pro-vide ideas for exploring the formation mechanism of water landscape fragmentation,and have reference sig-nificance for ecological environment protection and sustainable development in the southern Jiangsu water network area.关键词
