摘要:
 以苏州吴江区为对象，选取1990、2000、2010、2020年土地利用数据，利用Fragstats4.2对1990-2020年水域景观破碎化演化特征进行定量分析，并借助地理探测器模型探讨水域景观破碎化时空特征的驱动因子。结果表明：1）从景观水平破碎化特征分析来看，研究期内吴江区水域景观破碎化程度先增大后减缓：1990-2000年水域景观受到人工建设干扰，空间分布离散；2000-2020年水域景观破碎化程度降低、整体空间格局趋向整合。从类型水平破碎化特征分析，河流、湖泊及内陆滩涂在1990-2000年破碎化程度日益加剧，斑块空间分布离散，2000-2020年水域斑块连接性逐渐增强；水库坑塘斑块类型分布在1990-2010年破碎程度降低，2010年后破碎化程度上升。2）吴江区水域景观破碎化受到自然、社会等多元因素影响，各因子对水域景观破碎化时空分异的影响明显不同，且各驱动因子间存在显著交互增强效应，其中人类活动强度因子影响最为显著。研究结果可为探明水域景观破碎化形成机理提供思路，对苏南水网地区生态环境保护和可持续发展具有参考意义。
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 investigated 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 fragmentation 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 disturbed 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 inland beaches became increasingly intensified during 1990-2000,the spatial distribution of patches was discrete,and the connectivity of water patches gradually increased during 2000-2020.The fragmentation degree 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 provide ideas for exploring the formation mechanism of water landscape fragmentation,and have reference significance for ecological environment protection and sustainable development in the southern Jiangsu water network area.
