摘要:
 景观格局指数是反映景观结构与空间特征的量化指标，通过景观特征的指数化来描述景观格局现状。选取苏州市吴江区七都镇2000、2010、2020年3期土地利用数据，借助ArcGIS、FRAGSTATS、SPSS等软件，对其景观格局演变特征进行分析比较，并对该地区景观格局演变的驱动因素进行探究。结果表明，1）通过土地利用转移矩阵发现，耕地和林地面积呈减少趋势，分别减少了872.28 km2（-13.85%）和7.92 km2（-15.94%），部分耕地和林地转化为了建设用地，相应的建设用地面积占比由10.35%提升至19.45%，农用地被侵占的现象显著。2）通过景观格局演变分析发现，水域、草地以及林地破碎化程度增强、边界被割裂的程度加剧，景观复杂程度增加；建设用地破碎化程度有所减弱，空间分布上趋向集中，斑块类型复杂程度下降，边界变得更加简单和规则。2000-2020年，七都镇景观多样性增强，景观整体向着均衡化发展。3）通过驱动力分析发现，城镇建设经济发展以及产业结构调整等因素累积贡献率达到96.74％，是导致七都镇景观格局变化的主要因素。
Abstract:
 The landscape pattern index is a quantitative index reflecting the structure and spatial characteristics of the landscape,and describes the current situation of the landscape pattern through the indexation of landscape characteristics.In this study,we selected the land use data of Qidu Township,Wujiang District,Suzhou City,for three periods of 2000,2010 and 2020,and analyzed and compared the landscape pattern evolution characteristics with the help of ArcGIS,FRAGSTATS and SPSS,and explored the driving factors of the landscape pattern evolution in this area.The results showed that 1) through the land use transfer matrix,it was found that the area of cultivated land and forest land decreased by 872.28 km2 (-13.85%) and 7.92 km2 (-15.94%),respectively,and some of the cultivated land and forest land transformed into construction land,and the construction land area increased from 10.35% to 19.45%,and the encroachment of agricultural land was significant.2) The analysis of the evolution of the landscape pattern showed that the fragmentation of water,grassland and woodland increased,the boundary had been fragmented,and the complexity of the landscape increased.The fragmentation of construction land weakened,the spatial distribution tended to be concentrated,the complexity of the patch types decreased,and the boundary became more simple and regular,indicating a trend of balanced development.3) The driving force analysis revealed that the cumulative contribution rate of the factors such as urban construction and economic development as well as industrial structure adjustment reached 96.74%,which were the main factors leading to the change of landscape pattern in Qidu Township.
