摘　　要：为了解江苏省近35 a来的景观格局变化特征,以1980~2015年7期土地利用数据为基础,对江苏省各景观格局指数、景观稳定性及其与人为干扰度的关系进行分析,结果表明:①从类型上看,江苏省建设用地的破碎化程度最高且形状最不规则,但随时间趋于完整、规则;耕地和水域的斑块聚集程度和紧凑度高,但呈逐渐降低的趋势。②从整体上看,江苏省整体的景观类型复杂程度增大,空间连通性逐渐降低,景观多样性和异质性增加;各景观类型面积趋于均匀化,但优势景观类型对整个景观的控制作用仍然较强。③江苏省1980~2015年大部分区域景观稳定性较低,人为干扰度较高,且不同时期之间的变化较小。④人为干扰度与斑块密度、景观分离度、香农多样性指数、香农均匀度指数、景观稳定性在15 km×15 km尺度相关性最高,与总边缘对比度指数、蔓延度指数在2 km×2 km尺度达到最高的相关性。该研究成果为解决建设用地的供需问题、优化土地利用结构、保护生态环境等提供科学依据。In order to understand the change characteristics of landscape pattern in Jiangsu Province in recent 35 years,based on the seven periods of land use data from 1980 to 2015,this paper analyzes the landscape pattern index,landscape stability and their relationship with human disturbance degree in Jiangsu Province.The results show that:(1)In terms of types,the fragmentation degree of construction land in Jiangsu Province is the highest and the shape is the most irregular,but it tends to be complete and regular with time;The patch aggregation degree and compactness of cultivated land and water area are high,but they show a decreasing trend.(2)On the whole,the overall complexity of landscape types in Jiangsu Province increases,the spatial connectivity decreases gradually,and the landscape diversity and heterogeneity increase;The area of each landscape type tends to be uniform,but the dominant landscape type still plays a strong role in controlling the whole landscape.(3)From 1980 to 2015,the landscape stability of most regions in Jiangsu Province was low,the human disturbance was high,and the change between different periods was small.(4)The correlation between human disturbance and patch density,landscape division index,Shannon’s diversity index,Shannon’s evenness index and landscape stability is the highest on 15 km×15 km scale,and the correlation with total edge contrast index and contagion index is the highest on 2 km×2 km scale.The research results provide a scientific basis for solving the problem of supply and demand of construction land,optimizing land use structure and protecting ecological environment.
