摘要
通过斑块密度、斑块平均面积、斑块平均形状破碎化指数和面积加权平均形状破碎化指数4项景观格局指数,结合形态学空间格局分析法(MSPA),从景观和像元层面探索了1995~2015年鄱阳湖生态经济区湿地景观格局演变过程。结果表明:①鄱阳湖生态经济区湿地面积呈现波浪状增长,其内部湿地类型变化较剧烈;②4项景观格局指数均表明研究区湿地呈越加破碎的变化趋势:③MSPA的分析结果与景观格局指数相一致,研究区湿地以“核心区”形态为主。研究结果可为鄱阳湖生态经济区的景观破碎化研究提供参考,并为区域景观格局优化、土地合理管理提供借鉴。
In this paper,landscape indices of Patch Density(PD),Mean Patch Area(MPS),Mean Shape Fragmentation Index(FS1),Area-weighted Mean Shape Fragmentation Index(FS2)and Morphological Spatial Pattern Analysis(MSPA)are used to analyze the evolution process of Poyang Lake Ecological Economic Zone during in the periods of 1995 to 2015 from the landscape and pixel levels.The results show that:①Its wetland area showed a wavy growth,and the internal wetland type changed sharply.②All the four landscape pattern indices indicated that the wetland was more broken than before.③The analysis results of MSPA was consistent with landscape indexes,and the wetland was mainly the“core area”pattern.The results can provide a reference for the study of landscape fragmentation in Poyang Lake Ecological Economic Zone,and for the optimization of regional landscape pattern and rational land management.
