摘要: 利用遥感、GIS手段对辽河三角洲的湿地景观进行研究,并选用6种不同的方法对研究区的景观破碎化程度进行分析.结果表明,研究区的景观破碎化程度较低,总体斑块密度为0.286个·km-2,廊道密度为1.098km·km-2,聚集度指数为0.955.景观破碎化与人类活动密切相关,随着人类活动的增加,景观破碎化程度加深.廊道景观的发展是景观破碎化的前提与动因.

Abstract: In this paper,the wetland landscape of Liaohe delta is studied with remote sensing and GIS and six approaches are used to analyze its fragmentation.The results show that this area is lightly fragmented,the patch density of landcapes is 0.286 individual·km-2,the corridor density is 1.098 km·km-2 and the aggregation index of various landscapes is 0.955.Landscape fragmentation is closely related to human activites,and the fragmentation level is increased with increasing human activities on the landscapes.The expansion of corridors is the premise and impetus of landscape fragmentation.
