摘    要:将GIS和统计分析相结合,以2010年土地利用类型图为基础,选取了斑块面积等8种景观指标,通过计算景观指标分析了拉市海流域景观多样性的空间分布特征.结果表明:林地作为流域内景观基质,由于人为影响其斑块形状较复杂;耕地分布均匀,聚合度连接度都较高;水域分布空间差异性明显,且多以大斑块团聚分布;草地和建筑用地分布零碎但连接度良好;未利用地集中分布于个别村.研究区内景观类型多样性随海拔升高因人类活动影响减弱而降低.

关 键 词:拉市海  景观多样性  景观指标

Abstract:Based on the land use map of 2010,by using the methods of GIS and statistical analysis,it selected 8 landscape metrics to analyze the spatial distribution of landscape diversity in Lashihai watershed.The results showed that: forest land was the landscape matrix for the basin,because of the human activities influencing its patch shape which became more complex;farmland was distributed evenly which had a high degree of aggregation index and COHESION;significant differences presented in spatial distribution of water,and mainly composed with large patches;the patches of grassland and building land was fragmented but connected well;undeveloped land concentrated in several individual village.Within the study area,the diversity of landscape types decreased with increasing elevation due to human dimension reduced.
Keywords:Lashihai  landscape diversity  landscape metrics
