摘　　要：笔者选取了淮安市楚州区、洪泽县进行土地利用的景观格局研究,采用了景观格局指数法分析了2区域2000年相关景观格局指数。研究表明:①2区域土地利用结构区别较大,其中洪泽县受人类干扰较少的景观类型占52.52%,而楚州区仅为14.24%,这也受客观因素制约。②2区域土地利用类型按平均斑块面积由大到小排序,楚州区为耕地>建设用地>水域>未利用地>林地;洪泽县为水域>耕地>建设用地>未利用地>林地。③2区域景观要素类型的结构特征表明楚州区较洪译县耕地破碎度、空间导质性更大;2区域斑块数量均较多,但洪译县斑块密度更小,且其建设用地景观形状更趋于规则;两区域的水域景观差别显著;两区域林地、未利用土地景观面积所占比例相差不大,其景观形状指数差别也不大。④2区域总体景观特征表明,洪泽县景观多样性指数,丰富度指数相对较高,优势度指数、破碎化指数相对较低。该研究总体反映了在研究区域的人类活动处于过度状态。Chuzhou District,Hongze County in Huai＇an City were selected to study land use landscape pattern,the landscape pattern index method was adopted to analyze the relative index in those two regions in 2000.The results showed that： the land use structure has significant differences,the landscape type with less human disturbance in Hongze County accounting to 52.52%,while Chuzhou District accounting to 14.24,limited by objective factors.The order of land use type according to average patch area size is as follows.In Chuzhou District,farmlandconstruction landwater areaunutilized landwoodland;in Hongze County,water areafarmlandconstruction landunutilized landwoodland.The structure characteristics of landscape elements indicated that the farmland fragile degree of Chuzhou District is more serious than Hongze County,the patch quantity both are abundant,the patch density of Hongze County is relatively low;water area landscape of two region has significant difference,and the proportion of woodland,unutilized landscape area of two regions is similar,as well as the landscape shape index.The general landscape features indicated that,the landscape diversity index and richness index in Hongze County are relative high,dominance degree index,fragile index are relative low.The research generally reflect the human activities in study area are exorbitance.
