摘要:
 为了研究长沙市森林景观的结构特征，以2011年长沙市TM卫星遥感数据、地形图和实际调查数据为数据源，从斑块水平和景观水平选择17个格局指数，运用Fragstats进行景观指数计算。结果表明：1）从斑块水平分析长沙市城市景观结构：林地景观面积占研究区总面积的65.17%，最大斑块指数、斑块形状指数和平均斑块面积均显著高于其他类型景观，表明林地景观在研究区域内占绝对优势；耕地的斑块数量最多，存在较高的连通性，且空间形状复杂；草地与未利用地的斑块数量、斑块面积都比较小。2）从斑块水平分析长沙市森林景观结构：长沙市城市森林各类型景观斑块面积最大为附属城市森林，达到3 644.87 hm2，其斑块数量明显也多于其他类型的城市森林，呈现极显著的优势。其余几种景观斑块面积大小依次为：附属城市森林＞公共城市森林＞生产城市森林＞防护城市森林＞道路城市森林。3）从景观水平分析，长沙市森林景观的形状指数为114.85，高于长沙市城市景观的形状指数101.28，表明构成长沙市总体景观的斑块形状更加复杂；长沙市城市景观Shannon多样性指数为1.23，低于长沙市城市景观Shannon多样性指数1.45，因为总体景观的各个组成类型较为齐全。
Abstract:
 In order to understand the forest landscape structure in Changsha,an investigation was conducted by using the TM satellite remote sensing data in 2011,the topographic map and the site survey data.Seventeen pattern indices from the patch level and landscape level were selected,and the Fragstats landscape indices were calculated.The results showed that 1) to analyze the urban landscape of Changsha from the patch level: forest landscape occupied 65.17% of the total area,the index of maximum patch,index of patch shape,and average patch area were all higher than those of other landscape types,showing its absolute priority and complexity of the spatial shape within the study area.For cultivated land,the patch number was the highest,high connectivity existed among the patches,and the space shape was complex.For the grass land and uncultivated land,their patch number and area were small.2) To analyze the urban forest landscape of Changsha from patch level: the attached urban forests presented the largest patch area and patch number,with a total area of total 3 644.87 hm2.The patch areas of different forest types were in the order of attached urban forest>public urban forest>productive urban forest> shelter urban forest>road side urban forest.3) From the vies of landscape,the shape index of the urban forest landscape of the city was 114.85,higher than that of the overall urban landscape of the city (101.28),showing the complexity of the patch shape of the overall landscape of the city.The Shannon diversity index of urban landscape of the city was 1.23,lower than that of the overall urban landscape of the city,due to the completeness of the landscape types of the overall urban landscape of the city.
