| 摘 要： | 基于多时段遥感数据资料,应用景观生态学理论和方法、采用景观格局指标和斑块面积谱定量分析法,研究了1985—2006年成都市林地景观格局的动态变化。结果表明:研究时段内,成都市由于快速城市化过程导致林地斑块受到分割和转化,林地景观格局特征变化复杂,主要表现为林地面积持续减少,斑块形状趋于规则,斑块边缘密度和碎裂化指数增加。从林地斑块的粒级结构特征看,中、小斑块的数量最多,大型斑块的面积占绝对优势,且中、小斑块的数量和面积都表现为先减少后增加,体现出林地剧烈的转化和破碎化过程。

| Abstract: | Based on the remote sensing data,the dynamic changes of forest landscape patterns during 1985 and 2006 were analyzed using landscape pattern indices and landscape patch area of landscape ecology. Results indicated that during the study period,the fast urbanization process had made strong segmentation and transforming impacts on forest land. The changes of forest landscape pattern were complicated in Chengdu,which embodied the area of forest land was gradually decreasing,the patch shape tended to be simplifi... |
