| 摘 要： | 以辽宁盘锦地区为研究对象，基于统一的景观分类系统和景观生态学统计方法，利用遥感和GIS技术，分析了2000-2010年10 a间景观多样性的特征与变化。结果表明，随着经济的发展、城镇化水平的提高，研究区2005-2010年较2000-2005年人类活动为主要驱动力的作用更加明显，斑块总数增加，城镇景观扩张，尤其在双台子区、兴隆台区和辽东湾新区扩张明显，景观格局越加破碎，类型多样性增加，且2005-2010年景观多样性的变化幅度大于2000-2005年的变化幅度。通过叠加分析发现，盘锦地区景观多样性受人类影响的阶段性变化特征突出，建议及早划定盘锦地区生态保护红线，并实行严格的管理制度，保护以湿地景观为基质的景观格局。

| Abstract: | Taking Jinpan of Liaoning, China as research object, and based on the unified landscape, statistical methods of landscape ecology, the characteristics and changes of the landscape diversity in this area during 2000 to 2010 were investigated by using remote sensing and GIS technology. It was found that with the development of economy and urbanization, the landscape changes of the study area were interfered by the human activity were more significant in 2005 to 2010 than 2000 to 2005. The total number of patches firstly decreased and then increased. Urban landscape expanded persistently, especially in Shuangtaizi District, Xinglongtai District and Liaodongwan New District. Landscape patterns of these areas were more fragmented and the type diversity increased. Further more, changes of the type diversity in 2005 to 2010 were greater than 2000 to 2005. Through the overlay analysis, landscape diversity in Panjin was significantly influenced by human activities in periodic variation. It was suggested that to set up red lines for ecological protection in this area, and to carry out strict management regularities to ensure wetland landscape as the matrix of the landscape pattern. |
