摘要: 针对近年来采茶Camellia sinensis和森林生态旅游等人类经营活动和野生动物（野猪Sus scrofa等）的强烈干扰给肖坑小流域带来了一定程度的生态影响，在景观类型划分的基础上，对景观要素的斑块特征进行了初步研究，以期为生态保护及合理经营提供科学依据。结果表明：常绿落叶阔叶林占该流域总面积的66.49%，周长占总周长的50.67%，是该流域森林景观的主导景观类型；毛竹Phyllostachys pubescens纯林、杉木Cunninghamia lanceolata纯林和茶园占总面积的25.73%，周长占总周长37.85%，是该流域的3类主要景观类型。森林景观要素以小斑块为主，斑块粒级结构比较细密，属细粒状结构。景观要素的面积、周长和斑块数分布等均极不平衡；各景观要素面积分布与周长分布极为相似；景观要素的斑块数分布却没有明显的规律性，其排序与面积、周长分布差异较大；景观要素的斑块形状较简单。景观要素的斑块特征表明，在目前干扰强度下，阔叶林景观的连通性尚好，破碎化程度低；毛竹纯林、杉木纯林和茶园等人工或半人工经营景观的破碎化程度高，建议应该减少强烈的人类经营活动和旅游，特别要加强对阔叶林基质的保护，实现区域可持续发展。表6参20

Abstract: In order to provide a theoretical basis for conservation and management of the forest landscape in Xiaokeng Small Watershed in Laoshan Nature Reserve，Anhui Province，the patch characteristics of forest landscape element were analyzed. The results showed that a mixed evergreen and deciduous broadleaf forest with an area of 66.5% and perimeter of 50.7% of the total research area was dominant. Phyllostachys pubescens forest，Cunninghamia lanceolata forest and Camellia sinensis plantation comprised 25.7% of the total area and 37.9% of the perimeter. In Xiaokeng，many small patches with a relatively fine grain structure dominated the forest landscape element. The area，perimeter，and number of patches of different forest landscape element were very uneven；the distribution trend of perimeter of different forest landscape element is similar to that of area，while the distribution of the number of patches has no obvious regularity，and the order of the numbers of patches，area，perimeter is very different； the patch shape of forest landscape elements is relatively simple. Patch characteristics indicated that the degree of fragmentation for the natural broadleaf forest was lower than for artificial landscapes of Phyllostachys pubescens，Cunninghamia lanceolata，and Camellia sinensis. Therefore，to maintain sustainable development in the region，and especially to enhance protection for the broadleaf forest matrix，intense human activity and tourism should be reduced. ［Ch，6 tab. 20 ref.］
