摘要
武陵山区地处湖南、湖北、重庆和贵州省交汇处,是光皮树分布的中心区。武陵山区北部光皮树资源分布、生境、产量及其果实含油率调查表明:该区域光皮树主要分布在海拨1050米以下的石灰岩、白云岩,紫色砂岩区,依靠鸟类传播繁衍,影响光皮树自然分布的主要因子是地表光照强度、土壤表层保水能力和肥力;该区域光皮树野生资源丰富,年鲜果总产量330.8 t左右,果实含油率高达35.06%,具有较大的开发利用价值。
Wuling Mountain Region located at the junction of Hunan,Hubei,Chongqing and Guizhou,which is the distribution center of Swida wilsoniana.In this paper,the resource distribution,ecological surrounding,yield and fruit oil rate of S.wilsoniana in northern Wuling Mountain Region were studied.The results showed that the wild S.wilsoniana plants which depended on birds for their reproduction were mainly distributed in the areas with soil types developed from limestone,dolomite and purple sandstone at an altitude below 1 050 m.The illumination intensity on soil surface,topsoil water retention and topsoil fertility were the major factors affecting the distribution of S.wilsoniana.In this region,the wild S.wilsoniana resources were abundant with annual total fresh fruit yield of about 330.8 tons and with fruit oil rate of 35.06%.The resources of S.wilsoniana in northern Wuling Mountain Region have great value for exploitation and utilization.
