南亚热带季风常绿阔叶林是华南地区典型代表植被类型.由于人为干扰,其现存面积日益减少.为加强保护,对这一植被类型中的演替顶级种厚壳桂(Cryptocarya chinensis)种群在人为干扰下的数量和分布格局进行了研究.研究地点设在广东省广州市萝岗长龙村村边.此林为南亚热带次生季风常绿阔叶林,受当地农民的干扰很大.样方面积是50×100 m2.研究结果表明,和较少受人为干扰的种群相比,这一种群趋于随机分布,特别是小树和幼苗阶段的个体.种群数量的调查研究表明这一种群幼苗库明显不足,表明人为干扰对这一种群的更新影响较大.认为在加强保护区等建设的同时,对分散在各地点的典型植被类型要进行保护,特别是加强对周围居民的保护意识教育.
南亞熱帶季風常綠闊葉林是華南地區典型代錶植被類型.由于人為榦擾,其現存麵積日益減少.為加彊保護,對這一植被類型中的縯替頂級種厚殼桂(Cryptocarya chinensis)種群在人為榦擾下的數量和分佈格跼進行瞭研究.研究地點設在廣東省廣州市蘿崗長龍村村邊.此林為南亞熱帶次生季風常綠闊葉林,受噹地農民的榦擾很大.樣方麵積是50×100 m2.研究結果錶明,和較少受人為榦擾的種群相比,這一種群趨于隨機分佈,特彆是小樹和幼苗階段的箇體.種群數量的調查研究錶明這一種群幼苗庫明顯不足,錶明人為榦擾對這一種群的更新影響較大.認為在加彊保護區等建設的同時,對分散在各地點的典型植被類型要進行保護,特彆是加彊對週圍居民的保護意識教育.

Lower subtropical monsoon evergreen broad-leaved forests are of high conservation significance in South China.Because of human activities, the forest has been largely destroyed; the remaining fragments are now mainly in several protected reserves. To further protect this forest outside the reserves and to study human influences on it, we analyzed the spatial pattern of Cryptocarya chinensis, a dominant tree in the forest near Changlong village, Guangzhou, China. Compared with low human disturbance forests, in which C. chinensis was clumped, we found that trees were randomly distributed, especially the young life stages. Human activities in this forest have also led to the decline of the C. chinensis seedling bank, suggesting that the population is regenerating badly.
