| 摘 要： | 光皮桦 (Ｂｅｔｕｌａｌｕｍｉｎｉｆｅｒａ)为桦木科落叶大乔木 ,具有生长快、适应性强、材质好、用途广、落叶量大、繁殖容易等特点 ,是一种极有推广前途的优良速生用材树种。由于材质致密坚韧 ,是室内装璜的优质用材。近几年来对天然林过度采伐 ,使得光皮桦天然林资源锐减 ,而人工造林并未引起重视 ,使光皮桦处于渐危状态。为此 ,通过对福建邵武光皮桦天然林进行群落学分析 ,以期为保护光皮桦天然林和推广光皮桦人工造林提供理论依据。1 研究地点与方法调查地点位于福建省邵武二都村天然阔叶林 (东经 1 1 7°59′,北纬 2 7°44′) ,该片…

| Abstract: | Based on the data collected from sampling plots in \?tula luminifera\% natural forest community located in Shaowu Fujian Province,the important values of main tree species in the comnunity were determined,the community appearance,vertical ctructure,and population dynamics were analysed.The results showed that the community was dominated by Betula luminifera,Catsanopsis lamontii and Liquidambar formosana. The community could be divided into 4 layers.The tree layer could be divided into 3 sulayers in terms of height.The dominance of \?tula luminifera\% in the forest will decrease as the succession proceeds. |
