| 摘 要： | 在尖峰岭热带山地雨林，对食叶昆虫食叶量测试，供试验种计有２７科５０种。所得结果表明：昆虫食叶面积或重量百分率，各树种变动幅度在０．４５％－２８．０１％之间，平均为７．７１％，这种食叶量水平，对林木生长并无影响。但食叶昆虫的存在，对热带森生态系统来说，在维持生物群落动态平均方面，起着积极作用。

| Abstract: | Fifty tree species belonging to twenty seven families were used to test the leaf-quantity eaten by leaf-eating insects in the tropical mountain rain forest, Jianfengling, Hainan.The result showed that the range of eating percentage either in leaf-area or weight was 0.45%~28.01% among various tree species, averaging 7.71% which had no significant influence on the tree growth.Nevertheless the existence of leaf-eating insects plays a positive role to the tropical forest ecosystem in keeping dynamic balance of the biological communities. |
