不同演替阶段森林群落优势种苗木叶形态解剖结构比较研究

The Comparative Study on Leaf Anatomic Characteristics of Dominant Species Seedlings in Different Stages of Forest Secondary Succession

对广东南亚热带森林次生演替序列的不同阶段群落优势种的苗木叶子形态等特征开展了比较研究．结果表明：根据叶子等形态特征，认为马尾松苗木最适合生长在全日照（供水正常）的环境和林缘（荫蔽度0．2左右）的环境中；荷木、藜蒴、茸荚红豆和黄果厚壳桂，适合生长在每日照光1h和林富以及荫蔽度0．2左右的林缘环境中．

This paper deals with the comparative study on leaf anatomic characteristics of dominant species seedlings in different stages of forest secondary succession, Guangdong province. The following results were summed -up: Pinus massoniana seedings grow better in the habitats of photic rate=80%~100% than in other habitats; the seedlings of Schima superba, Castanopsis fissa, Ormosia pachycarpa,and Cryptocarya concinna grow better in the forest gap and forest edge habitats, than in other habitats, based on the comparative study on their leaf anatomic characteristics.
