摘要
本文系“贵州省古森林残存群落”系列调查之二．着重对务川县鹿坪村白果园及务川县丰乐镇大院子川王庙两处古森林残存群落中的银杏种群进行了定量研究，相应介绍了森林群落的结构、成分、数量及立木的物侯型级．根据现有资料证明：两处森林仍具有常绿阔叶林的典型的群落特征．白果园森林群落应属“针阔叶混交的古森林残存群落”；川王庙森林群落则属于“常绿与落叶阔叶混交的古森林残存群落”．在上述群落中，银杏种群同森林中其它种群一道沿着天然森林群落的自然规律进行生长、发育和更新，具有同其它野生植物种群一致的生长发育特性，应是古森林残存群落中处于自然状态万的野生性银杏种群．
This is the second parts of the survey data on ailcient ginkgo biloba deleted communities in Guizhou Province. In this paper, quantitative research of ginkgo biloba comnunity in ancient deleted communities were conducted mainly in two sites in Wuchuan County : Baiguoyuanof Luping village and Chuanwang Temple of Fengle Town. The smicture, ingredient, quantity and stumpage phenological types of the above two tbrest communities were also recominended accordillgly. The data indicated that the two forest conununities have typical charactcristics of laurilignosa . Baiguoyuan forest community is deleted community of mixed aciculignosa and broad-leaved forest, forest community of Chuanwang Temple is belonged to the deleted community of mixed laurilignosa and aestilignosa. In the above two forest communies , ginkgo biloba populations, following with the growing, developing and rellewing rules of natural forest communities, have indentical growng and developillg characteristics of wild populations.
