不同人为干扰尺度对米槠群落外貌特征影响研究

从群落外貌探讨不同人为干扰尺度对福建武平米槠林的影响。结果表明:随着人为干扰尺度(CK对照、A级择伐更新、B级天然更新、C级人工促进天然更新和D级杉木林)的加大藤本植物、地面芽植物、地上芽植物、中型叶、草质叶、复叶和落叶的种类逐渐上升或呈“S”型上升,而高芽位植物、小型叶、革质叶、全缘叶、单叶和常绿的种类逐渐下降或呈“S”下降;CK、A级、B级和C级的外貌是由革质、单叶、小型叶为主的常绿高位芽植物所决定的,而D级由草质、单叶、中型叶为主的常绿高位芽植物所决定的。

The Different Effects of Scale of Human Disturbance on the Castanopsis Carlesii Community Appearance

The different effects on community appearance of Castanopsis carlesii forest in Wuping under the different scales of human disturbance are discussed.The results show that with the enhancement of the disturbance scale the species of vines,chamaephphytes,hemicryptophytes,Mesophyll, herbaceous,compound leaves and deciduous leaves is increased or it's rise curves pattern "S";and the species of phanerophytes,Microphylly,coriaceous leaves,entire leaves,single leaves,evergreen is decreased or it's deline curves pattern "S";the evergreen phanerophytes of microphylly,coriaceous leaves and single leaves are determined by the community appearance of CK,class A,class B and class C,but the evergreen phanerophytes of herbaceous,single leaves and Mesophyll are determined by the community appearance of class D.
