【摘要】 水文对森林植物群落的类型、结构、生活型谱、排序和动态做了初步研究。结果表明:森林植物群落分2个植被型,4个群系,19个群丛组;群落垂直结构分乔术、灌木、草本3层,植物组成分属于34科、76属108种;群落生活型谱反映了气候条件;群落排序结果满意;顶极植物群落为松栎林,山杨、白桦林将为辽东栎林演替,油松林与山杨林、白桦林之间的动态演替关系值得进一步研究。更多还原

【Abstract】 The types,structure,biological spectrum,ordination and dynamic of forest communities were studied in the paper.The study shows that the forest communities can be divided into 2 vegetation types,4 formations and 19 association groups,the vertical structure of communities was divided into three layers-arbor,bush and grass,and there are 108 species of 76 genus in 34 families.The analysis of biological spectrum ref lects the loca climate.The polar ordination of forest communities is reasonable.The climax is Qurcus liaotungensis and Pinus tabulaeformis forests. Populus davidiana and Betulla platyphylla will be replaced by Q.liaotungensis. The relationship between P.tabulaeformis forests and P.davidiana and B. platyphlla forests need to be studied extensively.更多还原
