摘　　要：探讨了凉水原始红松阔叶林自然保护区区系特点.凉水原始红松阔叶林属于长白植物区系,植物种类丰富,共有种子植物80科243属444种.最大的科是菊科,共有植物48种;植物种类超过20种的科有杨柳科、毛茛科、蔷薇科、禾本科、莎草科等.属于这些科的植物共有152种,占凉水种子植物种类总数的34.23%.裸子植物1科4属6种;被子植物79科239属438种,其中双子叶植物63科188属352种,单子叶植物16科51属86种.植物分布区类型分析表明凉水原始红松阔叶林内种子植物可分为4大类性质的区系成分,共有16个分布型16个变型,种类成分较复杂,区系性质为温带性质,特有种所占比例较高,区系古老,区系来源为温带区系成分.The paper dealed with the flora characteristics of primary broad-leaved and Korean pine forest in Liangshui Natural Reserve. The results showed that the primary broad-leaved and Korean pine forest belonged to the flora of Changbai, and the kinds of plants were abundant. There were 444 species in 243 genera and 80 families of spermatophyte. Among those the main family was compositae,and there were 48 families of plants. The families more than 20 were Salicaccac, Ranunculaceae, Rosaceae, Poaceae, Cyperaceae and etc. There were 152 species in these families, and they accounted for 34.23% of the total number of spermatophyte in Liangshui Natural Reserve. There were 6 species in 4 genera and 1 family of gymnosperm, and 438 species in 239 genera and 79 families of angiosperm; among these including 352 species in 188 genera and 63 families of dicotyledons and 86 species in 51 genera and 16 families of monocotyledons. Analyses on the distribution area types of spermatophyte showed that primary broad-leaved and Korean pine forest in Liangshui Natural Reserve could be divided into 4 main kinds of floristic components; there were 16 distribution types and 16 sub-types; the components of the kinds were more complex;the character of flora had a temperate characteristic;endemic species accounted for higher proportion;the flora was archaic;the origin of flora was temperate floristic component.
