以浑河上游水源涵养林为研究对象,通过对4种典型林分类型的树种组成、枯落物持水特性和土壤持水特性进行的研究,结果表明:各类型林分的树种组成复杂程度顺序为核桃楸+花曲柳+五角枫混交林>冷杉+白桦+五角枫针阔混交林>辽东栎+五角枫天然林>人工日本落叶松纯林,阔叶混交林和针阔混交林树种结构稳定性更强;不同林分类型枯落物和土壤最大持水量的大小顺序为核桃楸+花曲柳+五角枫混交林(4003.38 t hm-2)>冷杉+白桦+五角枫针阔混交林(3838.54 t hm-2)>辽东栎+五角枫天然林(3444.15 t hm-2)>人工日本落叶松纯林(3208.85 t hm-2)。
以渾河上遊水源涵養林為研究對象,通過對4種典型林分類型的樹種組成、枯落物持水特性和土壤持水特性進行的研究,結果錶明:各類型林分的樹種組成複雜程度順序為覈桃楸+花麯柳+五角楓混交林>冷杉+白樺+五角楓針闊混交林>遼東櫟+五角楓天然林>人工日本落葉鬆純林,闊葉混交林和針闊混交林樹種結構穩定性更彊;不同林分類型枯落物和土壤最大持水量的大小順序為覈桃楸+花麯柳+五角楓混交林(4003.38 t hm-2)>冷杉+白樺+五角楓針闊混交林(3838.54 t hm-2)>遼東櫟+五角楓天然林(3444.15 t hm-2)>人工日本落葉鬆純林(3208.85 t hm-2)。

Taking water conservation forest in upstream Hun River as the research object,tree species composition, water-holding characteristics of litter and water retention characteristics of soil of four typical types for stand were studied.Result shows that:the complexity of the species composition,mixed forest of J uglans mandshurica +Fraxinus rhynchophylla + Acer mono > coniferous and broadleaved mixed forest of Abies fabric + Betula platyphylla +Acer mono >natural forest of Quercus wutaishansea +Acer mono > artificial pure forest of Larix kaempferi .Stability of tree structure of broadleaved mixed forest and coniferous and broad-leaved mixed forest are greater.The descending order of litter and soil water holding capacity is the different types of stand mixed forest of J uglans mandshurica +Fraxinus rhynchophylla +Acer mono (4 003.38 t hm-2 )> mixed forest of Abies fabric +Betula platyphylla +Acer mono (3 838.54 t hm-2 )> natural forest of Quercus wutaishansea + Acer mono (3 444.1 5 t hm-2 )>artificial pure forest of Larix kaempferi (3 208.85 t hm-2 ).
