They are the dominant organisms in aeratedsoils ( frey et al. 1999 ), typically accounting for 10 % ? 60 % of the biomass inforest litter ( newell 1992 ; metting 1993 )
在含有氧合的土壤中它們也是優勢生物,典型的證明是在森林的枯枝落葉層中有生物量的10 % ~ 60 % 。There is a carpet of leaves and pine needles on the forest floor
森林中的地面上有一層厚厚的落葉和松針。There are obvious differences between the small protected area and the nature reserve and we traditionally preferred to do researches on the climax forest communities of the nature reserve, and do less researches on the forest communities of the nature reserve which is being built up and resumptive. the studies on the ecological characteristics of mid - subtropical evergreen broad - leaved forest of the small protected area were of importance
生態保護小區與自然保護區具有明顯的區別,傳統上偏重於對自然保護區的頂極群落研究,對正處在重建和恢復過程的生態保護小區森林群落研究甚少,所以對生態保護小區中亞熱帶常綠闊葉林群落生態學特徵研究具有重要意義。The vegetation was chiefly dominated by coniferous - brodleaved mixed forests, with many evergreen broadleaved species in their young growth stage, it can be suggested that the vegetations in the meizilake area were in a successional stage from coniferous - broadleaved mixed forests to evergreen broadleaved forests. however, the formation of the climax community evergreen broadleaved forests needs a long time
可以看出,梅子湖森林植被群落正處于由針闊葉混交林常綠闊葉林的演替階段,群落中的思茅松林正在向被常綠闊葉林替代的方向發展,但要演替為頂級群落,還需要很長的時間。The close canopy of fragmental evergreen broadleaved forest community is less than the one of continuous evergreen broadleaved forest, and the plant species of fragmental evergreen broadleaved forest community are also less than those of continuous evergreen broadleaved forest, and there are some conifers in the fragmental evergreen broadleaved forests
群落郁閉度不如連續森林大,植物種類也不如連續森林豐富,而且其中夾雜著一些針葉樹。常綠成分種類組成不如連續森林豐富,針葉成分數量上較連續森林的多。Niche breadth of four dominate populations at three age groups was studied by the methods of resource utilization ability and ratio. the result shows that : symplocos sectchuanensis is a typical gengeration species whi ch resource utilization ability is strong, and distribution is wide. meanwhile, go rdonia acuminata, castanopsis fargesis and pinus massoniana specialized at some d egree in resource utilizationm, their distribution is limited. especially, the ju venile of pinus massoniana specialized outstandingly. with the devlopment of pinu s massoniana, which is the pioneer population in mt. jinyun, the environment become s unfit to it ' s juvenile. it turns to needle and evergreen broad - leaves mixed fo r est. because the tolerance toward shading of gordonia acuminata is lower than tha t of castanopsis fargesis, gordonia acuminata will be substituted by castanopsis fargesis and other evergreen broad - leaves species are the edificators. the popul ation ' s ability of resource utilization is the inner factor of population distri bution and community succession. the distribution of light and the concentrate of nutrient ( such as n ) is the outer factors of community succession
對縉雲山森林植被的4個優勢種群3個年齡級生態位寬度進行了研究.結果表明,川灰木利用資源的能力最強、分佈廣,為典型的泛化種.大頭茶、栲樹、馬尾松對資源的利用在一定程度上特化,分佈上有一定的局限性.馬尾松的中齡組與幼齡組特化現象十分顯著.縉雲山森林植被的先鋒種馬尾松的發展,導致環境的改變不適于其幼齡個體的生長,群落演替到針闊葉混交林階段,最後發展為以栲樹等為建群種的常綠闊葉林.種群的資源利用能力,是種群分佈與群落演替的內在原因,光因子和營養元素(如n )是群落演替的主要外部動力The area of plot sampling in every typical community locality on the small protected area in huangyinling were 1 600m2. the site factors were investigated by the method of forest community investigation, and the species, body number, height, d. b. h., coverage of herbage and so on were recorded
