This paper deals with the phytosociological characters of the Wumon-fir

本文述及云南乌蒙山脉残留分布的急尖长苞冷杉林(即乌蒙冷杉林)的植物群落学特征。此类森林目前只有小面积分布于乌蒙山的海拔3100-3900米处。它是滇中高原北部山地唯一的亚高山针叶林,也是该地植被垂直带谱中的一个重要组成。群落由急尖长苞冷杉组成的单优势林,偶见云南铁杉混生。下木有花楸、榛、荚蒾、柳、树五加、绣球、冬青、杜鹃等属的种类组成。灌木层以箭竹为主,而草本层种类较多。大部分种类为中国-喜马拉雅区系成分。急尖长苞冷杉林的植物群落学特征与滇西北-带的亚高山针叶林非常近似,但乔木层缺乏云杉属和落叶松属的种类。可以认为,此类冷杉林是滇西北、川西南和藏东南这一个亚高山针叶林植被分布区的一个最为东南的边缘类型,它的分布已到了分布区的极限。它是自然历史的残留林,又在人为影响下,面积越来越小。对于此类残留森林,必须严加保护,使其得以发展以扩大自然分布区。如果这样,这对于改变乌蒙山脉的农、林、牧诸方面的面貌,将起着十分积极的作用。

The present paper deals with the secondary forest vegetation after 20years period of natural regeneration. The field study was carried out on Mt.Wuchao near Hangzhou, Zhejiang Province. According to Jaccard’s community index of similarity, the secondaryvegetation was divided into three types:the deciduous mixed forest, theevergreen mixed forest-a sere towards a higher stage of evergreen broad-leafclimax community, and intermediate type. The life forms were according toRaunkiaer’s classification:phaenerophyta (74.4%), chamaephyta (13.5%),hemicryptophyta (4.1%), geophyta (6.8%), and therophyta (1.4%). The highpercentage of phaenerophyta is similar to the life form spectrum of theevergreen broad-leaf forest of Zhejiang Province. The leaf size of thevegetation was mainly microphylla (60.3%) but which is higher than those ofthe evergreen broad-leaf forest in other place of the province. 82.5% of theleaf pattern was simple leaf. The recovery vegetation stratification weredivided into:arborous layer, shrub layer, herbaceous layer and ground layer. According to Lutz’s phytograph index the most important tree specieswere:Lithocarpus glaber, Cyclobalanopsis glauca, and Quercus glandulifera var.brevipetiolata in which density, frequency, cross-sectional area and itsappearence in the under and over story were predominant. Next is Castanopsisfargesii, Castanopsis sclerophylla and Schima superba. The recovery forest has a growing-stock of 50m~3 per hectare, the highestis found to be above 140m~3 per hectare. A total of 62 species of spermatophyta in 27 families and 45 genera wasobserved in the field during the study period and a comparison of its floraand geographical distribution was carried out.

本文是对午潮山森林植被遭破坏后,经过20年的封山育林,植被在恢复过程中的群落学研究。按Jaccard植物群落相似性系数统计,植被可分三个类型:以落叶树种在数量上占优势的混交林;以常绿植物的种类在数量上占优势的混交林;处于二者之间或处于恢复演替过程中的更高阶段。按Raunkiaer生活型谱统计:高位芽植物占74.4%,地上芽植物占13.5%,地面芽植物占4.1%,地下芽植物占6.8%,一年生植物占1.4%,与本省常绿阔叶林的生活型谱有些相似,都是以高位芽植物占优势。叶的性质以小型叶为主,占60.3%,只是微型叶的比例较本省其它各地高。叶型以单叶比例最大,占82.5%,群落在结构上可分乔木层,灌木层,草本层和地被层,亦有数量不多的层间植物,乔木层一般还没有出现层的分化。按Lutz林木结构图解统计表明:石栎、青冈、枹树它们在密度、频度、断面积和上下层中的出现率方面都占优势,是群落中的优势种,其次是丝栗栲、苦槠、木荷。恢复的幼林每公顷蓄积量都在50立方米以上,最高的可达140多立方米。出现的种子植物计有62种,隶属27科45属,文中对这些植物的区系地理成分进行了分析比较。

By using direct harvest method to estimate the seasonal dynamic of shrub and herbaceous layers in Pine plantation, the biomass of the shrub layer on the southern and northern slope in August was 8.05t/ha and 5.78t/ha, the biomass of the herbaceous layer was 0.74t/ha and 0.77t/ha respectively. The total biomass of the Pine plantation on southern and northern slope was 38.08t/ha and 48,68t/ha respectively.
