There were only 94 vascular plant species, belonging to 50 family and 75 genera. The dominant species in the communities were deciduous broadleaf species Liquidambar formosana, Robinia pseudoacacia, Ailanthus altissima, Acer buergerianum, and Celtis sinensis, evergreen broadleaf species Cinnamomum camphora and Elaeocarpus glabripetalus, and Phyllostachys heterocycla. Robinia pseudoacacia+Cinnamomum camphora community had the highest Shannon-Wiener index (1757) and Phyllostachys heterocycla+Acer buergerianum community had the highest Simpson index (0163), but no consistency was observed between the curves of H and D. For vertical structure, most communities had no significant understory stratification.

结果表明：辰山植物区系以泛热带和北温带占优势，具有典型亚热带和温带成分交汇和南北植物分布交错特征；但保育区内种类单一，维管束植物仅有49科69属94种；主要群落是以枫香、刺槐、臭椿、三角枫和朴树等为优势树种的落叶阔叶林，以香樟和秃瓣杜英等为优势树种的常绿阔叶林，以及毛竹林；物种多样性普遍较低，Shannon-Wiener多样性指数最高为刺槐+香樟群落（1.757），Simpson均匀度指数最高值为毛竹+三角枫群落（0.163）；多样性指数曲线和均匀度指数曲线不具有一致性的变化趋势；多数群落垂直结构中无明显林下分层现象；演替前期的落叶乔木种群后续个体不足。

Patch characteristics indicated that the degree of fragmentation for the natural broadleaf forest was lower than for artificial landscapes of Phyllostachys pubescens, Cunninghamia lanceolata, and Camellia sinensis. Therefore, to maintain sustainable development in the region, and especially to enhance protection for the broadleaf forest matrix, intense human activity and tourism should be reduced.

景观要素的斑块特征表明，在目前干扰强度下，阔叶林景观的连通性尚好，破碎化程度低；毛竹纯林、杉木纯林和茶园等人工或半人工经营景观的破碎化程度高，建议应该减少强烈的人类经营活动和旅游，特别要加强对阔叶林基质的保护，实现区域可持续发展。

The canopy interception will increase with the precipitation during at the beginning of rain, but it will keep stable later. The canopy interception quantity of six forest types is Mixed conifer forest, Pinus massoniana forest, Cupressus funebris forest, Conifer and broadleaf forest, Broadleaf forest and Shrubbery and grass land in order.There is much difference among the different species of the shrub and herbage.

林下灌草层不同的物种最大持水量有很大区别，在测定的物种中持水量最大的是糯米条，持水量最小的是柞木，糯米条的持水量接近柞木的3倍。6种森林类型林下灌草生物量从大到小依次是灌草地、马尾松林、针叶混交林、针阔混交林、阔叶林和柏木林；灌草层的持水量与其生物量具有密切关系，生物量多的持水量相应也多。

The results are as follows:The relationship between the precipitation and the stemflow is a linear regression. The stemflow of six forest types is Broadleaf forest, Conifer and broadleaf forest, Cupressus funebris forest, Mixed conifer forest, Pinus massoniana forest and Shrubbery and grass land in order.

结果如下：树干茎流量与降雨量成线性相关，回归方程达到极显著水平；6种森林类型的树干茎流量从大到小依次为阔叶林、针阔混交林、柏木林、针叶混交林、马尾松林和灌草地；不同树种间的树干茎流量差异极显著，影响树干茎流量的主要树体特征因子是冠型结构、胸径和平均冠幅。

The throughfall of six forest types is Shrubbery and grass land, Pinus massoniana forest, Cupressus funebris forest, Conifer and broadleaf forest, Broadleaf forest and Mixed conifer forest in order.The relationship between precipitation and the canopy interception is a power regression.

降雨初期，林冠截留量随着降雨量的增大而增大，但随着林冠吸水饱和，林冠截留量会逐渐趋于一个稳定范围。6种森林类型的林冠截留量从大到小依次为针叶混交林、马尾松林、柏木林、针阔混交林、阔叶林和灌草地。

After restoration 8 years Casta nopsiscarlessiivar.spinulosia,Symplocos satchuenesis and others evergreen broadleaf trees seeding increased. Pinus massoniana and Gordonia acuminata seeding decreased. After 11 years, Castanopsis carlessiivar.spinulosia, Symplocos satchuenesis and others evergreen broadleaf trees seeding were dominated.There was no Pinus massoniana seeding, and Gordonia acuminata seeding was very little .

结 果表明：(1)在恢复的前2年，马尾松、大头茶的幼苗占绝对优势，其次是川灰木、小叶栲的幼苗，其他树种的幼苗较少；恢复后的第8年，川灰木、小叶栲和其他树种的幼苗增加，马尾松和大头茶的幼苗减少；恢复后的第11年，川灰木、小叶栲和其他常绿阔叶树种的幼苗占优势，林下无马尾松幼苗，大头茶的幼苗也较少。

The increased NPP was primarily led by an advanced growing season for broadleaf evergreen forest, needle_leaf evergreen forest, and needle_leaf deciduous forest, whilst that was mainly due to enhanced vegetation activity during growing season for broadleaf deciduous forest, broadleaf and needle_leaf mixed forest, broadleaf trees with groundcover, perennial grasslands, broadleaf shrubs with grasslands, tundra, desert, and cultivation.

常绿阔叶林、常绿针叶林和落叶针叶林NPP的增加主要由生长季节的提前所致，而落叶阔叶林、针阔混交林、矮林灌丛、温带草原及草甸、稀树草原、高寒植被、荒漠以及人工植被NPP的增加主要来自生长季生长加速的贡献。
