Results from a study on Sarcosperma laurinum communities from Qi-ao Island in Zhuhai city,Guangdong province,showed that:(1)61species of vascular plants belonging to 38families and 51genera were found in the Sarcosperma laurinumcommunity,with the floristic components of the community exhibiting a south subtropical property;(2)Analysis for the age structure of the community showed that the dominant species belonged to some stable populations,and the frequency index of the community was ABCDE,which was consistent with Raunkiaers frequency law;(3)For species diversity of the community,D=13.70,H =4.12,E=0.39,E′=0.82.Results indicated that the diversity and evenness indices were closed to those of a climax community from a typical subtropical evergreen broadleaved forest.

Periphyton and water samples were collected ten times from Gufu River in Xingshan County,Hubei Province,from December 2010 to December 2011.A total of twenty-eight genera were identified from the periphyton samples,and twelve water quality parameters were tested.Factor analysis was performed on the twelve water quality factors,with four major components,whose eigenvalues were greater than 1,selected.The first major component was accounted by TN and NO-3-N,the second by pH and CODCr,the third by PO3-4-P,TP and NH+4-N,and the fourth by Cond and TOC.The relationships between the nine extracted dominant water quality parameters and the main genera of periphyton were analyzed by CCA.According to CCA ordination,the sequencing of the correlations between the main water quality parameters and periphyton distribution was:CODCrpHTNNO-3-NTOCTPPO3-4-PCondNH+4-N.Monte Carlo significance test showed that the distribution of the periphyton taxa was most influenced by CODCr and pH,and less by TN,NO-3-N and TOC.Both pH and CODCr were strongly negatively correlated with each other.Most of the periphyton taxa in Gufu River were strongly correlated with CODCr,while only Chaetophora was fit for the low CODCr and slightly alkaline environment.TN and NO-3-N were strongly correlated,but both of them were negatively correlated with TOC.These three factors roughly classified the periphyton into two ecological groups:one preferring nitrogen,and the other carbon.Though usually a limited nutrient factor for algae,TP was not a dominant influencer on the distribution of periphyton in Gufu River.

Population characteristics of mistletoe in seven types of host trees of six communities in Laopinggang forest farm were studied from April to November 2012.Results showed that: As a whole,the ultimate distribution pattern of mistletoe was determined by the host trees.However,the distribution pattern of mistletoe on individual host trees was aggregated.In terms of quantitative characteristics,the numbers of mistletoe in host trees was Populus davidianaBetula platyphyllaAlnus sibiricaB.dahuricaTilia amurensis var.tricuspidata=Acer tegmentosumA.mono,and the mean number of fruit in a mistletoe was P.davidianaB.platyphyllaA.sibiricaA.tegmentosumT.amurensis var.tricuspidataA.monoB.dahurica.Red fruit and yellow fruit mistletoe were found on the same host species and the ratio of these two types was one to one.Genetically,the seeds of mistletoe showed excess propagation and their dispersal process had a close relationship with Bombycilla garrulus.Among these seeds,82% were found on fallen leaves,15% on shrubs and 3% on the trunk of host trees.It was concluded that the distribution pattern of host trees,composition and development degree of communities,living habit of seed dispersers and reproductive strategy of mistletoe itself played major roles in the development of the population.

Epimedium sagittatum has wide distribution and the large morphological variation,which makes it difficult to classify.In addition,great differences related to morphological traits and bioactive components exist between different populations with unstable quality.In this study,quantitative morphological characters and genetic diversity of 12 geographic populations of E.sagittatum were determined by a common garden experiment in the Wuhan Botanical Garden,CAS.The results showed there were significant differences in morphological traits.Based on AFLP data,the genetic diversity analysis demonstrated that population relationships were closely related with geographical distribution:Liuzhou population(LZ),Northwest populations(CL,HH,ZY)and Eastern and Central China populations(YT,WN,NF,HS,QZ,SG,LY,LT)were successively separated.But complicated morphological variations were shown by hierarchical cluster analysis of the main quantitative morphological characters and only part of the populations showed a certain relationship with genetic diversity.This study provides important information on the taxonomy and exploration of quality resources of E.sagittatum.

Soil and water conservation of five mosses were investigated in Naigu Stone Forest of Yunnan province.The five highest frequency mosses were Taxiphyllum taxirameum(Mitt.)

Dix.et P.Varde.Determination of biomass,pedogenesis quantity,saturated water adsorption rate and quantity of the five mosses showed that the average biomass ranged from 24.31 g/m2 to 103.78 g/m2,average saturated water adsorption rate ranged from 818.24% to 1462.02%(highest of 1659.27%),average saturated water adsorption quantity ranged from 216.92 g/m2 to 791.80 g/m2(highest of 1790.28 g/m2) average pedogenesis ranged from 47.32% to 111.58%(highest of 194.82%),and average pedogenesis quantity ranged from 9.01 g/m2 to 46.73 g/m2(highest of 110.17 g/m2).Experiments showed that the average saturated water adsorption quantity and average biomass of Anomodon minor subsp.integerrimus were greatest,791.80 g/m2 and 103.78 g/m2,respectively.Anomodon minor subsp. integerrimus exhibited the most significant correlation with soil water retention.Dry weight and fresh weight,biomass and dry weight,biomass and saturated water adsorption quantity,biomass and pedogenesis quantity,saturated water adsorption and pedogenesis quantity showed positive correlations.Therefore,the results indicated that the mosses had high ability to absorb and reserve water.The mosses showed a remarkable effect on pedogenesis,which is significant for landscape diversity and soil and water conservation in stone karst regions.

Mountain evergreen and deciduous broadleaved mixed forests in China are mainly distributed in the mid-subtropical mid-mountain zones.Mount Badagongshan(BDGS) is located on the northern end of the Wuling Mountains at the north rim of the mid-subtropical zone,and has a typical mountain evergreen and deciduous broadleaved mixed forest.To investigate dynamics of this forest,biodiversity origin and maintenance mechanisms in East Sichuan and West Hubei in 2010-2011,the Wuhan Botanical Garden,Chinese Academy of Sciences established one 25 hm2(500 m× 500 m) forest dynamic plot of subtropical mountain evergreen and deciduous broadleaved mixed forest in the Badagongshan(BDGS) National Nature Reserve according to the standards of the Center for Tropical Forest Science(CTFS).Here,we present the flora,community composition,structure,size class and spatial distribution based data collected from all woody(bamboo and liana not included) plants with DBH≥1 cm.Our results demonstrated that BDGS was a typical mountain evergreen and deciduous broadleaved mixed forest,dominated by pantropic distribution families(24.50%) and northern temperate distribution genera(24.56%).There were nine rare and endangered wood plants.We classified 186556 individuals into 53 families,114 genera and 238 species(94 evergreen and 144 deciduous).Dominant species were from the families of Fagaceae,Ericaceae,Lauraceae and Theaceae.There were 38 species with 1000 individuals(63.16% evergreen).In total,103 rare species( 25 individuals) accounted for 43.28% of all the woody plants.The forest strata was divided into a canopy layer dominated by Cyclobalanopsis multinervis and Fagus lucida,an understory layer dominated by Rhododendron stamineum and Litsea elongata,and a shrub layer dominated by Eurya brevistyla and Symplocos anomala.Abundant(1000 individuals) and rare species were mainly from the shrub layer.Limited by growth form,the plot had a fairly small mean DBH(5.41 cm) and was dominated by small sized individuals(68.40%).The size class of five dominant trees was reverse J.
