    The scale of development of China's nature reserves exceeds the world average,but the pressure on biodiversity conservation increases,which has resulted from the low management effectiveness.Nature reserve management objects are different from those of other regions,mainly based on natural ecosystems. Management effective evaluation shall focus on the effectiveness of population security,conservation,community harmony and three levels of achievement of objectives. The evaluation system design emphasizes the management infrastructure,mechanisms,decision-making,implementation,monitoring of five key aspects. and includes 16 indicators and 44 assessment factors.1394 national and local nature reserves are selected for the application,and initial results achieved.

    In order to meet the needs of the watershed forest management practice in Liupan Mountains,based on the continuous forest inventory data from 120 fixed sample plots in this area,the law of watershed forest canopy density impact on the growth of the undergrowth shrub and herb was analyzed,the related mathematical models were established,and an objective stand vertical structure of watershed forests in the area was put forward in this study.The results show that,1)canopy density has impact on the growth of the undergrowth plant,the undergrowth shrub and herb coverage decrease with the increasing of canopy density;2)a distinct arbor-shrub-herb vertical structure can be formed when the canopy density is kept in the range of 0.5~0.8,and accordingly the relationship between ecological and economic functions will be well coordinated;3)the objective stand vertical structure in the area shows that the canopy density is kept in the range of 0.5~0.8,each shrub and herb coverage kept in the range of 35%~45%.Therefore,the result provides scientific support for the structure regulation of the watershed forest stands.

    Based on investigation data from a permanent secondary forest plot of 1ha in Mopan Mountains,Jilin city,the structure of Tilia mandshurica population was analyzed.Ripley's K function was used to analyze spatial patterns of T.mandshurica population at different growth stages (saplings,small trees and big trees).The results showed that DBH structure of T.mandshurica presented a reverse “J” distribution and small age individuals accounted more.The spatial pattern of T.mandshurica population was clump for all stems,saplings and small trees,but random for big trees; spatial associations between different stages were repulsed .It indicates that seed dispersal and regeneration mechanism was a key factor to spatial pattern.

    Based on the branches and leaves of artificial Xanthoceras sorbifolia population in Dingxi district of Gansu,5 phenotypic traits were investigated for 59 X.sorbifolia samples in trial area.Phenotypic variation was studied by using variance analysis and variation coefficient,between various individuals,different sections of branch and different branch types.The results showed that there was extremely significant difference (P<0.01)among various phenotypic traits of leaves and there was greater variation among different individuals of X.sorbifolia in trial area,but the variation degree of various phenotypic traits was different and the sequence of variation coefficient of traits is as follows:length of leaflet(18.70%)> width of leaflet(17.96%)> length of compound leaf(17.04%)> pair number of leaflet(14.14%)> amount of leaflet(13.07%); between different sections of branch,the phenotypic traits of leaves had no obvious differences and coincident change law,and only the indicators of width of leaflet,pair number of leaflet and amount of leaflet had very significant differences(P﹤0.01); between the different branch types there was obvious differences among phenotypic traits of leaves,and had significant differences (P﹤0.05)or very significant differences(P﹤0.01)except for pair number of leaflet.Besides,the type of branch was closely correlated to the ability of resisting disease and insects of X.sorbifolia,and the individuals with velutinous scarlet branch strongly resisted diseases and insects,whereas the individuals with brown branches but no velutinous had very serious diseases and insects,these characteristics can be treated as an important indicator for preliminary selection of fine individual of X.sorbifolia.

    The understory plant species diversity and soil physical and chemical properties were investigated,and their relationship of the Casuarina equisetifolia coastal protection forest with different stand structure explored in Haikou.Results showed that the understory plant species composition of the Casuarina equisetifolia forest was simple,with 52 species attributed to 29 families and 46 genera.The species richness index(S),Simpson index(D)and Shannon-wiener index(H')were low,and species richness decreased with increase of human disturbance.The soil water content,soil nutrients including organic matter,available potassium and available phosphorus were very low.The results of correlation analysis showed that soil organic matter,available nitrogen and available potassium were significantly correlated with S,H' and D.The strong correlations between soil properties and plant species diversity demonstrate that organic matter,available nitrogen and available potassium are the most important soil factors impacting understory plant species diversity for the Casuarina equisetifolia coastal protective forest.

    The relationship between the growth of Platycladus orientalis(GPO)and climatic factors(CF)was analysed by the canonical correlation analysis method in Beijing.The results showed that Platycladus orientalis was a kind of tree which responds sensitively to CF.There were mutual effects among CF,and CF effect GPO together.The annual average temperature and the average temperature from March to May in previous year were the dominant meteorological factors affecting the diameter growth of Platycladus orientalis.The increment of height was affected mainly by the annual precipitation and the average precipitation from June to August in previous year.And the average precipitation and average temperature from December of previous year to January of current year were the important factors influencing the volume growth.It was concluded that the most important CF that affects the GPO were the temperature and the precipitation.

    The damage of Great gerbil(Rhombomys opimus)to Cakcayr (Haloxylon ammodendron)natural forest distributed on Alxa desert in Inner Mongolia of China was surveyed using the method of plugging hole and checking opening hole in autumn and spring from 2009 to 2010.Multiple regression method was used to analyze the relationship between Great gerbils abundance and environmental factors.Meanwhile,damage levels of Great gerbils were overlaid with Cakcayr forest distribution map (1∶2200000)to divide 4 grades based on damage conditions by 3S technology.The results indicated that Great gerbils abundance was positively correlated with Cakcayr biomass,soil moisture and monthly precipitation,negatively correlated with Cakcayr density.The correlation of Great gerbils abundance with monthly precipitation was the most significant one among all of factors.During two years,Great gerbils damaged areas were mainly distributed in the north and east of Alxa desert,and damage in autumn was more serious than spring.The "3S" technology not only reflects cakcayr forest distribution and Great gerbils damage levels accurately,but also provides an effective tool for monitoring and comprehensively managing pest rodents in Cakcayr forest.

    Based on some meteorological factors, prediction was made on the incidence rate of forest diseases,mice and pests by simple linear regression(SLR),multiple linear regressions(MLR),simple non-linear regression(SNLR)and BP neural network(BP).The results show that the determination coefficient(R2)and root mean square error(RMSE)of MLR are better than that of SLR,the R2 and RMSE of BP are better than that of SNLR.According to the quality of models,BP model is the best of all,and SNLR is better than MLR and SLR.The conclusion is that the relations between meteorological factors and incidence rate of forest diseases,mice and pests are not linearity,non-linear model could effectively explain the incidence rate of forest diseases,mice and pests.
