    Based on the the volume and biomass distribution of the Larixprincipis-rupprechtii Plantations,the regressive models were established between the trunks volume and biomass.The results indicated that along with the growth of the trees,when the trees reach a certain height,high growth slowed and the average annual volume growth increased;The biomass of organs is in descending order of trunk>roots >branches >leaves,which presents an increasing trend with the increase of the age.There was close correlation between trunk biomass and its corresponding volume and the regressive equations had remarkable precision available for conversion between biomass and volume of the Larixprincipis-rupprechtii plantations.

    Pinus massoninana secondary plantation is one of the major single species forest plantations in southern China.Our objective is to expound the variation of the understory community structure in the development process of the major single species forest plantations,to provide a basis and reference for the vegetation ecological improvement of the plantations.We adopted the method of space substitute time,sited a standard plot in the plantations of each age stages to study the species diversity in the communities.Investigation was conducted for different stages of Pinus massoninana plantations,which showed that there were 108 kinds of plants species,56 families under 91 genera in Zijin Mountain National Forest,Hengshan County,Hunan Province.Loropetalum chinensis,Quercus fabri,Radix Syzygii,Gardenia jasminoides and Imperata cylindrica,Schizachyrium scoparium,Lophatherum gracilie and Woodwardia japonica have a greater advantage in the whole community.Before the mature forest (15 years),the index value of the entire community and its diversity is very volatile.New species of wild trees appeared after the mature forest (15 years),while the index value of the whole community tends to bestable.Throughout the evolution of the communities,the species similarity is lowest(Sm of 0.158) between communities of old growth forest (25 years) and young forest (5 years),β diversity the most,reflecting the young forest (5 years) is the most unstable community.

    Based on the survey data of a 0.36 hm2 plot in Jinyunshan National Nature Reserve,and by using the uniform angle index,neighborhood comparison and mingling degree,this paper analyzed the spatial structural characteristics of Pinus massoniana and Broad-leaved tree mixed forest in the Reserve.There were 11 populations in the tree layer of the forest,among which P.massoniana and Broad-leaved tree mixed forest had the obvious advantage in population density and basal area,being the typical coniferous forest.The average mingling degree of the forest was 0.817,single species was rarely gathered with mixed forest at a higher degree The neighborhood comparison distribution of the mixed forest was uniform with the stand being stable.Individual associated broad-leaved species,for example,Adinandra bockiana,Neolitea aurata,Euryanitida korthals and Daphniphyllum oldhami,was pressed in the stands.The average mingling degree was 0.485,the spatial pattern of the stand was of random distribution,and the distribution is uniform.

    A field plot sampling method was employed to investigate community niche of Castanopsis hystrix forest in Wantian,and parameters of niche breadth (Levins index,Hurbert index,Feinsinger index),niche similarity,niche overlap were calculated to show community characteristics of 20 dominant species when the ecological suggestions of result were analyzed.The result showed that with the Levins index,Hurbert index and Feinsinger index,the result of niche breadths of the dominant species were almost the same;Castanopsis hystrix,Psychotria rubra and Asplenium normale niche breadth value being biggest proves that adaptive capacity to community's environment and the ability to use resources is the stongest;The niche similarities between dominant species population in Castanopsis hystrix forest in Wantian were much greater,and 109 sets for Castanopsis hystrix forest had the niche similarities(Cih) greater than 0.4,accounting for 57.4%,which shows that dominant species population in Castanopsis hystrix forest used similarly resource space and similarly ecological factors they occupy.The niche similarities between dominant species population increased with niche breadth.Between Castanopsis hystrix and Schefflera pauciflora,Psychotria rubra and Ardisia quinquegona,similarity values(Chi) were 0.7097 and 0.7416,respectively.The niche overlaps between dominant species population in Castanopsis hystrix forest in Wantian were much lower,which suggests less fierce interspecies competition in the forest,representing a stable community of the Castanopsis hystrix forest in Wantian.

    Based on the field survey of 42 wetlands sites that could be constructed as wetland parks in different districts and counties in Beijing,the main types of water resources for the ecological water demand of wetland park in Beijing were analyzed from the viewpoint of the concept of ecological water demand.The wetland ecological water demand of wetland park was portioned into three different levels from the viewpoint of minimum and favorable ecological water demand by the investigation of field water resource supplementation and indemnification of the ecological water demand of wetland parks in Beijing,which was analyzed from the point of utilization of recycled water.The results showed that the main water resource of the ecological water demand of wetland park in Beijing was comprised of four types of water including the natural precipitation,the underground infiltration,the transit water and recycled water;Of the 42 wetland sites,39 wetlands operate under the conditions of full enough water resource that could meet the minimum ecological water demand based on the amount of water supplementation from the local area,comparing those operating under a favorable ecological water demand,which reached 11.However,the amount of water resource of 3 wetland sites does not meet the minimum ecological water demand because of the insufficient supplementation from the local area;In general,the efficient utilization of recycled water in Beijing makes the minimum ecological water demand accessible and guarantees the basic use of water resource in wetland parks.

    Differential rent of ecological economy is the major basis for calculating forestry ecological efficiency.Differential rent I of ecological economy reflects the natural productiveness of forestry,while differential rent Ⅱ is determined by ecological demand of the region where the forest is located.The adjustment coefficient of ecological supply capability (differential rent I of ecological economy) and the adjustment coefficient of economic price of ecological demand (differential rent Ⅱ of ecological economy) can be treated as the comprehensive price adjustment coefficient for each region's ecological economy.

    We chose the walking trail,tourist road and the village where no tourism activities would reach as our research places based on the different forms of tourism activities in Pudacuo.By recording the bird's species,number,birds` feeding distance,the corresponding passenger flow volume and traffic volume in different period of time,then we can analysis the connection 1between recreational disturbance and bird's diversity and feeding distance.The result showed that bird diversity changes from the different intensity of disturbance.Among the three circumstances,bird's diversity in village is the highest,the second is in tourism road,and diversity in walking trail is the lowest.We found that passenger flow volume has significant negative impact on bird's diversity,while traffic volume has only weak effect.The impact of passenger flow volume on bird `s feeding distance varied upon different species of birds,it has a bigger effect on snipe birds and white wagtail (Motacilla alba) than swimming birds and corvidae birds.By studying the impact of different types of tourism activities on bird's diversity and bird's feeding distance,we can give more practical and scientific suggestions to improve the operation and management of Pudacuo.
