The forest land circulation disputes appear in different forms and there are many outstanding issues in the legal process of law application.Forestry right system reform requires the application of the law of the forest land circulation disputes should be based on the principles that administrative disputes,civil damages and criminal liability are taken as a priority. Underlying causes of various problems in application of the law such as the ownership,validity of contract and the main issues in forest land circulation should be identified. Through the analysis of two aspects of the substantive law and procedural law,right solutions shall be worked out for dealing with transfer dispute of collective forest land.

According to greenhouse gas inventory,carbon emission sources,as well as carbon pools and carbon accounting methods were analyzed in this paper.Data from national greenhouse gas inventory submitted by Annex I parties and non-Annex I parties to the United Nations Framework Convention on Climate Change(UNFCCC) were collected,based on the net carbon removals by sinks or emissions by sources and their percentage in national greenhouse gas emissions by sources for land use change and forestry.Carbon estimating for land use change and forestry applied in China has a large gap compared to major developed countries.China should strengthen studies and improve its own forest inventory system in order to enhance China’s capacity in its compliance with international climate change agreements.

By using the report of the sixth forest resource investigation of Great Xing’an Mountains in Inner Mongolia in 2008,the biomass and carbon storage of the main forest types were estimated with the method of regression e-quation between biomass and volume.We obtained the following results:the total carbon storage of arbor is 348.89TgC in Great Xing’an Mountains,the carbon density is 43.43t/hm²,the carbon storage of undergrowth is 68.03 TgC,the soil carbon storage is 434.02 TgC and carbon storage of the larix gelini and the betula platyphylla accounts for 86.10% of the total carbon storage.The basic regularity on carbon density of different age structure is in such a high-to-low order:over ripeness forest,mature forest,near-mature forest,half-mature forest and young forest.Young forest,half-mature forest occupied 39.66% of the total carbon storage.The amount of CO₂ sequestration is 1279.26 Tg,the oxygen release totals 930.37 Tg,the total value of carbon is 418.668 billion yuan,the total value of release oxygen is 930.37 billion yuan.

Research plot was established in the Picea schrenkiana.var tianschanica forest in Xingjiang,northwest China.The spatial distribution patterns of dominant species of trees,shrub layers and spatial associations between Picea schrenkiana.var tianschanica and understory Lonicera caerulea were analyzed and explored.The results showed that the distribution of DBH of Picea schrenkiana.var tianschanica showed reverse “J” pattern.There were large differences involving spatial distribution among DBH classes.The Lonicera caerulea was almost randomly distributed across all studied scales except for the small scale(1-36 m).There was a positive correlation between Picea schrenkiana.var tianschanica and Lonicera caerulea at scales of 1-28 m.There was no obvious competition between overstorey and understorey and these two layers presented symbiosis or associated.There were no clear spatial associations among tree growth stages of Picea schrenkiana.var tianschanica except for the sapling and small trees.The changes of forest microclimate induced by tourists and grazing can possibly contribute to the increase of wind disturbance.

In this paper,the species richness and hygroscopic volume of plant leaves in different secondary succession stages of communities were determined and analyzed.The results indicated that the species richness ranged in average from 4.33 to 49.33 and the diminishing sequence was ACQO(49.33),AKLG(38.33),APME/APHC(28.67),ADI/ACV(17.00) and AEE(4.33).The hydrological function of the leaves of the plant communities was strongest in ACQO(12.93t/hm²),poorest in ADI/ACV(3.81t/hm²),and intermediate in the AKLG,APME/APHC and AEE communities.The hydrological function of the leaves was enhanced as the plant species richness increased.There was significantly positive correlation(r²=0.593,n=15,p<0.01)between the species richness and the hygroscopic volume.In woody layer,with species richness increasing,hygroscopic volume of leaves in corresponding communities decreased and then increased,and this layer gradually became the main contributor of rainfall interception. However,the hygroscopic volume and plant species richness in herbaceous layer did not reveal such a clear trend.

The vegetation quardat method is used to compare the ecological characteristics of recovery community and Disanthus cercidifolius var.longipes population at burned area to those at the non-fired area growing nearby at the same altitude in Dadongshan,Nanling Mountains.The results showed that the Disanthus cercidifolius var.longipes population recovered rapidly at the burned area,but the Quercus acutissima and Q.serrata have more important values,while the dominant species are Disanthus cercidifolius var.longipes,Pinus massoniana,and P.taiwanensis in non-fired area community.The similarity of Jaccard is 0.194,and Cody index is 29.00 showing the relplace rate of species is relatively high.The vegetation coverage,richness,the species diversity index of Simpson and Shannon-Wiener,and evenness of J_D and J_H at burned area are all lower than that of non-fired area vegetation,indicating that during the three years of early stage after fire,the community structure is flexible than that of non-fired community.Based on the diameter size structures,both the populations of Disanthus cercidifolius var.longipes at burned area and non-burned area have the same increasing trend,but the burned area has a lower population size.The height structure for population at burned area is much different from that at the non-fired area population.The results suggest that the population of Disanthus cercidifolius var.longipes at burned area naturally recoved rapidly,and some measures should be taken to ensure the survival and enlargement of Disanthus cercidifolius var.longipes population.

The dynamic of the main hydrological effect of three forest types(evergreen broad-leaved forest,Cunninghamia Lanceolata forest and Phyllostachys pubescens forest) was studied before(2006 year) and after(2010 year) freezing rain and snow disaster in Dagang Mountains of Jiangxi Province.The result showed the rainfall rate increased after the freezing rain and snow disaster within three forest types.Comparing the pre-disaster,the through-fall rate and the stem flow rate increased while the interception rate was reduced for the forest crown of three forest types in the post-disaster.The percentage change of the stem flow rate,the through-fall rate and the rejection rate of evergreen broad-leaved forest was the biggest,and Phyllostachys pubescens forest type was the smallest among three forest types.The thickness and the stock volume of ground litter increased,and the capacity of water-holding and interception of ground litter increased correspondingly after freezing rain and snow disaster in three forest types.The water physical characteristics and the hydrological effect of soil changed little after freezing rain and snow disaster,and it might be related with the cause that freezing rain and snow disaster did not directly destroy the ground litter lay in three forest types.
