Global Forest Resources Assessment 2010 and Enlightenment to China

Abstract: The contents,indicators,methodology and key findings of global forest resources assessment(FRA)2010 organized by FAO are introduced.The national forest resources assessment,national report and the contribution to global analysis of FRA 2010 are summarized.In particular,proceeding from the realistic situation in China,the urgent issues on national forest monitoring and statistics are analyzed.The approaches for enhancement of the timeliness and authority of the national figures,and strengthening the ability of answering the global focuses related to global climate change including SFM evaluation,forest carbon accounting and REDD plus are also identified.

Dynamics of Net Production of Chinese Forest Vegetation Based on Forest Inventory Data

Abstract: According to the net primary productivity data of 1?266 samples about different forest types in China,the functional relationship between biomass,volume,community growth and annual litter fall about Chinese major forest types were established and the net production and dynamic changes about Chinese forest ecosystems were studied by using the data from six NFIs of China from 1973 to 2003.The results showed that the net production of Chinese forest vegetation was 1?360.64×106t/a during the 6th NFI,and the average net primary productivity was 9.53 t/hm2.a.The net production was composed mainly of young and middle-age forests and had some differences between different regions with the net production higher in northeast and southwest,and lower in other regions.From 1973 to 2003,the net production of Chinese forest vegetation increased from 790.13×106t/a to 1?360.64×106t/a.The net production was the lowest before 1970s and then increased gradually.Whereas the average net primary productivity of Chinese forest vegetation was higher before 1970s and decreased until the end of 1990s and then increased again.

Population Classification and Sample Structure on Modeling of Single Tree Biomass Equations for National Biomass Estimation in China

Abstract: The population classification and sample structure on modeling of single-tree biomass equations for national biomass estimation in China was studied in this paper.Firstly,combining the classification of eco-geographic region and administrative region,a scheme of population classification on modeling of single-tree biomass equations was presented,which is mostly compatible with the population classification on modeling of single-tree volume equations,including 34 tree species or species groups,6 large-scale geographic regions,and a total of 70 populations.Secondly,based on the analysis of variation coefficients derived from one-and two-variable tree biomass models fitted with available tree biomass data of several tree species,it was concluded that prediction precision of tree biomass models could be defined as more than 95%,and at least 150 sample trees are needed for a regional model which should be selected in equal numbers for each diameter class,i.e.,not less than 15 trees in each of 10 diameter classes.Finally,by using the 7th National Forest Inventory data,the sample structure of each population was determined,that is,all the sample tree numbers of 70 populations were specified by province and by diameter class.The results will provide a practical reference for the establishment of generalized single-tree biomass models in China.

Basic Ecological Characteristics of the Three-Rivers' Source Area and Design of the Nature Reserve

Abstract: The ThreeRivers' source area refers to the source catchment of the Yangtze River, the Yellow River and the Lancang River It is located in the hinterland of QinghaiTibet Plateau and forms a unique ecosystem in the world. It has been described as the "Water Tower of China" A large salvage nature reserve in the ThreeRivers Source area is very important and urgent, which will safeguard the ecological security of three rivers' drainage area and boost the sustainable development of the threerivers' source area The paper puts forward a new way to build the nature reserve networkIn this paper, the source area has been viewed as an integrative biogeography area. And it concludes that a biota nature reserve network can be built in the source area through planning and management of biota The paper recommends the theories of landscape ecology be used and the population viability analysis be conducted Then the paper establishes the source naturereserves net from the area coverage by using the landscape planning and GIS analysis, analyses the area and the shape of the corezone of every netnode and the process and technology of cennecting the corridors with nodes

Forest Ecosystem Health Assessment Indicators and Methods

Abstract: In this paper we introduce the definition and characteristics of forest ecosystem health. The stability,sustainability and integrity are forest ecosystem health assessment's objectives and criteria,and select a series of variables including forest ecosystem structure,organization,biodiversity,NPP,etc.as forest ecosystem health assessment indicators.And the conceptual model to assess forest ecosystem health is put forward.The comprehensive mathematical statistical methods are applied to quantify forest ecosystem health,and forest ecosystem health is managed dynamically on temporal and spatial-scales.
