The Chinese government also asks all provinces and regions to submit regular greenhouse gas inventories. Land use changes and forestry carbon sinks are an important part of the greenhouse gas inventories of all countries and provinces and regions within the country. Changes in land use and forestry are extremely complex and has high uncertainty. China has a vast, complex terrain with a huge geographic span from tropical to cold temperate, from humid areas to the arid and semiarid regions and China has various vegetation types, making the measurement of land use change and forestry carbon sinks extremely complex and difficult.To improve the accuracy, reliability, transparency and comparability of the countries compilation of national greenhouse gas inventories, the Intergovernmental Panel on Climate Change (IPCC) has published and updated the Compilation Guidelines for National Greenhouse Gas Inventories since 1995 for several times. The greenhouse gas sources are measured according to three tier methodology ranking from low to high. Among which Tier 1 carries out calculation through application of IPCC calculation methods and international parameters, Tier 2 carries out calculation through application of IPCC calculation method and country parameters, the Tire 3 methodology carries out calculation through application of country methods and parameters, including the establishment of a national carbon accounting system or model, and the application of satellite remote sensing and GIS, etc.Directing at land-use change and forestry, the major developed countries, such as Canada, Australia, USA, UK etc. in whole or in part adopt Tire 3 methodology, especially in Canada, Australia and other countries national carbon accounting system or model are established. China has submitted two national greenhouse gas inventories to UNFCCC, IPCC Tier 2 methodology is mainly used in land-use change and forestry, the conformability can be up to 50%. In compiling the provincial greenhouse gas inventories, similar methods are applied.In 2009, State Forestry Administration launched the "forestry carbon sink metering and monitoring system construction". The project was started in 2009 and was listed as one of the first four pilot provinces by the State Forestry Administration. Sichuan has huge forest resources in China, its forest areas accounting for 8.4% of the country's total forest areas and its storage accounting for 12% of the total national amount. Sichuan province has complex terrain, from the plains, hills, low altitude mountains, medium altitude mountains to high altitude mountains, covering China's major ecosystem types. Therefore it has typical meaning to choose Sichuan province as a demonstration province. The project aims to explore and establish a provincial or regional land-use change and forestry carbon accounting system in compliance with the highest level of IPCC methodology. The project is funded by the German Environment, Nature Conservation, Construction and Nuclear Safety Bureau (BMUB), National Forestry Administration and Sichuan Forestry Department.Project Objectives and Technical RouteProject objectives: taking Sichuan province as a demonstration province , based on the latest IPCC higher-level Guidelines methodology, to build a internationally recognized regional land-use change and forestry carbon measurement methodology (including the conversion between forest and other land types ) to meet possible future UNFCCC reporting and future intentional reporting requirements obligations, and to meet the information request by Sichuan Forestry to address climate change carbon sink forestry management policies, to improve China's ability to accounting land-use change and forestry carbon sinks.Technical Route: Based on the survey of forest resources, monitoring systems, integrating multi-source, multi-outcome data on forest resources survey, remote sensing data, climate data, through forest carbon sink metering data base research to establish regional forestry carbon sink/source measurement platform applying to different scales and objects with gradually improved measurement and accuracy. Applying measurement system to carry out quantitative accounting about forestry carbon reserves and the spatial-tempetial trends of carbon sink/source, and comparing and verifying related measurement methods.First, carrying out research on basic measurement data. ①carrying out informationization and standardization research on the data already have of forest, climate and remote sensing in the past forty years; ②carrying out the special research on the key elements such as biomass, forest soul organic carbon and physiological and ecological parameters.③ carrying out system. Second, carrying out research on measurement methods. ① taking the provincial statistical outcome as measurement, optimizing IPCC methodology recommended Tier 2 as the first level methodology of this measurement system; ② tinning the measurement down to the sample place and tree, carrying out systematic research on biomass, forest soil organic carbon measurement model, developing methodology based on the measurement of sample place and tree, that is the Tier 2 methodology of this measurement; ③ based on Tier 2 methodology ,integrating multi-source, multi-phase data such as remote sensing, climate data, physiological and ecological parameters and further extending to the measurement of spatial units to hill plots, developing Tier 3 methodology based on ecosystem process model.Major ActivitiesActivity III: (Figure 1).Tier 1 method tier 2 method tier 3 methodFigure 1 Carbon Measurement System FrameworkActivity IV:Table 1 Land Use Transition MatrixTransferred outtransferred in Woodland 非林地Forest land Open forest land Shrub Land Other Forest Farmland grass land Waters Unused land Construction landForest stand Economic Forest Bamboo ForestForest stand 10738959 15284 42212 76376 26409 113562 23458 0 0 0 0Economic Forest 58114 699096 6814 0 7025 14390 111907 0 6994 0 27977Bamboo Forest 15114 4762 319755 7370 13433 13382 0 0 0 0 0Open forest land 200919 12135 0 375426 18916 14125 0 0 0 0 0Shrub Land 38793 0 18922 15725 6809678 30344 8897 0 710 0 710Other Forest 343867 48986 36822 25510 374312 1882915 47021 0 0 5225 7837Farmland 246963 215096 61496 0 14617 109782 9528775 4862 14585 0 140987grass land 4842 0 0 0 4865 24911 8651706 0 0 0 0Water area 0 0 0 0 4865 0 801133 0 0 0 0Unused Land 4842 0 0 0 4865 0 5059338 0 0 0 0Construction Land 0 0 0 0 0 0 815708 0 0 0 0Figure 4 Land Use Change FigureTable 2 Models for Single Plant BiomassSpecies Position Form of the Equation(B = single forest plant biomass, kg d.m.)

Following picture is the screenshot of the methodology of outcomes of this project.世聯(lián)翻譯-讓世界自由溝通！專業(yè)的全球語言翻譯供應(yīng)商，上海翻譯公司專業(yè)品牌。絲路沿線56種語言一站式翻譯與技術(shù)解決方案，專業(yè)英語翻譯、日語翻譯等文檔翻譯、同傳口譯、視頻翻譯、出國外派服務(wù)，加速您的全球交付。 世聯(lián)翻譯公司在北京、上海、深圳等國際交往城市設(shè)有翻譯基地，業(yè)務(wù)覆蓋全國城市。每天有近百萬字節(jié)的信息和貿(mào)易通過世聯(lián)走向全球！積累了大量政商用戶數(shù)據(jù)，翻譯人才庫數(shù)據(jù)，多語種語料庫大數(shù)據(jù)。世聯(lián)品牌和服務(wù)品質(zhì)已得到政務(wù)防務(wù)和國際組織、跨國公司和大中型企業(yè)等近萬用戶的認可。
