    HUANG Guosheng, LIU Qian, PU Ying, SUN Xiangnan
    FOREST RESOURCES WANAGEMENT    2020, 0 (6): 1-5.   DOI: 10.13466/j.cnki.lyzygl.2020.06.001
    Abstract895)   HTML55)    PDF (926KB)(525)       Save

    Over the past six decades of exploration and development,China’s forest resources monitoring has made great progress.With the in-depth advancement of ecological civilization construction and forestry reform development,higher requirements have been placed on the timeliness,synergy,up-to-dateness of monitoring data and capabilities of information service.In the era of Big Data,a highly flexible “mosaic” concept is applied to build a new “mosaic” mode for forest resource monitoring.The original “sliced” patch data can be deeply integrated and shared in real time on the Internet,which significantly improves forest resources monitoring capabilities and information service.Constructed in accordance with the Big Data thinking,the National Forest Resources Smart Management Platform has the basic prototype of the Big Data Cloud Platform with forest resources monitoring “mosaic” mode.To adapt to the new requirements of ecological civilization and modernization of forestry,the platform should be extended and applied to various types of professional investigation and business applications,gradually establish a new mechanism,based on Big Data,for process monitoring and smart services of Internet plus data collection and business applications.Through data fusion,business digitization,data mining,and service collaboration technology innovation,the new mechanism will effectively enhance forest resources monitoring capabilities,improve the information service level and make new contributions to the high-quality development of forestry and grass industry.

    ZHANG Feng, PENG Zuodeng
    FOREST RESOURCES WANAGEMENT    2021, 0 (6): 52-58.   DOI: 10.13466/j.cnki.lyzygl.2021.06.009
    Abstract442)   HTML24)    PDF (1734KB)(515)       Save

    Based on the forest inventory data of Beijing from the seventh (2004-2008),the eighth (2009-2013) and the ninth (2014-2018),the continuous biomass expansion factor method was used to evaluate the dynamic changes of forest carbon stocks in Beijing during 2004-2018,and the carbon tax assessment method was used to estimate the economic value of the forest carbon sink in Beijing from 2004 to 2018. The results showed that: the forest carbon storage in Beijing was 7.09Tg from 2004 to 2008,9.43Tg from 2009 to 2013,and 15.39Tg from 2014 to 2018. The forest carbon density was 19.94,21.97,and 24.75t/hm2,respectively. The young forest accounted for the highest proportion of total carbon storage,accounting for 52.04%,47.64% and 53.42% in the three inventory periods respectively,while middle forest accounted for 23.05%,24.78% and 21.00% in the same period respectively. The economic value of forest biomass carbon sink in Beijing was 5.075 billion yuan between 2004 to 2008,5.725 billion yuan between 2009 to 2013,and 7.652 billion yuan between 2014 to 2018,the annual increment of economic value of forest biomass carbon sink in 15 years was 171.8 million yuan. The carbon stocks and carbon stock economic value of the forest resources in Beijing showed an increasing trend,but the proportion of young forest and middle forest was relatively high,and the carbon density of forests was low,so the scientific cultivation and management of the forest should be strengthened in order to continuously improve the function and value of the forest carbon sink.

    The integration and optimization for natural protected areas are important tasks for the construction of scientific and reasonable natural protected areas system and ecological civilization in the new era. According to ‘Guidelines on the establishment of a natural protected areas system dominated by national parks’,we determined the aims,objects,tasks and principles of integration and optimization for natural protected areas in China. At the same time,rules about system transformation,integration,optimization and division,as well as paths along planning,confirmation and practice had been refined for the integration and optimization of natural protected areas. In addition,we developed management styles by classification and division,and support systems of organization,team,capital and technology for natural protected areas after the integration and optimization. In conclusion,our study aimed to provide theoretical foundation and technical guidance for integration and optimization for natural protected areas,establish an integrated,standardized,and effective system with Chinese characteristics,so as to support and promote construction and management of natural protected areas.

    Based on the survey data of permanent sample plots at Wangyedian Forest Farm in Chifeng,the results of the stand volumes and species compositions were compared,which were calculated with three methods including the average experimental form factor(AEFF)Formula method,the AEFF and Mean Tree method,and One-Way Volume Table method,and linear relationships were found among the three different stand volume figures.In mixed stands,the inconsistent results of species composition were not significantly different at the 0.05 level with the sign test based on the classifications according to the coefficient difference of the dominant tree species(if they were the same,species less than 5% used).So,the average experimental form factors could be used to measure stand volume and species composition.To forest farmers or family forest farms,the AEFF Formula method might be more useful than the others.

    In order to further improve the efficiency of forest(plantation) vegetation extraction based on remote sensing image,this paper takes Landsat8 OIL as experimental data on the Google Earth Engine(GEE) platform,and uses supervised classification,support vector machine,maximum entropy model,random forest and decision tree classification based on the actual construction of the experimental area.Line extraction and comparison of various methods are made.On this basis,the area of Eucalyptus in Guangxi was extracted by decision tree,and the experimental results were validated by Unmanned aerial vehicle image and Google Earth Pro historical image.The experimental process and results show that remote sensing vegetation information can be extracted efficiently and quickly by using GEE.Among the five methods in this paper,the decision tree classification method achieves the best results.The overall accuracy and Kappa coefficients of Eucalyptus extraction in the experimental area are 0.82 and 0.85,respectively.At the same time,the area of Eucalyptus extracted by decision tree in Guangxi is in good agreement with the statistical data,which shows that the decision tree classification method constructed in this paper has a good consistency with the results of large area.Rapid extraction of vegetation cover information in complex mountainous areas is of reference significance.

    Hainan conserves one of the last tropical rainforests in China. The space-air-ground comprehensive data in tropical forest is not only the basis of the management of National Park of Hainan Tropical Rainforest,but also an important component to set up methodology of Terrestrial Ecosystem Carbon Inventory Satellite (TECISat) in China. From March 20,2020 to July 10,2021,we used National Forest and Grassland Inventory (NFGI) airborne platform to produce 20TB raw data and products that covered an area more than 6000 km2,including airborne large-footprint LiDAR,small-footprint LiDAR,visible and near-infrared image,and ultra-spectrum image. We also collected data from 170 forest plots,183 ground control points and 17 checking polygons. Combined with GF-7 and GEDI data,these data constituted the space-air-ground data covering National Park of Hainan Tropical Rainforest and surrounding area. The products showed that the horizontal and elevation accuracy of large-footprint LiDAR were better than 1m and 0.15m respectively. The horizontal and elevation accuracy of small-footprint LiDAR were better than 0.5m and 0.08m respectively. The elevation accuracy of DEM and height precision of CHM were 0.15m and 91.8% respectively. The horizontal accuracy of 0.2m DOM was better than 0.5m. The spectral and spatial resolution of ultra-spectrum image were 0.24nm and 1~2m respectively. This experiment provided high quality products and space-air-ground data for TECISat and national park management.
