中国天然森林土壤碳储量分布图-东北森林土壤碳储量分布图（2011-2015）

本数据集包含东北地区森林1米深度土壤碳储量和最大固碳潜力的空间分布网格数据。该数据集基于国家重点基础研究项目“典型天然森林和草地土壤固碳功能与固碳潜力研究”2012-2015年获取的1450个样点调查数据（土壤碳密度、土壤类型、经纬度、地形、气候和森林结构等），采用随机森林方法建立模型，进行空间插值获得土壤空间分布图。数据集覆盖东北地区所有森林，经纬度范围115.4889E ~134.9791E, 38.71714N~53.52916N.栅格大小0.01178363°；采用WGS84经纬度投影，数据量10M。

This dataset contains spatially distributed grid data of soil carbon storage at 1-meter depth and maximum carbon sequestration potential of forests in Northeast China. It is developed based on 1450 sample survey records (including soil carbon density, soil type, latitude and longitude, topography, climate, forest structure, etc.) collected from 2012 to 2015 under the National Key Basic Research Program titled "Research on Soil Carbon Sequestration Function and Potential of Typical Natural Forests and Grasslands". A random forest model was established to perform spatial interpolation and generate the soil spatial distribution map. The dataset covers all forests in Northeast China, with a geographic extent of 115.4889°E ~ 134.9791°E, 38.71714°N ~ 53.52916°N. The grid size is 0.01178363°, using WGS84 geographic coordinate system as the projection, and the total data volume is 10 MB.
