AB  - This data is the vegetation and soil data set of northeast continuous permafrost region in 2014. The data includes three tables: (1) arbor (per tree scale) (2) shrub herb (shrub layer, herbaceous layer vegetation sample survey data) (3) soil (fresh and dry weight record table of soil) the standard sample method was selected from July to August 2014 with flat and open terrain, representative and perennial freezing 30 soil sample plots were used to establish standard forest investigation sample (20 × 20 m) to record plant species, trees and DBH (diameter at breast height) and other indicators. Three 2 × 2m shrub quadrats were set up along the diagonal line in the woodland quadrat to record the shrub, grass species, trees, coverage, etc. the biomass of living plants and litter in the whole sample plot was taken from the harvest side, weighed (accuracy 0.1g) and dried. At the same time, in the shrub grass sample plot, the standard soil profile of leveling ground was excavated to the frozen soil layer, and the sample was obtained by using a ring knife with a volume of 100 cm3. The sample was weighed (accuracy 0.1g), dried, and then weighed dry weight to obtain its bulk density data. For vegetation samples and soil samples, please refer to the article
