Qilian Mountain comprehensive observation network: Plant diversity monitoring in Qilian Mountain (plant survey data - 2018)- A Big Earth Data Platform for Three Poles

The dataset consists of three parts: part 1, survey data of plant plots from 7 tributaries of the upper Shiyan River Basin and the Qingtu Lake in the Qilian Mountains from August 16,2018 to August 30 ,2018; part 2, survey data of plant plots in the main tributaries of Heihe River and Shule River Basins from 2018.9.25 to 2018.10.3 ; part 3, survey data of plant plots in Qinghai Lake and Heihe River Basin from August 18, 2013 to August 8, 2018. The first part involves the growth characteristics and quantity information of herbs, shrubs and trees; the second part mainly investigates trees and only gives a rough estimate of herbs; the third part mainly investigates meadow vegetation.

The three-part survey sets up plots based on vegetation types, and at least 3 plots (sub-trees, shrubs, and herbs) are selected for each plot. Among them, the herbaceous aspect product is 1m×1m or 0.5m×0.5m; the desert shrub-like product is 10m×10m; the forest shrub area is 2m×2m; the shrub shrub area is 4m×4m; the arbor-like aspect product is 20m. ×20m. Plant community survey in each sample: the arbor sample survey mainly investigated the number of species, species abundance, 20 arbor trees per wooden ruler (including plant height, DBH, crown width, live branch height), within the sample The diameter of all arbor; the shrub-like method mainly investigated the species number, abundance, shrub crown and shrub plant height of all shrubs; the herb sample mainly investigated the number, degree or coverage of the herbaceous species, average plant height, total coverage, Aboveground biomass.

File naming and required software

Data file naming method and usage:
The data file is an excel file (.xlsx format), the herbal sample data is placed in the “herbal sample” table, the shrub sample data is placed in the “shrub sample side” table, and the arbor sample data is placed in the “arbor sample” table.
Description of the data table header:
Reporter: Data compilation and filling personnel
Date of investigation: sample survey time
Research area: According to Qilian Mountain Basin
Ecosystem type: According to vegetation, it is divided into forest, shrub, grassland, grassland and desert.
Type of vegetation (name of dominant species): estimate at the time of the survey
Sample location: specific tributary or place name
Longitude, latitude, altitude: using handheld GPS and mobile phone built-in GPS
Sample number: According to the plotting time and vegetation, the plots are prepared from 1, and the plots without vegetation survey are not recorded.
Sample number: label according to different type
Sample size (m2): sample area, square meter
