本数据主要调查了乌拉特荒漠草原研究站（简称乌拉特站 http://urat.casnw.net/ ）实验样地的植被生长情况，该实验样地植被群落主要由以红砂-珍珠为优势种的灌木群落和以沙生针茅为优势种的草本群落组成。调查的主要指标是物种数、分盖度、高度、密度、地上生物量和凋落物生物量。本数据集调查时间为2018年至2020年（每年8月份调查获得）。\n
将该实验样地分为灌木区和草本区，选择典型和代表性植物群落，在灌木区和草本区分别设置五个100 m×100 m的样地，采用对角线法设置样线清查样方内所有灌、草植物种类组成，在样地内系统设置5个5 m×5 m的灌木样方，5个1 m×1 m的草本样方。", "ds_source": "

<p>  The vegetation survey is conducted according to various community types in different zones. The vegetation surveyed mainly includes shrubs and herbs.\n <p>  The data is accurate. Five survey sample points are selected in each region, and five survey districts are randomly selected for each sample point. The number of survey repetitions reaches the scientific counting convention.\n <p>  This data mainly investigates the vegetation growth of the experimental sample plot of Ulat Desert Grassland Research Station (hereinafter referred to as Ulat station). The vegetation community of the experimental sample plot is mainly composed of shrub community with red sand pearl as the dominant species and herb community with sand Stipa as the dominant species. The main indicators of the survey are the number of species, coverage, height, density, aboveground biomass and litter biomass. The survey time of this data set is from 2018 to 2020\nThe experimental plot was divided into shrub area and herb area. Typical and representative plant communities were selected, and five 100m were set in shrub area and herb area respectively × For the 100 m sample plot, the diagonal method is used to set the sample line, check the composition of all shrub and grass plant species in the sample plot, and systematically set five 5 m samples in the sample plot × 5 m shrub quadrat, 5 1 m × 1 m herbaceous quadrat.
