本数据主要分析了乌拉特荒漠草原研究站（简称乌拉特站 http://urat.casnw.net/ ）实验样地的土壤理化特性，测定土壤含水量、土壤pH、土壤容重、土壤机械组成、土壤总碳、土壤总氮等。还包括了乌拉特站2018年至2020年植被植被调查中，0-10公分、10-20公分两层土层中植物根系生物量。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，在两区分别设置五个100 m×100 m的样地，每块样地内设置5个5 m×5 m的取样点，用土钻分别在取样点内随机取样三次，混匀后过2毫米筛取样带回，测定土壤含水量、土壤pH、土壤容重、土壤机械组成、土壤总碳、土壤总氮和0-20cm土层中植物根系生物量。", "ds_source": "

The survey time of this data set is from 2018 to 2020.\n
The experimental plot is divided into shrub area and herb area, and five 100m are set in the two areas respectively × 100 m sample plot, with 5 5 m in each sample plot × At the sampling point of 5 m, use a soil drill to randomly sample three times in the sampling point, mix well, and then take samples back through a 2mm sieve to measure soil water content, soil pH, soil bulk density, soil mechanical composition, soil total carbon, soil total nitrogen and plant root biomass in 0-20 cm soil layer.
