英文标题 Grassland survey data in Qinghai Region from 2021 to 2024
中文摘要 本文件包含了2019-2020年青海片区草地调查数据,调查地点主要位于青海省果洛藏族自治州。数据分为三个表格:样地信息表、植被调查表和土壤理化性质表。样地信息表记录了经纬度、海拔、土壤类型等关键地形因素,部分参考指标尚未全面获取,并已在表中进行了标注。需要特别注意的是,数据中以“QH-××-F”开头的样点为辅助样点,作为“QH-××-Z”样点的参考,这些辅助样点并未进行植被调查和土壤理化数据采集,因此不包含相关数据,请科研工作者留意。植被调查表提供了物种信息,样方面积大小为0.25m2,土壤理化性质表主要包括土壤全氮、全磷、有机碳、铵态氮等指标。后续可以基于植被调查表进行生物多样性分析,并结合土壤理化性质和样地信息表,开展更为全面的影响因素分析。此外,也可以将此数据整合,作为青藏高原大面积尺度遥感数据的参考,供进一步研究使用。
英文摘要 This document contains data from the 2021-2024 grassland survey in Qinghai Area, which is mainly located in Guoluo Tibetan Autonomous Prefecture, Yushu Tibetan Autonomous Prefecture, and Haixi Mongolian Tibetan Autonomous Prefecture in Qinghai Province. The data were divided into five tables: sample site information table, vegetation survey table, aboveground biomass table, soil physical and chemical properties table and microbial diversity table. The Sample Plot Information Table records key topographic factors such as latitude, longitude, elevation, and soil type; some reference indicators are not yet fully available and have been labeled in the table. The vegetation survey table provides species information, cover, height and clump number, etc. Sample area sizes were 0.25m2, 1m2 and 4m2, as described in the data content. The soil physicochemical property table mainly includes soil total nitrogen, total phosphorus, organic carbon, ammonium nitrogen and other indicators. Subsequently, biodiversity analysis can be carried out based on the vegetation survey table, and a more comprehensive analysis of influencing factors can be carried out by combining soil physicochemical properties, microbial biodiversity and terrain elevation. In addition, this data can also be integrated as a reference for large area-scale remote sensing data on the Tibetan Plateau for further research.
