The data comes from plant community data from different groundwater burial depths in the Qira Desert Ecosystem, Xinjiang in 2024. Three representative groundwater burial depth areas of 2.5, 4.5 and 11.0 m were selected based on groundwater conditions in the study area, and corresponding sample plots and quadrants information were established. The spatial location of the sample plot is matched with groundwater burial depth data, and the plant species information is sorted out based on survey records and plant classification data, and finally the species composition data of plant communities under different groundwater gradients is formed.", "ds_quality": "
Unified data recording and collation standards are adopted for sample sites with different groundwater burial depths. Plant names and family information are checked through classification data, and sample plot coordinates are checked against groundwater burial depth information. After data entry, duplicate records, missing values and abnormal values are checked, focusing on checking whether the coverage is within a reasonable range, whether there is a negative value in the density, and whether the sample plots correspond correctly to the species records. Abnormal data will be returned to the original data for review, and no unfounded modifications will be made to ensure the accuracy, integrity and traceability of the data.", "ds_ref_way": "", "ds_abstract": "
This dataset records the species composition and structural characteristics of plant communities under different groundwater depth conditions in the Cele Desert Ecosystem, Xinjiang in 2024. The study area is located on the southern edge of the Taklimakan Desert, with three groundwater burial depth gradients of 2.5, 4.5 and 11.0 m to record plant species composition and community structure information under different groundwater conditions. The data mainly includes indicators such as plot and plot numbers, groundwater burial depth, plot latitude and longitude, plant Chinese names and Latin scientific names, families, life forms, species appearance, coverage, density and relative coverage, involving Camel thorn, flower wood, reed, licorice expansa and other desert plants. This dataset can reflect the differences in desert plant species composition and community structure under groundwater burial gradient, and can provide basic data for studying the impact of groundwater changes on desert vegetation distribution, community structure and plant diversity, as well as the groundwater-vegetation relationship in arid areas.\r\n
Data were organized according to different groundwater burial depth gradients, including three groundwater burial depth levels of 2.5, 4.5 and 11.0 m. The main fields include area, plot number, groundwater burial depth, plot latitude, plot longitude, plant Chinese name, plant Latin scientific name, family, life form, species occurrence, coverage, density and relative coverage, etc. Each record corresponds to a specific groundwater depth and a plant species in the sample, and can be further used to calculate indicators such as species richness, dominance, and community diversity.", "ds_time_res": "", "ds_acq_place": "Celle County, Hotan Prefecture, Xinjiang Uygur Autonomous Region, Celle Desert Ecological Area, southern edge of Taklimakan Desert", "ds_space_res": "", "ds_projection": "", "ds_process_way": "
The original records are first classified according to groundwater burial depth and plot number, and a data structure of \"groundwater burial depth-plot-species\" is established. The Chinese names, Latin scientific names, families and life forms of plants are unified, and the latitude and longitude are uniformly expressed in decimal degrees. Coverage is uniformly expressed as percentage, and density is uniformly expressed as plant·m ².
