This data comes from the field survey and sampling of the natural camel thorn population in the arid areas of northwest China during July 1-August 28, 2025. According to the Flora of China,\"Atlas of Vegetation of China\" and species distribution, 15 representative sample sites with camel thorn as the dominant species were selected in the south and northern margins of the Tarim Basin, Turpan Basin, southern margin of the Junggar Basin and western Hexi Corridor. Three 10 m×10 m quadrats were randomly set up in each plot to investigate the coverage, plant height and number of plant clusters, and 3 Alhagi were randomly selected to collect leaves, thorns, stems and roots of 0 - 100 cm. After drying at 80 ℃ to constant weight, the biomass of each organ was determined. Soil samples were collected at 0 - 20, 20 - 40, 40 - 60, 60 - 80 and 80 - 100 cm layers for determination of water content, available nitrogen, available phosphorus and organic carbon.", "ds_quality": "
All sample plots adopt a unified quadrat setup, plant sampling and soil stratified collection process. Plant samples are uniformly dried at 80 ° C to constant weight; soil moisture content is determined by drying difference method, alkali solution diffusion method is used for alkali-hydrolyzed nitrogen, effective phosphorus is used for NaHCO extraction-molybdate/ascorbate blue method, and organic carbon is determined by K ˇ Cr ˇ O-H ˇ SO digestion titration method. After data is produced, check the plot numbers, quadrants, soil layers, units, missing values and abnormal values to ensure data consistency and traceability.", "ds_ref_way": "", "ds_abstract": "
This dataset is derived from the population survey and plant functional characteristics determination of Cami spines in different desert areas of Xinjiang (2025.7.1 - 8.28). It aims to reveal the spatial differences in Cami spines population structure, biomass allocation and multi-organ functional characteristics. The dataset contains 12 worksheets and 175 sample plot level statistical records. Population and biomass data cover a total of 15 plots from S1-S15, including population coverage, height, number of clusters, leaf, thorn, stem and root biomass, as well as the biomass allocation ratio of each organ and root-to-shoot ratio. Organ ecological stoichiometry data include the carbon, nitrogen, phosphorus contents and their stoichiometric ratios of leaves, thorns, stems and roots. Leaf functional characteristics include specific leaf weight, leaf thickness, leaf tissue density, nitrogen content per unit mass and unit area, vein density, maximum stomatal conductance and stomatal characteristics of upper and lower epidermis. Anatomical characteristics include leaf epidermal cell wall and cuticle thickness, stomatal length and density of thorns and stems, and stem vessel diameter, pit area and pit density.
