Abstract：
In order to investigate the soil-related reason of vegetation growth in the urban green belts of Dezhou City, the authors conducted a systematic soil sampling survey of the green belts in the urban core area in June, 2024, including Tianqu Road, Dongfeng Road, East and West Chahe Avenue, Changhe Avenue, and Hubin Avenue. A baseline sampling point was set every 200 meters along the green belt, and additional high-density sampling points were set in areas with abnormal plant growth. A total of 23 multi-profile soil samples were collected at different depths (0-20 cm, 20-40 cm, 40-60 cm, 60-80 cm and 80-100 cm). The study systematically determined six key soil parameters: pH, salinity, organic matter, available nitrogen, available phosphorus and available potassium using standardized analytical methods including pH meter (PB-10), oven-drying gravimetric method and externally heated dichromate oxidation method. Then the in situ dataset of soil nutrients in urban green belts of Dezhou City, China (2024) was obtained. The dataset includes: (1) the geographical locations and surface vegetation data of the sampling sites; (2) measured soil nutrient data from the greenbelt, including stratified values of six fertility indicators: pH, salinity, organic matter, available N, available P, and available K; (3) statistical characteristics of soil nutrient data; (4) mean membership values of different soil indicators across soil layers and roads; (5) soil fertility evaluation index across different layers and roads; (6) data used for calculation. The dataset is archived in .shp and .xlsx formats, and consists of 8 data files with data size of 191 KB (Compressed into one file with 160 KB).
