中国油茶潜在分布预测及适宜土壤条件评价试验数据集

油茶分布点的位置数据及土壤养分情况的原始数据来源于知网检索到的的2008-2018年油茶相关文献中的数据，对数据进行筛选、剔杂、插补与重分析。字段包括：油茶品种、区域、东经、北纬、采样时间、采样深度、采样地、样本量、土壤类型、母岩、土壤密度、有机质、酸碱度、全氮、全磷、全钾、速效N、速效P、速效K。The raw data regarding the locations of Camellia oleifera distribution points and soil nutrient status were sourced from relevant studies on Camellia oleifera published between 2008 and 2018, retrieved from the CNKI database. The raw data were subsequently processed via screening, outlier removal, imputation and re-analysis. The dataset includes the following fields: Camellia oleifera cultivar, region, east longitude, north latitude, sampling time, sampling depth, sampling site, sample size, soil type, parent rock, soil bulk density, organic matter content, pH value, total nitrogen, total phosphorus, total potassium, available nitrogen, available phosphorus, available potassium.
