南方红壤区土壤和植物调查数据(2014)

2014年5月19日-26日在浙江金华、江西鹰潭、湖南祁阳、广东鼎湖山路线进行了四省区酸性土壤和植物调查，旨在摸底我国东南典型酸性土壤区的土壤酸化现状。调查根据不同母质发育的红壤、同一地区相同母质不同土地利用方式（林地、茶园、果园、农田）下红壤、同一地区相同母质相同土地利用方式不同种植年限（不同pH）下红壤酸等选点，在浙江金华考察了12块样地，江西鹰潭15块样地，湖南祁阳18块样地，广东鼎湖山8块样地，共计采集了54个表层土壤样以及土壤剖面样，同时采集了215个植物样。分析了土壤理化指标和全部植物样品，数据集具体包括2014年南方红壤区土壤理化指标、植物养分数据和调查地的经纬度和植物种类，具体测定指标包含环境因子、植物种类、养分指标，磷分级，硝化能力和土壤理化因子数据

From May 19 to 26, 2014, a survey of acidic soils and associated plants was conducted across four provinces (Zhejiang, Jiangxi, Hunan, Guangdong), with field sites located in Jinhua, Yingtan, Qiyang and Dinghushan, aiming to characterize the current status of soil acidification in typical acidic soil regions of southeastern China. Sampling plots were selected based on three criteria: red soils developed from different parent materials; red soils under different land use types (woodland, tea plantation, orchard, cropland) with the same parent material in the same region; and red soils under the same parent material and land use type but with different planting years (and thus varying pH values) in the same region. A total of 12 sampling plots were investigated in Jinhua, Zhejiang, 15 in Yingtan, Jiangxi, 18 in Qiyang, Hunan, and 8 in Dinghushan, Guangdong. Collectively, 54 surface soil samples and soil profile samples were collected, as well as 215 plant samples. Soil physicochemical properties and all plant samples were subsequently analyzed. The dataset specifically includes soil physicochemical indices, plant nutrient data, the geographic coordinates of each survey site, and plant species information from the red soil region of southern China in 2014. Measured parameters cover environmental factors, plant species, nutrient indices, phosphorus fractionation, nitrification capacity, and soil physicochemical properties.
