天津市郊区表层土壤理化性质样本数据（2016年）

根据天津市主要土壤类型并兼顾土地利用类型，采用网格布点法在天津市宝坻区、北辰区、东丽区、蓟州区、津南区、静海区、宁河区、滨海新区、武清区、西青区共布设330个样点，采集表层0-10cm土壤，涉及的土地利用类型有耕地、林地、园地、草地和其他用地，主要土壤类型包括潮土、褐土、滨海盐土、草甸沼泽土、潮褐土、砂姜黑土、湿潮土、石灰性褐土、盐化潮土与盐化沼泽土。在天津师范大学水资源与水环境重点实验室，采用行业标准测定方法和等效方法测定土壤主要物理、化学性质，为研究土壤因子对土壤风蚀起尘的影响提供基本数据。

According to the dominant soil types in Tianjin and taking land use types into account, a total of 330 sampling points were laid out via the grid sampling method across 10 districts and areas of Tianjin, including Baodi District, Beichen District, Dongli District, Jizhou District, Jinnan District, Jinghai District, Ninghe District, Binhai New Area, Wuqing District and Xiqing District. Topsoil at a depth of 0-10 cm was collected at these sampling points. The involved land use types cover cultivated land, forest land, garden plot, grassland and other lands, while the main soil types include aquic cambosols, cinnamon soils, coastal solonchaks, meadow bog soils, aquic cinnamon soils, shajiang black soils, hydragric aquic cambosols, calcic cinnamon soils, salinized aquic cambosols and salinized bog soils. The major physical and chemical properties of the soil samples were determined using industry-standard and equivalent methods at the Key Laboratory of Water Resources and Aquatic Environment, Tianjin Normal University. This dataset provides basic data for studying the impact of soil factors on soil wind erosion and dust emission.
