2009-2010年中国森林土壤剖面调查数据

按照《森林土壤调查技术规程》，挖掘剖面，观察并记录剖面地表景观，海拔高度，经纬度，坡向，坡度，植被覆盖类型，剖面层次特征等,同时记录了剖面样点的大区地形，小区地形，母岩种类，母质种类，地面侵蚀情况，土地利用情况，以及植物种类。同时，还详尽描述了土壤各层次的干、湿状态下的土壤颜色，湿度，层次过渡状况，结构，紧实度，根量，硝酸盐反应，石砾含量，新生体，侵入体，pH以及剖面综合特征。In accordance with the Technical Regulations for Forest Soil Survey, soil profiles were excavated, and relevant information including the surface landscape, elevation, geographic coordinates (latitude and longitude), slope aspect, slope gradient, vegetation cover type and profile horizon characteristics was observed and recorded for each profile. Moreover, the macro-regional topography, local topography, parent rock type, parent material type, surface erosion status, land use status and plant species at the profile sampling sites were also documented. Additionally, detailed descriptions were provided for soil color, moisture content, horizon boundary characteristics, soil structure, compactness, root quantity, nitrate reaction, gravel content, soil neoformations, inclusions, pH value and comprehensive profile features of each soil horizon under both dry and wet conditions.
