中国森林土壤调查、标准规范及数据库构建_华南典型森林土壤调查点基本情况表

2015-2018年在我国主要林区进行森林土壤调查，调查按照LY/T 2250-2014《森林土壤调查技术规程》操作，分区域选择区域代表性山脉按照土壤地带性分布特征，在20m*20m标准样地中挖掘标准剖面，记录地形、地貌、侵蚀状况、土地利用类型、植被组成及土壤剖面特征。数据包括调查日期、天气状况、剖面编号、具体地点、地理位置、海拔、地形、坡向、侵蚀类型、侵蚀强度、母岩种类、母质种类、土壤类型、森林类型等。

A forest soil survey was conducted in major forest regions of China between 2015 and 2018. The survey was carried out in strict accordance with LY/T 2250-2014 Technical Regulations for Forest Soil Survey. Representative mountain ranges were selected on a regional basis based on the zonal distribution characteristics of soils. Standard soil profiles were excavated in 20m×20m standard sample plots, and topography, landform, erosion status, land use type, vegetation composition and soil profile characteristics were recorded. The dataset includes survey date, weather conditions, profile number, specific site location, geographic coordinates, altitude, terrain, slope aspect, erosion type, erosion intensity, parent rock type, parent material type, soil type, forest type and other relevant information.
