陕西省1:100万土壤类型图（2018年）

本数字化土壤类型图是以全国第二次土壤普查资料1∶100万陕西省土壤图经过数字化、投影变换获得，并结合最新的土地利用数据进行了更新。该图采用土壤发生分类标准，反映了我国主要类型土壤及其分布规律，并概略地表示耕地土壤分布情况和全国各类土壤的利用方向。可作为编制全国土壤资源图和肥力图的基础，也可为全国土壤利用改良区划、农业区划、自然区划等提供科学依据，可供农林部门及科研、教学单位参考。This digital soil type map was derived from the 1:1,000,000 scale Shaanxi soil map compiled based on data from the Second National Soil Survey via digitization and projection transformation, and subsequently updated with the latest land use data. Adopting the genetic soil classification standard, this map illustrates the major soil types in China and their spatial distribution patterns, while briefly presenting the distribution of cultivated soils and the intended utilization directions of all soil types nationwide. It can serve as a foundational resource for compiling national soil resource maps and soil fertility maps, provide scientific support for national soil utilization and improvement zoning, agricultural regionalization, natural regionalization and related planning work, and is available for reference by agricultural and forestry authorities, scientific research institutions and educational units.
