新疆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∶100万新疆土壤图经过数字化、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 generated by digitizing and conducting projection transformation on the 1:1,000,000 scale Xinjiang soil map derived from the Second National Soil Survey dataset, and subsequently updated with the latest land use data. Adopting the soil genetic classification standard, this map illustrates the major soil types in China and their spatial distribution patterns, and also briefly shows the distribution of cultivated soils and the utilization directions of all types of soils across the country. It can serve as a foundational reference for compiling national soil resource maps and soil fertility maps, provide scientific evidence for national soil utilization and improvement zoning, agricultural regionalization, natural regionalization and other relevant works, and is available for reference by agricultural and forestry authorities, research institutions and educational establishments.
