中国1公里栅格土壤发生分类类型图（1990年）

本数字化土壤类型图是以“中华人民共和国1：100万土壤类型图”为蓝本，由中国科学院南京土壤研究所潘贤章课题组数字化。该1：100万土壤类型原图于1978年由中国科学院南京土壤研究所编图组编制，地图出版社正式出版发行。该图反映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 digitized by the research group led by Pan Xianzhang from the Institute of Soil Science, Nanjing, Chinese Academy of Sciences, based on the original "1:1,000,000 Soil Type Map of the People's Republic of China". The original 1:1,000,000 soil type map was compiled by the Mapping Group of the Institute of Soil Science, Nanjing, Chinese Academy of Sciences in 1978 and officially published by the Cartographic Publishing House. This map depicts the major soil types in China and their distribution patterns, and briefly illustrates the distribution of arable soils and the utilization directions of various soil types across the country. It can serve as a basis for compiling national soil resource maps and soil fertility maps, and also provide scientific evidence for national soil utilization and improvement zoning, agricultural zoning, natural zoning and other relevant works. It can also be used as a reference for agricultural and forestry departments, scientific research institutions and educational institutions.
