National soil data of the Chinese Academy of Sciences

brief introduction ：

The spatial distribution data of soil types in China are based on the national soil survey office 1995 Prepared and published in 《1：100 Soil map of the people's Republic of China 》 Digital generation , Adopt the traditional “ Soil genetic classification ” System , The basic mapping unit is subclass , A total of 12 Soil class ,61 A soil ,227 A subclass . The number of soil attribute database records reached 2647 strip , Attribute data item 16 individual , It basically covers all types of soils and their main attribute characteristics in China .

FAO Global soil data

brief introduction

1960 At the 7th International Union Conference on soil science , Scientists suggest making a global soil map . So the international food and Agriculture Organization and UNESCO in 1961 In, it was decided to compile the scale as 1:500 World soil map of ten thousand . After more than 20 years of hard work , With the cooperation of numerous soil scientists all over the world FAO Soil Map, At present, this data is still the only soil resource overview soil map in the world .
