浙江省250米土壤pH栅格图（1990年）

该图土壤pH属性含量来源于中国土种志，反映了二普时期浙江省pH含量的分布规律。可作为编制浙江省土壤资源图和肥力图的基础，也可为浙江省土壤利用改良区划、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。

The soil pH data included in this map are sourced from the *Soil Species Gazetteer of China*, reflecting the distribution pattern of soil pH values in Zhejiang Province during the Second National Soil Survey of China. This dataset can serve as the basis for compiling soil resource maps and soil fertility maps of Zhejiang Province, and provide a scientific basis for soil utilization and improvement zoning, agricultural regionalization, natural regionalization and other relevant regional planning works in Zhejiang Province. It can also be used as a reference for agricultural and forestry departments, scientific research institutions and educational institutions.
