该文分析了黄河大柳树灌区土壤类型形成条件与分布格局和主要土壤类型的基本特征,在此基础上结合发展灌溉农业对土壤条件的要求,提出土壤资源合理利用与发展灌溉农业的有关问题。
This paper first discusses the forming condition and dasic features of
soil types,as well as their distribution pattern, setting up a system for soil
classification in the studied region. Secondly, the authors analyze the qu-
antitative structure and suitabilities of every soil types. On the basis of
