以国际土壤系统分类的基层单元的划分原理和方法 ,研究建立了成都平原的土系。本文介绍了其中的长丘系、水口村系和界牌系等三个典型土系 ,并分别划分了其所属土族。通过研究土系的生态环境特征和土壤的生产性能 ,使土系划分在农业生产和区域生态环境建设上更有实用性。同时在土族划分上采用土壤微形态技术 ,使其划分依据更科学。本文的研究结果对土壤基层分类有一定的指导意义。

Using the taxonomy principles and methods of the basic units of World Soil Taxonomy, soil series in Chengdu Plain were divided. In this paper, three typical soil series such as Changqiu Series、Shuikoucun Series and Jiepai Series were introduced, furthermore of which the soil family were classified separately. Through the research of ecoenvironmental characters of soil series and soil production properties, it is more practical of soil series classification to agricultural production and regional eco-environment construction. Moreover based on soil micro-morphology technology, soil families were classified more scientifically. The results are significant to the division of basic units in soil taxonomic classification.
