The taxonomic classification,production properties and eco-environmental characters of typical soil series in Chengdu Plain

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 eco-environmental 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.
