Soil Series Classification Approach——A Case Study in Xinyi, Jiangsu Province
摘要
Abstract
Soil series, the lower category unit of soil taxonomy, its classification should go through several indispensable processes, such as field investigations, establishment of control sections and characteristic:horizons, and choice of appropriate differentiation characteristics as category indexes. This paper selected 10 soil profiles in different landscape units of sample area, then discussed soil diagnostic horizons, diagnostic characteristics and the positions of the soils in Chinese Soil Taxonomy according to Chinese Soil Taxonomy. And based on the understanding about soil series, this paper proposed the principles, basis and the specific method about soil series classification, established the characteristic horizons of the sample area, the soils were divided into 10 soil series.and according to three indicators: 1) the type, arrangement, thickness of characteristic horizons,2) soil texture and 3) the content of organic matter.关键词
