CLASSIFICATION AND REFERENCE OF THE BLEACHED SOIL ON TERRACES OF MINGSHAN,WEST SICHUAN
摘要
Abstract
Intensely leached soil is a unique type of soil and has an important position in the soil classification system. For its classification, bleached soils on the second, third, fourth and fifth terraces of Mingshan County, West Sichuan where they are widely distributed, were investigated and sampled in field and analyzed in laboratory. Following the principle and methods of Chinese Soil Taxonomy (CST) , their diagnostic horizons were identified and their diagnostic characteristics, such as anthrostagic epipedon, hydragric horizon, albic horizon, anthrostagnic moisture regime, redoxic features, determined; and by means of sequential searching, they were sorted into Anthrosols in order, Stagnic Anthrosols in suborder, Hapli-Stagnic Anthrosols and Fe-accumulic-Stagnic Anthrosols in group, Albic Hapli-Stagnic Anthrosols, Albic Fe-accumulic-Stagnic Anthrosols, and Typic Fe-accumulic-Stagnic Anthrosols in subgroup, and according to the Genetic Soil Classification of China (GSCC) , they fell into the subgroup of Bleached Paddy Soil. Comparatively speaking, CST can more accurately discriminate soils, which favors standardized management of soils. However, CST still needs to be further perfected.关键词
