| Abstract: | A comparative study on micromorphological features of purple soil, distributed in Hunan, Jiangxi, Zhejiang, Yunnan and Sichuan Provinces has been made based on the soil samples thin sections.Differed from other types of soils,the main micromorphological features of purple soils are skeletal micromorphology, sandy agglomeroplosmic fabric and detrital agglomeroplosmic fabric-the principal fabric patterns. Moreover,it has been suggested that the above-mentioned micromorphological features of purple soils can act as diagnostic characteristics in taxonomic classification of purple soils.Some other micromorphological features, such as mineral composition, morphology and quatity of skeleton grains, microzone eluviation of plasma and quality of micropores may be considered as the indices of purple soil fertility status and its degradation. |
