选取湘东7个起源花岗岩风化物的水稻土样点,按中国土壤系统分类指标体系,野外系统调查成土环境、描述土壤剖面形态,室内分析理化性质,研究其在中国土壤系统分类中的归属,评述土系的生产性能。结果表明,在水耕人为土亚纲下,划分出铁聚和潜育水耕人为土2个土类,普通铁聚水耕人为土和普通潜育水耕人为土2个亚类,进一步划分出6个土族和7个土系(车溪系、刘家场系、双家冲系、红阳系、柏树系、湾头系和福安系)。对于同一地区类似母土/母质发育的水耕人为土而言,基于系统分类的定量化指标(颗粒大小和质地层次)比基于发生分类的定性判定具有更强的划分能力。

To study the attribution of genetic classification of paddy soil in Chinese Soil Taxonomy and explore the production ability of soil series , 7 typical profiles of paddy soil developed from granite in eastern Hunan Province were dug.The soil-forming environment and soil profile morphological characteristics were examined , and physico-chemical properties were also analyzed .According to the Chinese soil taxonomy , under the suborder of stagnic an-throsol, 2 groups of fec-stagnic anthrosol and gen-stagnic anthrosol and 2 subgroups of typ-fec-stagnic anthrosol and typ-gen-stagnic anthrosol were ...
