摘要/Abstract

摘要： 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。

Abstract: 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 physicochemical properties were also analyzed. According to the Chinese soil taxonomy, under the suborder of stagnic anthrosol, 2 groups of fec-stagnic anthrosol and gen-stagnic anthrosol and 2 subgroups of typ-fec-stagnic anthrosol and typ-gen-stagnic anthrosol were identified. Six soil families and 7 soil series (Chexi series, Liujiachang series, Shuangjiachong serirs, Hongyang series, Baishu series, Wantou series and Fu’an series) were established. This study implied that quantitative indicators (particle size and texture profile) in Chinese Soil Taxonomy were more useful for soil basal classification than descriptive classification in genetic classification system.

Key words: anthrosol, diagnostic horizon, diagnostic characteristics, Chinese soil taxonomy, basal classification, agricultural production utilization
