摘  要：
为构建地形景观与水耕人为土土类及相关诊断层、诊断特性的关系,笔者以浙江省为研究案例,观察了254个水耕人为土的剖面特征。结果表明,铁聚水耕人为土出现的典型地貌有河谷平原、水网平原高地、洪积扇、丘陵坡岗地、滨海平原与水网平原的交接区域;潜育水耕人为土出现的典型地貌有水网平原的洼地、洋心田、河谷平原与丘陵过渡区和山垄;铁渗水耕人为土出现的典型地貌丘陵缓坡、河漫滩高地。铁聚层的层位和厚度在空间上较为稳定,而潜育特征和铁渗层的深度和厚度在空间上可有较大的变化。研究认为,地形条件是影响水耕人为土土类分异的主要因素,对水耕人为土中铁聚层、铁渗层和潜育特征的形成起着决定性的作用。

摘  要：
To construct the relationships between the landscapes and the soil types, related diagnostic horizons and diagnostic characteristics of stagnic Anthrosols, we investigated 254 soil profiles of the stagnic Anthrosols in Zhejiang. The results showed that: the typical landforms of Fe-accumuli-stagnic Anthrosols were river valley plain, highland of the river network plain, alluvial fan, hilly slope land, and the junction area of the coastal plain and the river network plain, those of the gleyi stagnic Anthrosols were depression of the river network plain, the center of the land surrounded by lake, transition area of river valley plain and hilly, and mountain ridge, and those of the Fe-leachi-stagnic Anthrosols were slope hilly and highland of flood plain.Depth and thickness of Fe-accumulated horizon in soils were relatively stable in space, while those of gleyi feature and Fe-leached horizon could change greatly in space. It is thought that the topographic conditions are the main factors which affect the differentiation of soil types of stagnic Anthrosols, and play decisive role in the formation of the Fe-accumulated horizon, Fe-leached horizon, and gleyic features of stagnic Anthrosols.
