调查采样分析了福建和浙江两省92个典型水耕人为土剖面,探讨了两省水耕人为土的优势类型及其分布规律。结果表明,铁聚水耕人为土和简育水耕人为土是主要类型,潜育水耕人为土和铁渗水耕人为土分布相对较少。调查共检出9个水耕人为土亚类,主要属于“普通”、“铁聚”、“漂白”和“底潜”类别的亚类。潜育水耕人为土主要分布在山垅、水网平原和河谷平原;铁渗水耕人为土集中分布在河谷平原和丘陵山地;铁聚水耕人为土主要分布在河谷平原和丘陵山地;简育水耕人为土在丘陵山地分布较多,在水网平原、滨海平原和河谷平原也均有分布。各类水耕人为土的“漂白”亚类则主要分布在丘陵坡地或河谷与丘陵的过渡区域。
A total of 92 typical hydroponic man-made soil sections in Fujian and Zhejiang provinces were sampled and analyzed. The dominant types and their distribution of hydroponic man-made soil in the two provinces were discussed. The results showed that anthropogenic iron and hydroponic artificial soil were the main types, and the distribution of artificial hydroponic man-made soil and iron seepage water was relatively less. A total of nine hydroponics man-made soil sub-categories were identified, mainly belonging to the sub-categories of “Common”, “Iron Poly”, “Bleach” and “Submarine” categories. The artificial hydroponic man-made soil is mainly distributed in the ridge, the water network plain and the valley plain; iron seepage water tillage is concentrated in the valley plain and hilly mountains; iron polyhydrophobic artificial soil is mainly distributed in the valley plains and hilly mountains; Man-made soil in the hills and mountains are more distributed in the water network plains, coastal plains and valley plains are also distributed. Various types of hydroponic artificial soil “bleaching ” subclasses are mainly distributed in the hilly slopes or valleys and hills of the transition area.
