山东省黄河下游地区盐渍土地球化学特征

Geochemical Characteristics of Salted Soil in Lower Course Area of Yellow River in Shandong Province

摘要:

山东省黄河下游地区盐渍土受地质构造、地形地貌、水资源、气象等因素控制。盐渍土的形成与水体地球化学作用等密切相关。根据盐渍土地球化学元素分布规律、植物群落分布状况,将本区域划分成3个不同自然环境类型的地球化学分区和盐渍分区。为合理治理土壤盐渍化和系统规划农业布局提供信息。

Abstract:

Salted soil in lower reach of the Yellow River is controlled by geologic structure, landforms, water resource and climate. The form of salted soil has close relation with geochemical actions of water bodies. According to distribution law of geochemical elements and distribution condition of phytocoenosis, this area can be divided into 3 geochemical and saline divisions with different natural environment types, which can provide information for managing soil salinization and making plan of agricultural arran...
