福建沿海地区生态农业地质地球化学单元划分

The Partition of Geological and Geochemical units for ecological agriculture in Coastal Region of Fujian Province

依据稻米、蔬菜样品重金属含量与柑桔品质的变化规律,选择地质背景、土壤pH和SiO23个指标,将福建省沿海地区土壤划分为16类31亚类76属级生态农业地质地球化学单元。生态农业地质地球化学环境对农产品的品质、质量具有重要的影响,单元划分对农业结构调整、土地利用区划具有指导意义。

In this paper, the soils in the Coastal Region of Fujian Province are divided into 16 classes, 31 sub-classes and 76 genus of ecologic agriculture of geological and geochemical units by the standard of geological background, pH value and silicon dioxide index of soil, which based on the variational rules of heavy metals content in the rice and vegetables and the quality of citrus fruits. The geological and geochemical environment of ecological agriculture： havegreat influenced on the quality and quantity of farm product. What＇s more, the partition of units has important instructional meaning on the agricultural restructuring and land-use regionalization.
