冀中南平原土壤氟地球化学特征及其控制因素

摘要

详细研究了冀中南平原土壤氟的地球化学特征,并探讨其控制因素.冀中南平原整体氟含量较高,且分布不均匀,具有明显分带性,分别出现4个高氟带和4个低氟带.氟在该区的分布明显受自然地理、地质因素和人为因素控制,且以自然地理、地质因素为主.在自然地理、地质因素中地貌起主导作用,而在人为因素中化肥为主导因素.%With central south Hebei plain as the study area, the authors studied geochemistry of fluorine in detail and explored its controlling factors. The results show that the fluorine content in central south Hebei plain is on the whole high, and the distribution is not uniform, having significant zoning characterized by four high and four low fluorine regions. The distribution of fluorine element in the area is significantly affected by physical geographic factors and artificial factors, with the natural geographic factors play the leading role. In the natural geographical factors, landscape is the main controlling factor, whereas in human factors, fertilizer seems to be the dominant factor.
