摘要
对河北省抚宁、卢龙低山丘陵区土壤中作物营养元素的有效量与水系沉积物含量（全量）间的相关性研究表明：多数营养元素存在有显著的正相关关系。以区域水系沉积物元素地球化学资料为基础，可以近似定量地评价作物营养元素的丰缺状况。
Studies on some nutritive elements at Funing-lulong area showed that there were evident plus-correlations between their available values in soils and the concentrations in stream sediments. The supply level of these nutritive elements was evaluated by using the stream sediment geochemical data.
