This paper also shows the distribution of the fluorine in sediments of the area is mainly controlled by the chemical composition of the material from the surrounding islands, and the element seems to be incorporated by the hornblende at the most extent, thus the correlation between the element and the hornblende amount in the sediments can be expressed statistically as following: F=217+lnVh.

研究结果表明，测区沉积物中氟含量分布主要受周围岛屿风化基岩的化学成分制约；沉积物中主要含氟矿物：萤石/磷灰石、黄玉、黑云母等含量极低，氟在沉积物中赋存的矿物相主要与角闪石[AX_2Y_5Z_8O_(22)_2]有关。氟含量与碎屑矿物中角闪石的体积比间的关系式可大致表示为：氟含量=217+361nV_H；间隙水中的低氟主要由测区化学风化不发育及氟的钙盐沉积所致。

The result showed that the effect on soil fertility quality not notability; the effect on the flue-tobacco yield have notable different under different green manure, and wheat 、cabbage and cole higher than CK, horsebean is lowest. Planting green manure can ameliorated quality, and cole treatment was more harmony in chemic component, and than was cabbage.

本试验结果表明，在一年种植的基础上，种植绿肥对植烟土壤肥力影响有限；烟叶产量方面种植小麦、白菜、油菜好于对照，蚕豆最差；质量方面种植绿肥可以在一定程度上改善化学成分协调性，有提高烟叶品质趋势，其中以油菜处理的化学成分协调性更好，白菜次之，而蚕豆和小麦一般。
