%X The characieristics of fog water and its effects on masson pine in Nanshan mountains, Chongqing were studied. The results of fog water analysis showed that it was sulfur acidic fog with an average pH value of 4.5(3.6-5.6). The major components of the fog water were SO2-4, Ca2+and NH4+.The total ionic concentration was 9.3 times of that of the rain water at the same season. There was a large amount of particiulate-matter in the fog water. The pH value of the fog water condensed on the needles of pine decreased to 3.0 or below,indicating possibilities of le aching of Ca2+, Mg2+ and NO3- ions from the needles and the effect on needle chlorophyll. The particulate matter in the fog water might affect the needle, photosynthesis by blocking up the stomas.
