Transport of marine substance from sea to coastal farm land.

这项研究的目的是分析海洋气溶胶从海洋到沿海农田的输送1。测量海洋气溶胶的方法：当风从海洋吹向陆地时，起泡水的电导率增加，而用激光颗粒计数器测量的海洋颗粒，当风从陆地吹向海洋时，电导率下降。用小型船用雷达测量了10m尺度的雨区。用雷达测量对海洋盐类造成损害的大型海洋气溶胶是可能的。通过叶片喷盐后的叶绿素荧光测定，对作物的光合作用活性进行了评价。盐雾处理后仅在1~2小时内测定作物活性。可以预测从海洋到农作物叶片的盐雾对作物的损害程度。在Karatsu沿海地区，来自海洋的干湿沉降量几乎相同。佐贺县三泽地区的雪中海洋物质含量最少。对1995-2002年东松浦半岛地下水水质进行了调查。硝酸盐浓度较高，最高浓度大于60ppm。1995~2002年地下水中硝酸盐浓度基本保持不变，而地下水中溴浓度下降。

The purpose of this study is to analyze the transport of marine aerosols from sea to coastal farm land.1. The method of measuring marine aerosols: Electrical conductivity of bubbling water increased when wind blew from the sea to the land and marine particle, measured With a laser particle counter, decreased when wind blew from the, land to the sea. The rain cell of 10m -scale were measured with a small marine radar. There is a possibility of measuring large marine aerosols caused to the damage of marine salts with the radar.2. The photosynthetic activity of crop were estimated with chlorophyll fluorescence measurement after salt spray to leaf. The activity of crop were measured within only 1, 2 hour later after salt spray. It is possible to predict an extent of crop damage from salt spray from sea to crop leaf.3. In Karatsu coastal area, amounts of wet and dry deposition from the sea were almost same. The amount of marine substance in snow is smallest on Mitsuse area in Saga prefecture. The water quality of groundwater in Higashimatsuura peninsula was investigated from 1995 to 2002. The nitrate concentration was high and maximum concentration was higher than 60ppm. The nitrate concentration of groundwater was nearly constant from 1995 to 2002 and the bromide concentration of groundwater decreased.
