Transport of marine substance from sea to coastal farm land.

本研究的目的是分析海洋气溶胶从海洋到沿海农田的传输.测量海洋气溶胶的方法：当风从海洋吹到陆地时，气泡水的电导率增加，用激光颗粒计数器测量的海洋颗粒，当风从陆地吹到海洋时，电导率降低。用小型船用雷达测量了10米尺度的雨盒。有可能测量大型海洋气溶胶造成的海洋盐的损害与雷达.用叶绿素荧光法测定盐雾后作物叶片的光合活性。在盐雾后1、2小时内测定作物的活性。可以预测盐雾对作物叶片的危害程度.在加拉津沿海地区，来自海洋的干湿沉降量几乎相同。雪中海洋物质的含量在佐贺县的三濑地区最少。1995 ~ 2002年对东松浦半岛地下水水质进行了调查。硝态氮浓度较高，最高可达60 ppm以上。1995 ~ 2002年，地下水中硝酸盐浓度基本保持不变，而地下水中溴离子浓度则呈下降趋势。

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.
