项目摘要

The following results have been obtained through the approaches from air, water and terrestrial zones using various satellite data.1. Weather conditions on onshore areas in North-Eastern Asia: The sea features of the East China Sea, Yellow Sea and Bo-hai were investigated by the time series satellite observation. It revealed the change of water temperature, the freezing patterns of the sea water and the formation of the water front from early winter to late spring. The circumstances concerning the productivity on the Bo-hai area were specifically investigated in connection with weather conditions, existence of hinterlands, capacity of harbors and capability of transportations.2. Water pollution in the Bo-hai, Yellow Sea and the coastal areas in the West Japan: The observation using satellites was carried out first in the mouth parts of the Liao River, Tedong River and Amur River. With the aim of estimating the severity of water pollution, we have developed a new classification technique based on the Fussy theory which showed its validity and as well efficiency in application to the turbidity estimation on the Kanmon area. The turbidity estimation on the above-mentioned areas is under investigation using this technique.3. The correlation of the air pollution in the North-Eastern Asia and the acidic rain in Japan: Satellite data was used to identify the spots discharging pollutants, i.e., source materials of the acidic rain. The laboratory experiment was conducted to obtain the correlation with the satellite data. The study is partly successful but still under investigation.

通过使用各种卫星数据从空气、水和陆地区域的方法获得了以下结果。东北亚沿岸地区的天气状况：利用时间序列卫星观测资料研究了东海、黄海和渤海的海洋特征。它揭示了从初冬到晚春的水温变化、海水冻结模式和水锋的形成。二、对渤海地区的生产力状况，从气候条件、有无荒地、港口容量、运输能力等方面作了具体的调查。渤海、黄海和西日本沿岸地区的水污染：首先在辽河、特东河和阿穆尔河的河口进行了卫星观测。为了评估水污染的严重程度，我们开发了一种新的分类技术，基于模糊理论，这表明它的有效性和效率以及应用于关门地区的浊度估计。利用该技术对上述地区进行了浊度估算研究。东北亚空气污染与日本酸雨的相关性：利用卫星数据确定了排放污染物的地点，酸雨的物质来源。通过实验室试验，获得了与卫星数据的相关性。这项研究取得了部分成功，但仍在调查中。
