项目摘要

Scientists in Japan and China are planning the comprehensive cooperative study about water and carbon dioxide circulation over semiarid fields in China. To make sure this cooperative study, scientists of Okayama University and Kyoto University visited China from July 14 to 24, 1992, and inspected the Yucheng Experimental Station situated in the Shantung Providence. The Yucheng Station is located in the alluvial part of North China Plain where the natural disasters such as drought, water logging, flooding and soil salinization frequently occurred in the history. We discussed with chinese scientists about Key factors to be considered in our cooperative study We arrived agreement that following problems should be solved under the principle of equality and mutual benefit :Methodology for components of water balancePhysical process of water circulationWater balance of catchmentEvapotranspiration and water consumption by cropsDynamics of salts and alkalis within soil in relation to soil water movementResponse of crops to environmental factorsRemote sensing for interpretation of evapotranspiration, soil water content and crop growthIntroduction of new varieties and techniques for higher productivityThis cooperative study contributes to development of meteorology, plant physiology and hydrology of both countries as well as interchange of scientists between two countries.The cooperative program will be conducted by the institutes under the Chinese Academy of Sciences, Institute of Geography and other ministries in China, and the institutes under Japanese Ministry of Education, Culture and Science and other ministries in Japan represented by Okayama University. All of the related scientists sincerely want this cooperative program will be executed smoothly in near future.

日本和中国的科学家正在计划有关中国半干旱场上水和二氧化碳循环的全面合作研究。为了确保这项合作研究，冈山大学和京都大学的科学家于1992年7月14日至24日访问了中国，并检查了位于尚顿普罗维登斯的Yucheng实验站。 Yucheng站位于中国南部平原的冲积区，在历史上经常发生自然灾害，例如干旱，水记录，洪水和土壤盐水。 We discussed with chinese scientists about Key factors to be considered in our cooperative study We arrived agreement that following problems should be solved under the principle of equality and mutual benefit :Methodology for components of water balancePhysical process of water circulationWater balance of catchmentEvapotranspiration and water consumption by cropsDynamics of salts and alkalis within soil in relation to soil water movementResponse of crops to environmental factorsRemote sensing for interpretation of对更高生产力的新品种和技术的蒸发，土壤水含量和作物生长促进，这对两国的气象学，植物生理学和水文学以及两个国家之间的科学互换的发展有助于发展。冈马大学代表的日本教育，文化和科学以及其他部委。所有相关科学家都希望该合作计划将在不久的将来顺利执行。
