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对中国半干旱地区的水和二氧化碳循环进行综合合作研究。为落实此项合作研究，冈山大学和京都大学的科学家于1992年7月14日至24日访华，考察了位于山东省的禹城实验站。雨城站地处华北平原冲积区，历史上干旱、涝渍、洪涝、土壤盐碱化等自然灾害频发。我们与中国科学家就合作研究中需要考虑的关键因素进行了讨论，一致同意在平等互利的原则下解决以下问题：水平衡各组成部分的方法论水循环的物理过程流域的水平衡蒸发蒸腾和用水量作物土壤盐碱动态与土壤水分运动的关系作物对环境因素的响应遥感解释蒸散量、土壤含水量和作物生长引入新品种和技术以提高生产力该合作社该研究为两国气象学、植物生理学和水文学的发展以及两国科学家的交流做出了贡献。该合作项目将由中国科学院、地理研究所等国内部委单位开展，以冈山大学为代表的日本文部科学省等日本各省的机构。所有相关科学家都衷心祝愿这一合作项目能够在不久的将来顺利实施。
