项目摘要

The scientists of Okayama University in Japan and Institute of Geography in China have planned to make a joint effort on The Study of Water and Carbon Dioxide Circulation over Semi-Arid Fields in China. The results of this program contribute to development of micrometeorology and crop physiology of both countries.The present program is a preliminary stage of the comprehensive cooperative experiment that may be accepted in near future. In this year, three Japanese scientists visited the Institute of Geography in China from May 30 to June 14 in 1990, and inspected the experimental field of Yucheng Experimental Station situated in the Shatung Province. The field has an area of 5km x 5km. One scientist visited Okayama University from October 1 to 15 in 1990. He joined to the field experiment and workshop held in Okayama University. We discussed about research subjects. Following scientific problems will be solved by the cooperative experiment.(1) Energy budget over semi-arid field.(2) Transport mechanisms of water vapor over crop field.(3) Water distribution over crop field estimated by a remote sensing technique.(4) Observational study of evaporation and water balance in semi-arid fields.(5) Study on water requirement and techniques of water-saving irrigation for main crops in semi-arid fields.(6) Observational study of Km/Kh under advective conditions.(7) Transport mechanisms of carbon dioxide over crop field.(8) Observational study of carbon dioxide flux and carbon dioxide budget in semi-arid fields.(9) Numerical study of atmospheric boundary layer over semi-arid fields.

日本冈山大学的科学家和中国地理研究所计划在中国半干旱领域的水和二氧化碳循环进行研究。该计划的结果有助于两国的微量学位学和作物生理学的发展。目前的计划是在不久的将来可以接受的全面合作实验的初步阶段。今年，三位日本科学家于1990年5月30日至6月14日访问了中国地理研究所，并检查了位于莎士省的Yucheng实验站的实验领域。该场的面积为5公里x 5公里。一位科学家于1990年10月1日至15日访问了冈山大学。他参加了在冈山大学举行的实地实验和研讨会。我们讨论了研究主题。（1）半干旱场上的能源预算将解决科学问题。（2）（2）作物场上水蒸气的运输机制。（3）（3）通过遥感技术估计的作物场上的水分布。（（（ 4）半干旱场中蒸发和水平衡的观察性研究。（5）关于半干旱场中主要农作物的水需求和节水灌溉技术的研究。。（7）二氧化碳在作物场上的转运机制。（8）半干旱场中二氧化碳通量和二氧化碳预算的观察性研究。（9）半干旱场上大气边界层的数值研究。
