第十三届国际灌溉排水大会将于1987年在摩洛哥的拉巴特举行。最近,中国灌溉排水国家委员会收到国际灌排委员会中心秘书处来信,希望各国广泛宣传下一届大会的任务和议题,及早组织动员本国专家撰写论文,参加国际交流活动。现根据我处所得材料,将大会的任务和议题综合介绍如下。 The 13th International Conference on Irrigation and Drainage will be held in Rabat, Morocco, in 1987. Recently, the China National Committee for Irrigation and Drainage received a letter from the secretariat of the International Commission on Irrigation and Drainage. I hope that countries will widely publicize the tasks and issues of the next session of the General Assembly, and organize and mobilize national experts to write papers and participate in international exchange activities. Based on the materials available to me, the tasks and issues of the conference are summarized below.
