为优化配置省、市、县三级人工影响天气指挥作业资源，依据各级人工影响天气办公室的职责范围和任务特点，进行省、市、县三级人工影响天气作业指挥体制探讨。提出省级主要负责全省飞机人工增雨作业和全省地面人工影响天气预警、作业信息收集、监测等工作，市级主要负责属地作业点的直接指挥作业工作，县级主要进行作业监测工作。该体系体现市级指挥中心直接指挥作业点作业的模式特长，发挥省级飞机作业和地面作业预警的技术优势，减少县级人工影响天气办公室因人员少、技术力量薄弱等带来的作业水平不高的问题。解决三级资源共享和作业指令接收中的时间延迟等问题，提高作业时效和水平。

To optimize the allocation of the resources in a trilevel (provincemunicipalitycounty) operation command system for weather modification, a new operation command scheme is proposed according to the responsibility scope and the mission characteristics of weather modification offices at various levels. The provincial level is mainly responsible for plane precipitation enhancement operations, groundbased early warning for weather modification, operating information collection, and monitoring in the whole province. The municipal level is mainly responsible for the direct command of operational sites within the region. The main task at the county level is to carry out monitoring. The system embodies the peculiar advantage of the mode, i.e.， the direct commanding of operating sites by municipal centers, which gives full play to the technological advantages of the provincial plane operation and groundbased operational early warning and solves the problem which is caused by the less staff and weak technological force of countylevel weather modification offices. Also it realized the trilevel resource sharing, solved the problem of time delay while receiving operation instructions，and improved operational timeliness and performance.
