This paper analyzed the present situation and existing problems of ground information collection and sharing of weather modification operation, and sorted out the functional requirements of automatic collection system of weather modification operation parameters according to the performance characteristics of weather modification operation equipment and the technical requirements of operation information collection. This paper also designed and implemented the software and hardware system of ground operation information acquisition based on sensor technology, and completed the field test and business trial. Data analysis showed that the system ran stably, the precision of operational azimuth acquisition was ±5 °, elevation angle acquisition accuracy was ±3 °, the accuracy of quantity acquisition was 100%, the accuracy of data transmission was 100%, and the accuracy of all kinds of sensors met the needs of business assessment. The application and popularization of this system could effectively improve the time-effectiveness of ground information acquisition for weather modification operations, and help to fully grasp the dynamics of ground operations in the region,and improve the informationization and standardization management ability of weather modification operations.

on monthly air temperature and precipitation data at six stations from 1961 to 2004 around the Kumtage desert，the
variation characteristics of winter and summer air temperature，annual temperature range and summer precipitation around the region
were analyzed． The results show that the variation of air temperature and precipitation at six stations had well comparability and consistency
and presented increasing trend with obviously warm － wet change． Except for annual temperature range，the summer precipitation，
winter and summer air temperature all occurred climate jump． They were found by period analysis that the dominating period of
summer precipitation and air temperature before 1970 was about 12 years，and after 1970，it was 24 years，but the dominating period
of winter air temperature and annual temperature range was about 8 years．
