By means of the advanced information technology， in combination with weather forecast and climate analysis，based the small and mediumscale network of automatic weather stations， a GISbased realtime weather information service system for natural rubber planting is established. The system， based on the physiological characteristics of rubber at the cutting and nocutting stages， can be applied to the supervision and management of rubber trees in Xishuangbanna according to the realtime weather conditions （precipitation， temperature）， by which inquiring， monitoring， and forecasting can be conducted in a timely manner， so to minimize the adverse effect of weather on rubber tree and to reduce production losses as much as possible.
