摘　　要：】本文讨论了大气边界层理论及其与病原菌远距离传输的关系。包括大气边界层的一般概念，大气边界层内的气流方向，病原菌分生孢子进入大气层的动力，分生孢子的远程输送与沉降。此外，还以小麦白粉病为例。This paper introduces the theory of atmospheric boundary layer (ABL) and describes its association with long distance inoculum transport, including the general concept of ABL, the airflow direction of ABL, the motive force of spore emitting into ABL and the motion and sedimentation of spores. The prospect of application of this theory in plant epidemiological research is analysed and verified with wheat powdery mildew as an axample.
