摘　　要：为了探讨湖北省克氏原螯虾(Procambarus clarkii)病害发生的气象成因,对历年湖北省主要克氏原螯虾养殖区的养殖期气象条件进行分析。结果表明,克氏原螯虾的产量增减与当地当年春季3-6月冷空气发生次数、低温持续日数、低温程度和气温变幅有一定的相关性。若当年冷空气活动频繁、低温持续日数多、低温程度重或者气温变幅越大,往往会导致当年的克氏原螯虾病害发生程度较重,并在当年的产量上得以表现。因此,对当年春季气象条件的监测和预测可以为克氏原螯虾养殖生产者提供决策服务,提醒生产者及时采取防治措施,以减少克氏原螯虾病害暴发的可能性或暴发程度。In order to investigate the meteorological cause of the occurrence of Procambarus clarkii＇s disease in Hubei province in recent years, the climatic conditions during the breeding stage of the main cultivation areas in Hubei were analyzed. The results showed that the production of P. clarkia had some correlation with the time of cold air＇s occurrence, the duration and degree of low temperature, and the amplitude of temperature in March to June in spring season. The more frequent the cold air activities occurred, the more duration days of low temperature continued, the lower the temperature level was, and the greater the magnitude of temperate fluctuated, then the more serious the disease would occur, and this could be reflected in the production of the year. Therefore, the monitoring and forecasting onto the meteorological conditions in spring could provide decision making services for the cultivators of P. clarkia, in order to remind to take timely prevention and control measures to reduce the probability or extent of disease occurrence.
