| 摘 要： | 利用1970—2008年六盘水市的日平均气温、降水资料以及小麦产量数据，分析了六盘水市小麦生长季的气候变化特征及气候因子对小麦产量的影响。结果表明。六盘水近39年小麦生长季气温呈上升趋势。降水呈下降趋势；小麦的相对气象产量变幅较大；2～4月的降水是小麦产量形成的关键因子；小麦减产的主要气象灾害是中等强度或重度倒春寒及冬春连旱。

| Abstract: | The characteristics of climatic variation in Liupanshui and it's effects on wheat yield were analyzed based on daily mean temperature data,precipitation and wheat yield from 1970 to 2008 in Liupanshui.The results showed that the temperature during wheat growing season increased obviously but precipitation decreased in recent 39 years.The relative meteorological yield of wheat changed significantly in recently 39 years.Precipitatiion from February to April was the key factor of wheat yield.The main disasters... |
