    闽西北泰宁县近50年农业气候资源及主要气象灾害变化特征分析

    Analysis of Agro- Climate resources Changes and the main Meteorological disasters

    • 摘要: 利用泰宁县1961~2010年的日照、气温及逐年无霜期、降水量等气象资料,分析作物生长期内的光资源、热量资源、水分条件及常见农业气象灾害的变化特征及气候趋势。结果表明:泰宁县作物生长季内日照时数呈两头高、中间低的形势,光照条件能满足喜温作物生长需求;热量条件呈增加趋势,90年代后期气温显著升高, 气温日较差呈下降趋势,初霜延后、终霜提前,无霜期延长,活动积温增加;水分条件波动较大,呈双峰型,80年代降水达最低值,为明显的干冷年份,70年代为冷湿,90年代后期多为温暖多雨年份1;低温冷害等农业气象灾害有减少的趋势,但洪涝、干旱、冰雹等灾害趋于频繁而严重。

       

      Abstract: Based on themeteorologicaldata of sunshine,temperature,precipitation,annual frost-free period in Taining from 1961 to 2010, the changed characters and clmiate trends of common agriculture meteorological disaster, such as the light resources, the thermal resources, themoisture condition were analyzed by climate statistical method. The results showed that the sunshine Was two high, middle low in the vegetal period of crops in Taining, but the illumination conditions could meet the growth requirements of thermophilic crops; The thermal condition increasing trend, The late 1990s, the temperature obviously elevated, the first frost postponed, the last frost advanced, frost-free period prolonged, the active accumulated temperature increased; Themoisture condition was fluctuation and bimodal type, In 1980s, the precipitation values reached the lowest, the dry and cold tendency was obviously; cold and humid periods in1970s; The late 1990s, mostly warm and humid; Agriculture meteorological disasters, such as cold damage the reduced tendency, but the flooding, hailhad and droughtdisaster tended to be fre-quentand serious.
