贵德县近50年气候变化及对冬小麦生产潜力的影响OA北大核心CSCDCSTPCD
Climatic Changes in the Past 50 Years in Guide County, Qinghai Province, and Their Influences on Potential Productivity of Winter Wheat
利用青海省贵德气象站1961—2010年逐日平均气温、逐月降水资料以及逐日日照时数资料,分析近50a气温、降水以及日照时数的变化。利用Tharnthwaite Memorial模型,以实际的蒸散量计算得到冬小麦的气候生产潜力。结果表明：（1）近50a来贵德气温呈明显的上升趋势,年降水量呈不明显的减少趋势,年日照时数呈明显减少趋势;（2）目前贵德冬小麦生产潜力开发程度偏低,现实生产力产量只有理论生产潜力的42.7%,气候生产潜力适宜开发程度为57.…查看全部>>
Change of the atmospheric temperatures, precipitation and light hours in the past 50 years in Guide County was analyzed based on the foundation data of Guide station from 1961 to 2010, including average daily temperature, monthly precipitation, and daily light hours. The potential productivity of winter wheat by using the model of Tharnthwaite Memorial and actual evaportranspiration data was calculated. The results were as followed, in the past 50 years, atm…查看全部>>
