Effects of climate change on the occurrence of crop diseases in China
基于全国农区527个气象站点1961-2010年逐日气象资料、逐年农作物病害发生面积以及产量资料,从气温、降水、日照等角度,采用相关分析方法,研究了气候变化背景下各气象要素变化对中国农作物病害发生的影响.结果表明:近50年来,气候变化导致的各气象因子变化总体有利于病害发生,年平均温度以0.27℃·10a-1的速率升高,其每升高1℃,可导致病害发生面积增加6094.4万hm2次；年平均降雨强度以0.24 mm·d-1· 10a-1的速度增加,其每增…查看全部>>
Based on the 1961-2010 daily observation data from 527 meteorological stations and the annual data of the crop diseases occurrence area and crop yield in farming areas of China, this paper studied the effects of various meteorological elements (air temperature, precipitation, and sunshine hour) on the occurrence and development of crop diseases in China under climate change. As a whole, the variation of the meteorological elements induced by climate change i…查看全部>>
