【摘要】 本文利用１９４９—１９９４年的粮食产量、气象和水文资料，在分析了浙江省粮食单产和粮食播种面积对总产量年际变化的影响以及技术水平因素、社会因素、气象因素分别对粮食单产年际变化的影响基础上，从减轻气象灾害和提高气候资源利用效率的角度探讨了浙江省的粮食生产，并提出了若干相应的措施。更多还原

【Abstract】 Based on meteorological, hydrological and grain output data in Zhejiang during 1949-1994, the mean relative effect of per unit area grain yield and grain sowing area on the interannual variation of grain total output are analysed. The influence of technological, social and meteorological factors on the interannual variations of per unit area grain yield are also discussed. In light of the above mentioned discussions as well as in view of the meteorological disaster mitigation and improvement of climatic resources utilization efficiency, grain production in Zhejiang was studied and corresponding measures were raised.更多还原
