【摘要】 使用气象产量指数（IDw）评价了气候条件对山西省粮食产量的影响，得到了一些有意义的结果，同时注意到山西省天然降雨并未得到充分利用及地处全国气候过渡带东沿等事实。分析认为山西省无人工灌溉条件的山区，只要充分利用天然降雨，辅以相应措施，就可自我调节与缓解干旱为害。山西省传统抗旱技术以提高土壤蓄水保墒能力为中心，适应了这一要求。因此，这一技术出现于山西省，特别是山西省东部，具有较好效果，并能长久流传下来有其气象学原因和深层次的科学内涵，至今仍具有现实意义。更多还原

【Abstract】 In this paper, the relationship between climatic condition and yield is evaluated using the weather yield index. It was considered in the analysis that the natural precipitation has not been. fully utilized and Shanxi located on the east extension of transitional climate zone. If the natural precipitation is fully utilized and same supplementary measures are adopted,the drought damage can be abated. This study shows that traditional technique of drought - resistant in Shanxi can satisfy the requirement. The emergence and permanent existence of the traditional technique and its efficiency can be attributed to meteorological factors. As a result, this paper suggests that such transitional technology should be summarized and popularized continuouslly.更多还原
