摘　　要：文章列举震前霜冻灾害与强震相对应的案例,指出这种对应关系的内在机制是:震前地壳内应力增强裂隙增多,使大量土壤微生物逸出地表;这些微生物可附着在农作物上,作为细菌冰核提高作物细胞间水分的过冷却点温度,导致霜冻灾害。Some cases that frost disasters before earthquakes correlate with strong earthquakes are listed.Inner mechanics of this kind correlation is that cracks increase duo to stronger stress in crust before earthquakes,which results in lots of microorganism in soil come out of ground surface.These microorganism may accrete on plant as bacterium ice nucleus which increases overcooling point temperature of water among plant cells,which leads to frost disaster.

关 键 词：霜冻害 细菌冰核 地壳破裂 土壤微生物
