| 摘 要： | 从作物水分供需出发,构建湖南省晚稻干旱指数模型,通过典型年份干旱指数与相应的旱情资料对比分析,确定了湖南晚稻干旱等级指标,并利用该模型分析湖南不同区域在晚稻各个生育阶段的干旱情况。就生长阶段而言,快速生长期、生长中期、成熟期可能出现极旱几率明显高于生长初期,一般在40%以上;从地区分布看,湘中、湘北重旱出现几率明显高于湘西和湘南。评估结果可为减轻晚稻干旱危害提供参考。 |

| Abstract: | The late rice drought index is constructed from the aspect of crop moisture demands.The drought level index of late rice in Hunan is brought forward through analyzing contradistinctively the drought index and drought data of the typical year.The validation with the drought data of late rice in growing season shows that droughts can be reflected by the late rice drought index and drought level index. The results show:as for growing seasons,the probabilityes of extreme drought in the fast growing,mid-growing,... |
