补充资料：水涝害
| 水涝害 waterlogging damage 由于降水过多，农田土壤过湿、淹水或洪水泛滥而造成的自然灾害。水涝害可分为3类：连阴雨或积雪融化，土壤水分长期处于饱和状态，作物根系因缺氧而生长滞缓，产量降低，称湿害或湆；雨水过于集中，排泄不畅，田间积水，为害根系，引起植物萎蔫、落花、落果、空壳瘪粒以至倒伏、霉烂，称涝害；大雨引起山洪暴发、河水泛滥，淹没农作物，危害林木，冲毁农田、畜舍和农业设施，称洪水害。降水过多、过于集中是发生水涝害的直接原因。地理、土壤和排水状况，可影响水涝害的程度。如汇水面积大的江河下游易受洪涝害；粘土和有不渗水层的土壤，雨水稍多时就生湿害；洼地排水困难常大面积受涝。不同作物和不同生育时期对土壤过湿和积水的适应能力不同，受害情况也不一样。中国近500年来水涝害频发时期和少发时期交替出现，有准周期特点。不同纬度带水涝害发生的频次不同，北纬25°～30°发生的频次较多。涝害最严重地区主要在黄淮平原和长江中下游，其次是东南沿海、松花江及辽河中下游。防涝抗涝的主要措施是：掌握规律, 加强预报，疏通河道、加固堤防，兴修水库、蓄洪防涝，开挖沟渠、形成排水体系，造林种草、防止水土流失，因地制宜安排农业生产。 |
