澳大利亚 林火 生物多样性 巨大影响
2020/1/21
2019年7月以来，高温天气和干旱导致澳大利亚多地林火肆虐。截至目前，林火灾害已致28人死亡，2600多栋民居被毁，过火面积超过1000万公顷。持续数月的森林大火对当地生态系统和野生动物更是造成了巨大影响。被列入世界遗产名录的悉尼蓝山地区，占地103万公顷，这里有包括“活化石”植物瓦勒迈松在内的大量珍稀濒危物种。悉尼大学环境科学讲师阿伦·格林维尔日前表示，蓝山八成区域已经被林火烧毁。

日本 城市暴雨 内涝灾害 预测系统
2019/5/24
日本早稻田大学等机构最近为东京研发了城市暴雨内涝灾害预测系统，并争取在今年6月底之前开始试运行，希望能有助于大城市及时应对暴雨灾害。据早稻田大学20日发布的一份新闻公报，虽然日本现在也制作并发布城市“内涝受灾地图”和“洪水受灾地图”，但无法实时动态预测积水深度，且可信度方面存疑。

日本京都大学开发出泥石流灾害高精度预测技术
日本京都大学 泥石流灾害 高精度预测技术
2014/11/5
2014年8月，日本广岛市区受暴雨影响发生大型泥石流灾害，造成数十人遇难、数千幢房屋受损的严重后果。泥石流的精准预测成为防灾科研人员面临的重要课题。据《日刊工业新闻》报道，京都大学副教授小杉贤一朗的研究小组近期开发出通过评估泥石流发生前的降雨量数据预测泥石流发生可能性的数学模型。该模型利用降雨中真正渗入土壤的那部分“实效雨量”反映总降雨量（累计雨量）与降雨强度，而“实效雨量”通过“减半期”即降雨产...
