水库作为重要的防洪工程措施之一,在保证国民经济持续增长、维持社会稳定及缓解水资源供需矛盾等方面发挥了重要的作用,科学合理的水库防洪调度更能有效地促进其作用的发挥.针对目前水库防洪调度中存在的对历史洪水调度数据信息利用不足的问题,提出了采用随机森林(RF)回归算法制定水库防洪调度方案的新方法.首先,对历史洪水数据进行优化调度生成洪水优化调度数据集,由RF回归算法确定影响水库泄流量的主要影响因素;然后,将训练样本洪水过程逐时段的主要影响因素和泄流量输入RF回归算法生成泄流量回归树;最后,由回归树拟定验证样本洪水过程的泄流量.山东省田庄水库的实例论证了本方法的可操作性和合理性.

明确热浪特征及其对植被的影响对于工农业的发展和生态环境的维护至关重要.基于中国712个气象站点的日平均气温资料和归一化植被指数(NDVI)数据,以超热因子为指标定义热浪事件,并选择热浪次数、最长持续时间、频次和强度4个指数分析1961-2017年中国地区8个子区域热浪事件的时空变化特征,最后采用Spearman秩相关分析法探究热浪事件对植被的影响.结果表明,4个热浪指数呈显著增加的趋势,且在20世纪90年代和21世纪初发生突变.热浪次数、最长持续时间、频次在中国青藏、西部和东部地区的多年均值和变化趋势较大
