| 摘 要： | 我国单站旱涝等级划分尚未形成统一的评价指标体系,往往导致同一旱涝状况下旱涝等级评价结果存在差异.尝试将集对分析法应用于陕西省单站旱涝等级划分,提出了一种划分旱涝等级的新思路.结果表明,方法能综合运用各旱涝指数,不仅可以消除Z指数、标准化降水指数、降水距平百分率等降水指数考虑因素单一带来的不利影响,也能削弱相对湿润度指数、K指标等由于作物种类、气温条件等的影响而引起的评估偏差,较之传统的单一指标评价法更为客观合理.

| Abstract: | No uniform assessment indicator system exists in the grade classification of single station drought and water-logging,which can result in different classification results using different assessment methods for the same drought or water-logging condition.Set pair analysis(SPA) is proposed to classify the single station drought and water-logging in Shanxi province in this study.Results show that this method not only can avoid the adverse effects caused by the single parameter assessment method considering the... |
