商洛地区旱涝灾害特征及其对气候变化的响应
Characteristics of Drought and Flood Disasters and Their Responses to Climate Change in Shangluo
摘要
Abstract
Researches on characteristics of regional drought and flood disasters are essential for effectively addressing the challenges posed by climate changes and mitigating disaster-related losses.In this paper,Shangluo City,Shaanxi Province was taken as a research subject,to discuss and analyze the drought and flood disaster chain and its relationship with climate changes over the past 60 years from 1959 to 2018 by utilizing classical statistical methods such as precipitation anomaly percentage and cumulative distance equality.The findings showed that:① From 1959 to 2018,there were drought or flood disasters in 28 years,with a probability of occurrence reaching 46.7％.②On average,either a drought or a flood occurred every two years in Shangluo,predominantly droughts occurred before 1980,while floods became more prevalent thereafter.③From 1959 to 2018,seasonal variations in drought and flood disasters were pronounced in Shangluo;waterlogging was most severe during summer,whereas droughts primarily affected spring,summer,and autumn with notable instances of prolonged multi-seasonal droughts.④There was a significant correlation between the occurrence of droughts and floods in Shangluo and regional climate changes.This research and analysis provides critical theoretical support for effective responses to climate change as well as scientific strategies for disaster prevention and mitigation in Shangluo.关键词
