- Abstract:
- [Objective]Climate change has had an important impact on the natural environment and human activities, and it is important to clarify the frequency and intensity of extreme climate disasters in the context of global change to maintain the safety of people's lives and property. [Methods] According to the daily data of 102 meteorological stations in Qinlin-Daba Mountains from 1970 to 2017, linear regression, inverse distance weighting(IDW)and Z-index method transform were used to analyze the climate change characteristics of the Qinlin-Daba Mountains in the past 48 years. The responses of regional drought and flood disasters in the four highland areas of the great undulating high mountains in the western Qinling-Daba Mountains, the great undulating middle-high mountains in Qinling Mountains, the great undulating middle mountains in Daba Mountains, and the middle mountains and lower valleys of the Hanzhong in the west of Henan were examined, and the spatial difference of drought and flood disasters in the area was further analyzed. [Results] The temperature in Qinlin-Daba Mountains increased by 0.3℃/decade in the past 48 years, and the precipitation increased at a rate of 0.87 mm/decade. The climate of the whole area were warming and humidifying. In the past 48 years, the temperature in different terrains had been increasing, but the rates of increase were different. The growth rate of the great undulating middle mountains in the Daba Mountains was the largest(0.7℃/decade), and the growth rate of lower valleys of the Hanzhong in the west of Henan was the least(0.2℃/decade). In terms of the trend of the precipitation changes, the precipitation in the central and the great undulating middle mountains in Daba Mountainswas significantly higher than that in other topographic areas, with the highest change tendency(13.45 mm/decade), and change tendency in lower valleys of the Hanzhong in the west of Henan was 0.06 mm/decade. The inter-annual differences in the occurrence of droughts and floods in Qinlin-Daba Mountains were obvious, and there was an increasing trend from 1970 to 2017. The responses of four regional droughts and floods to climate change were different: the drought and flood disasters in the great undulating middle mountains in Daba Mountains compared were related to climate change. The response showed overall abundant precipitation, and the frequency and intensity of the disasters increased. The great undulating middle mountains in Daba Mountains and lower valleys of the Hanzhong in the west of Henan showed a general drought, and the frequency and intensity of the drought were significantly higher than the disaster. [Conclusion] From 1997 to 2017, the Qinlin-Daba Mountains area showed a warming and wetting phenomenon, and the frequency and intensity of extreme climate events showed an increasing trend. The conclusions of this study can provide a basis for the classification and grading of soil and water conservation planning in different regions.
