Abstract:

The Yellow River Basin is an important part of ecological security strategy in China, and it is a sensitive area of climate change and a vulnerable area of ecological environment. This paper mainly analyzes and reviews the latest research progress on the characteristics, impacts, causes and countermeasures of climate change in the Yellow River Basin: (1) In recent 60 years, the temperature shows an upward trend, with an average warming rate of 0.30 ℃ per decade, and the trend of temperature rise is the most significant in winter and the smallest in summer. The precipitation in the upstream increased, while that in the middle-stream and lower-stream decreased significantly. (2) In recent years, under the joint influence of climate change and human activities, a series of problems have appeared in the Yellow River Basin, such as the reduction of runoff, the degradation of glaciers and frozen soil, the improvement of vegetation coverage, the increase of soil erosion in the ecological fragile areas of upstream and sand-producing areas of the middle-stream. The impact of climatic change on the crops is not only of advantageous aspects but also of disadvantageous, and the pets and diseases increase. The climate warming and the increase of extreme events have brought great challenges to the safe preservation of cultural heritage. (3) The evolution process of climate system in the Yellow River Basin is not only affected by its own internal power and heat, but also by external forcing factors such as atmospheric circulation, sea surface temperature and Qinghai Tibet Plateau. The change of atmospheric composition and land use/cover caused by human activities is an important factor affecting the local climate. (4) In the future, the temperature will still show an upward trend, the precipitation fluctuation will increase, and extreme weather events will occur more frequently in the Yellow River Basin. It is necessary and urgent to take adaptive measures to deal with climate change. These measures mainly include strengthening the scientific research on the impact of climate change and extreme events, improving the ability of forecasting and early warning of extreme weather events, establishing a disaster forecasting and early warning system integrating meteorology, hydrology, ecology, numerical prediction, prevention and control, strengthening the management, allocation and effective utilization of water resources, strengthening the protection of ecological environment, formulating scientific and reasonable agricultural development strategy, and promoting the high-quality development of the Yellow River Basin.
