Climate Change Challenges China's Soil and Water Conservation
Recently, a researcher from the Institute of Soil and Water Conservation, Chinese Academy of Sciences, accepted the telephone interview with David Cyranoski, a correspondent for the Asia-Pacific region of Nature, about the cause of the catastrophe caused by the Zhouqu debris flow in Gansu.
In the interview, Deng Xiping introduced David Cyranoski to the characteristics of the occurrence of the Zhouqu debris flow in Gansu, the main causes and the degree of disaster based on the research results and practices of the Institute of Soil and Water Conservation in the field of soil erosion and soil and water conservation, combined with relevant information and reports. , Explained the intensity and distribution of soil erosion disasters in China. Regarding the causes of land degradation and debris flow, Deng Xiping believes that unreasonable felling and farming is one of the main reasons, which is easy to cause water erosion and wind erosion. The extreme climate increase caused by global warming has exacerbated this situation, among which The main reason for the huge debris flow is due to heavy rainfall in the short term. The extreme climate not only severely threatens southeastern China, it is even more severe for the arid regions in the west.
In explaining prevention measures, Deng Xiping believes that vegetation construction and restoration should be strengthened, and the monitoring and forecasting level of soil erosion should be increased to reduce and mitigate disaster losses and hazards. Under the current conditions, although it is also susceptible to extreme climates, and the developed coastal regions of China basically meet the above conditions, the poorer mountain areas still face the threat of serious soil erosion and other erosion.
When talking about the future development of the situation, Deng Xiping believes that as the country gradually strengthens and attaches great importance to vegetation construction and global climate change response measures, the situation will gradually improve, but it still needs the practical action of local governments.
