摘要:
南充是四川地质灾害隐患点分布较多的地区之一,探索雨量与地质灾害的关系,进行提前预警,显得尤为重要。利用2000—2017年南充228个加密自动站和大监站观测资料,结合地质灾情数据,使用基于衰减系数计算有效降雨量与降雨强度(I)-历时(D)关系阈值相结合的方法,对不同致灾降雨类型进行分型判断,开展不同时效雨量阈值研究。分析发现:大约有72.6%的地质灾害是主要由降雨因素诱发,其中主要由短期降水引发的占77.3%。短期和中长期降雨型地质灾害的易发区分别为西北部和偏南地区,而西北部地质脆弱山区和水库流域对短时强降雨最为敏感。
Abstract:
Nanchong is one of the areas with more geological hazards in Sichuan. So it is very important to find the relationship between rainfall and geological hazards in Nanchong to make early warning. Based on the observation data of 228 dense automatic stations and monitoring stations in Nanchong from 2000 to 2017, combined with the geological disaster data, we classified different types of disaster rainfall by a method of combining the calculated effective rainfall based on attenuation coefficient with rainfall intensity (I)-time (D) relation threshold, and studied threshold of rainfall in different duration. It is found that about 72.6% of geological disasters were mainly caused by rainfall, of which 77.3% were mainly caused by short-term rainfall. The geological hazards prone areas caused by short-term and long-term rainfall were mainly distributed in northwest and south of Nanchong, while the vulnerable mountain area and the reservoir basin in the northwest Nanchong were most sensitive to the effects of short-term heavy rainfall.
