摘要
分析了鹤壁市地质灾害时空分布特征及造成地质灾害的天气条件,采用5日滚动累加法,判定地质灾害降水类型,提出当日强降水型和前期强降水型与鹤壁市地质灾害的关系;集本地人工神经网络降水量预报和上级指导产品做诱发地质灾害的短期降水预报,并利用卫星云图、雷达、闪电定位仪等探测手段建立鹤壁市地质灾害预报预警系统。
This paper analyzes the space-time distribution characters of geological disaster and its weather conditions in Hebi, and in terms of 5-day-roll-accumulation method, we determine the patterns of precipitation, and propose the relationship between geological disaster and heavy precipitation patterns; based on the local artificial nerve network precipitation forecast and superior directive product shot-time precipitation forecast that induces geological disaster is developed. And by using satellite cloud pictures, radar and lightning direction finder, forecast and early warning system of geological disaster is established in Hebi.
