摘    要:新疆是我国积雪资源最丰富的区域之一,也是雪灾多发区之一,预测最大积雪深度,可以为雪灾的预警与防范提供参考和依据。本研究基于建立的雪灾灾损指数,确定了新疆特重雪灾区域;进一步聚焦特重雪灾区的8个县(市),包括阿勒泰市、福海县、青河县、塔城市、托里县、沙湾市、尼勒克县和伊宁县,分别建立县域RBF网络模型,预测2021—2050年年最大积雪深度,结果表明:该模型可用于新疆特重雪灾区最大积雪深度预测,但预测精度仍有待提升;塔城市、尼勒克县将于2025—2029年连续出现最大积雪深度偏高事件,2039年青河县将出现最大积雪深度的极大值,因此应关注可能发生雪灾的年份与县(市),积极做好雪灾的防御工作。

关 键 词:新疆  雪灾  最大积雪深度  RBF神经网络  预测

Prediction of maximum snow depth based on RBF network in severe snow disaster area, Xinjiang
Abstract:Xinjiang is one of the most abundant snow resources in China and also one of the frequent snow disaster areas. The prediction of the maximum snow depth can provide reference and basis data for the snow disaster warning and prevention. The study determined the area of Xinjiang heavy snow disaster based on the established snow disaster loss index. Further established the Radial Basis Function (RBF) network models to predict the annual maximum snow depth from 2021 to 2050 in Xinjiang extra severe snow disasters areas, including Altay City, Fuhai County, Qinghe County, Tacheng City, Toli County, Shawan City, Nilek County and Yining County. The results showed that the model can be used to predict the maximum snow depth in Xinjiang extra severe snow disasters areas, but the accuracy of prediction still needs to be improved; maximum snow depth continuous high event will happen in Tacheng City and Nilek County from 2025 to 2029. Qinghe County will have extreme value of maximum snow depth in 2039. Therefore, we should pay attention to the years and counties (cities) where snow disasters may occur and do our best to defend against snow disasters.
Keywords:Xinjiang  snow disaster  maximum snow depth  RBF neural network  prediction
