摘要/Abstract

摘要： 运用基于 PP回归理论的数值型地震综合预报软件系统, 对新疆天山地区进行了 PP回归建模研究。通过回顾性 PP回归动态建模预测检验,对其预报效能进行了评价。结果认为,该模型作为时序性数值预报模型具有较好的中短期预报效能。尤其对地震样本量大、震级分布完备的地区,其预报效能更好。

Abstract: In this paper, the PPR prediction model was established and studied for the Tianshan area in Xinjiang by using the comprehensive forecasting software system of projection pursuit regression. Setting up dynamic PPR prediction model and review of prediction efficiency show that the comprehensive forecasting efficiency in the medium-and short-term earthquake prediction, especially in those areas where have enough earthquake data sample and moderate and strong earthquake cases, such as Kepin and Wuqia areas.

Key words: PPR Model, Comprehensive forecasting, Efficiency evaluation
