地震活动空间分布不均匀性的多尺度分析

利用空间尺度显著性分析方法，本文讨论了中国大陆东、西部地区、台湾地区以及新西兰地区地震活动的空间分布特征.结果显示，地震活动具有多尺度空间成丛分布与随机分布特征.在不同空间带宽情况下，处于板块边缘的台湾、新西兰地区地震活动空间分布规律性较好，而中国大陆地区则规律性较弱.文中还讨论了窗宽的选择对人们认识地震活动空间分布特征的影响.

Multiscale exploration for asymmetrical features on spatical distribution of earthquakes

On the basis of space scale significance analysis method, the spacial distribution features of earthquakes in Eastern and Western mainland China, Taiwan region and New Zealand have been discussed. Results show that the distribution of events normally characterizes multiscale clustering and stochastic patterns. Within different bandwidths, results always show the distribution of events in Taiwan and New Zealand, where cover/close to boundaries of tectonic plates, more regularity than that in Eastern and Western mainland China. Also, the effects of bandwidth on features understanding of spacial distribution of events have been discussed in this paper.
