中国地震应急二级分区的初步研究

在已有地震应急宏观分区研究的基础上,首先讨论了进一步开展地震应急次级分区的意义及其分区方案的多样性;然后提取“政治经济强辐射中心、少数民族聚居区、贫困人口聚居区、侨乡、大型工业危险源”等5方面社会经济因素在不同县域内的10种主要组合类型作为区划指标,采取“自下而上归并”的区划途径,进行了中国地震应急二级分区研究。结果表明,在将我国大陆划分为8个地震应急一级大区的基础上,从社会经济角度又可大致划分出19个二级区;二级区的划分进一步揭示了不同地区开展地震应急工作时应注意的一些较具体的社会经济问题及其空间配置特点;两级分区的结合从“宏观概括”和“中观具体”两个层次示范了地震应急分区研究的基本内容。

The Preliminary Study on the Second-Level Zonation for Earthquake Emergency Response (EER) of China

Based on the study of macro-scale zonation for EER,this paper firstly discusses the significance and the diversity of it's sub-level zonation.Then using county as the basic analyzing unit,10 main combination types of five social-economic factors,including politics and economy center,minority habitat,depressed area,emigrant residence and hazard-deriving source of large-sized industry,are picked out as second-level zonation index.Finally through the bottomto-up merging approach,the paper performs the second-level zonation.The result shows that 19 second-level regions can be divided after the first-level regions obtained,the layout of it's second-level regions further exposes some more detailed social-economic problems and their spatial distribution pattern,to which attention in EER should be paid.The combination of these two-level divisions demonstrates the elementary contents of EER theory and practice from "macroscopic and general" level and "meso-scopic and specific" level respectively.
