【摘要】:本文对东汉时期自然灾害在时间上以及空间上的分布情况进行了探究,目的是要弄清楚自然灾害在东汉时期的时空分布特征,希望能够发现一些自然灾害在时空分布上的规律性的东西,并进而为当前的防灾减灾工作提供历史借鉴。 正文共分四章: 第一章回顾总结了东汉自然灾害的研究现状。 第二章主要是搜集自然灾害史料,并以表格的形式予以整理,随后对可疑或错误史料进行了分析批判。 第三章根据第二章的内容对东汉自然灾害的时间分布特征进行探讨。主要是讨论其时间上的发生状态,使用了列表法和统计法,目的是要通过图表更直观地向人们展示东汉时期自然灾害的发生情况,并通过统计把纷繁琐碎的灾害资料串连起来,进而对之分析和归纳,对其规律性给予探讨和总结。其中,年际分布一节中的年表是核心部分,灾害年际分布特征的探讨即以此为基础展开的,年际分布特征的探讨既有横向分析,也有纵向分析,同时还以各位皂帝在位时期为区间对灾害的发生情况进行了统计分析,其结果是清晰的:东汉自然灾害的集中高发期是在安帝时期,王朝后期较前期多发,王朝的政治、经济发展趋势与自然灾害的发展趋势基本上是一致的;年内分布一节中的图表则向我们清楚的展示了东汉时期自然灾害在一年当中各月间的分布状态呈现出很明显的规律性。 第四章对东汉自然灾害空间上的分布特征进行了探讨。从单灾种的地区分布展开,基本上弄清楚了东汉时期自然灾害空间分布情况:各种自然灾害基本都是发生在今河南、山东、河北、安徽、陕西、山西、江苏北部以及湖北北部,其大致范围在北纬30℃—40℃、东经110℃以东地区。上述地区正是当时人口密度大的地区,由此可见自然灾害主要是危害人口稠密、经济发达的地区。因此,人口稠密和经济重心地区应当是重点防灾地区。
[Abstract]:This paper probes into the distribution of natural disasters in time and space in the Eastern Han Dynasty in order to find out the space-time distribution characteristics of natural disasters in the Eastern Han Dynasty. It is hoped that we can find out the regularity of the distribution of natural disasters in time and space and provide historical reference for the present work of disaster prevention and mitigation. The text is divided into four chapters: The first chapter reviews and summarizes the research status of natural disasters in the Eastern Han Dynasty. The second chapter mainly collects the natural disaster historical data, and arranges in the form of the table, then carries on the analysis and the criticism to the suspicious or the wrong historical data. The third chapter discusses the time distribution characteristics of natural disasters in the Eastern Han Dynasty according to the content of the second chapter. The purpose is to show people more intuitively the occurrence of natural disasters in the Eastern Han Dynasty through the graph, and through statistics to connect the numerous and trivial disaster data, and then analyze and summarize them. In the section of interannual distribution, the chronology is the core part, and the discussion of the characteristics of interannual distribution of disasters is based on this, and the discussion of interannual distribution is based on the horizontal analysis. There is also longitudinal analysis, and at the same time, the occurrence of disasters is statistically analyzed in the period of emperors Zaodi. The result is clear: the concentrated natural disasters of the Eastern Han Dynasty is in the Andi period. The political and economic development trend of the dynasty is basically consistent with the development trend of natural disasters. The charts in the distribution section of the year clearly show that the distribution of natural disasters in the Eastern Han Dynasty during each month of the year shows a very clear regularity. Chapter 4th discusses the spatial distribution of natural disasters in the Eastern Han Dynasty. The spatial distribution of natural disasters in the Eastern Han Dynasty was basically made clear: all kinds of natural disasters basically occurred in Henan, Shandong, Hebei, Anhui, Shaanxi, Shanxi, northern Jiangsu and northern Hubei. Its general range is 30 鈩,
