摘要
通过分析、探讨清代陕西县治城市水灾发生的特征、机理及其与地区性水灾的关系,我们发现,城市水灾与地区性水灾关联度不高,江河暴涨暴落是城市水灾的主要致灾因子。水灾高发城市大多与城市所处的微地形地貌环境有关,62%的城市水灾发生在仅占总数17%的县城,突发性、局部性是清代陕西县治城市水灾的显著特征。人类因素在城市水灾发生、发展过程中,具有广泛性、隐蔽性和严重性,区域人类生产生活活动以及应对水灾的方略与措施,决定了城市水灾发生的频次与程度。充分认识和把握人类因素在城市水灾中的作用与影响,是我们从根本上认识城市水灾发生机理不可或缺的重要方面。
Analysis and discussion on the characteristics and the mechanism of urban floods made clear its low relationship with regional flood in Shaanxi province in the Qing dynasty.Sudden rise and fall of river water are major urban flood factors.Frequently-flooded city is mostly related to urban location,62% of the urban flood happenned in only 17% counties.Sudden local city flood in Shaanxi province in the Qing dynasty was characteristic of the flood.Human factors in urban floods are extensive,covert and severity,regional human production and living activities,and their strategies and measures in copying with the flood,determines frequency and degree of the urban flood.Fully understand and grasp the role of human factors in urban flood is our fundamental task in thinking urban flood mechanism.
