摘 要: 在收集了大量资料的基础上,依据历史分析的方法,将上海地区水系演变分为3个时期:黄埔水系形成期,太湖主要出海通道由吴淞江迁移至黄浦江;局部河道剧烈变动期,黄浦江河口段深水航道形成和中心城区中小河道的大规模消亡;河网综合治理期,河网分片防洪排涝和河网园田化。各时期水系演变的驱动力是自然变迁和防洪减灾、航运和城市化发展、全面的兴利除害,水系演变的强度也由弱变强。据此对平原河网水系的演变过程和人类治理的措施有一个比较清晰的认识,得到两者之间的响应关系,并提出今后人类在开发和治理平原水系时,要避免或减少人类活动对水系演变的负面影响。
关 键 词: 地理学;水系演变;历史分析;人类活动;平原河网

Abstract: A great deal of data was collected for the study of the river system change in Shanghai area. According to a historical analysis, the whole process of river system change in Shanghai was divided into three stages in this paper, the first is when Huangpu River system was formed and became the main outlet of Taihu Basin, the second is when river network in some local area was dramatically changed especially in the core area of Shanghai, and the final is when 14 water conservation zones were completely built for water resources management in Shanghai. It is concluded that the driving forces of the river system change in Shanghai were the natural change, flood control, development of shipping and urbanization, and the synthetical treatment respectively for the three stages, and the intensity of change became more and more strong stage by stage. Based on the study, it is proposed that the negative effect of human activities on river system should be avoided or reduced when we develop and manage the water resource in tidal plain.
Key words: geography; river system change; historical analysis method; human activities; plain river network
