历史时期浙东滨海平原地区水井功能与供水地位的变化

Changes of Well Function and Water Supply Status in the East Zhejiang Coastal Plain in Historical Periods

在浙东滨海平原开发的早期,水井分布在南部的低山丘陵与冲积扇平原的交接地带,水井供应淡水的便捷性对于小型农业灌溉和聚落兴起发挥了至关重要的作用。随着该区经济开发的深入及河湖水利体系的完善,水井的供水地位逐渐下降,但其与聚落的伴生关系一直存续。宋代以后,浙东滨海平原持续向外淤涨,在新成陆平原的盐场地区以及陆续形成的城镇聚落,由于淡水河流水系的延伸和水利体系的构建需要一定的时间过程,水井在该区经济开发和聚落扩张中仍然长期发挥着重要的供水作用。

In the early development period of the coastal plain of eastern Zhejiang,water wells were distributed in the intersection of the southern low hills and alluvial fan plains.The convenience of supplying fresh water from water wells played a crucial role in small-scale agricultural irrigation and the rise of settlements.With the deepening of economic development in this area and the improvement of river and lake water conservancy systems,the water supply status of wells has gradually declined,but its associated relationship with settlements has always existed.After the Song Dynasty,the coastal plain of eastern Zhejiang continued to silt up and swell outwards.In the salt field area of the emerging Plain and the successively formed urban settlements,due to the extension of the freshwater river system and the construction of the water conservancy system requiring a certain time process,the wells still played an important water supply role for a long time with the economic development and settlement expansion of the area.
