摘要: 城镇历史水系是长期与自然过程动态调适下构建的人工水系网络。总结其历史经验，对缓解当代城镇雨洪、水资源综合利用及特色危机等问题均有借鉴意义。本文以高山平川型典型山地城镇历史水系为研究对象，重点分析了历史水系的组织特征，提取“源—汇—流”水系结构，并进一步分别阐述“源”、“汇”、“流”三要素营造方式，及其城镇生产生活的调蓄、排流、景观营造等多功能关联，从而为当前山地城镇水系的适宜性规划实践提供理论支持。Abstract: Historical river system is the artificial water network formed through a long-term dynamic adjustment of the natural process. Summarizing the historical experience has reference meaning to relieve the contemporary rainwater of town, the water resources utilization and the identity crisis.This paper takes typical historic river system of town located in high mountain plains as the research object,focuses on the characteristics of its organizational structure, extracts the “source-sink-flow” structure of the whole river system, and further elaborate three building elements of“source”,“sink”,“flow”. It summed up that the “source-sink-flow” river system structure is a multifunction sustainable river structure with storage, drainage, landscape construction and other functions. Thus, it provides the theoretical support for practical application of the current water system planning of mountainous towns.
