摘要:
香港位处亚热带季风区，平均每年降雨约2000mm。因为季节雨量分布极不平均，加上一系列的人为因素，包括都市化造成土地利用改变、排水设施不足、垃圾或沙石堵塞河道等等，很多低洼地区在暴雨过后便出现水浸，严重影响当地居民生活和造成庞大的经济损失。有鉴及此，香港政府于60年代以前便积极整治河流。发展至今，整治的范围已遍及香港大部分的河流。初期的整治工程，着眼点是防洪，全由水文和工程的角度去考虑，使用最简单、直接的方法解决洪患。随着香港公众对环境的醒觉，近期的河道整治工程除了防止洪患外，还要顾及环境美化和生态保护等
Abstract:
Hong Kong experiences a subtropical monsoon climate whose average annual rainfall is about 2000 mm.Uneven seasonal distribution of rainfall plus a number of human factors, such as landuse change, inadequate drainage facilities and blockage due to garbage, contribute to frequent occurrences of flooding in some low lying areas after heavy rainstorms.To tackle this problem, Hong Kong Government has launched many channelization projects since 1960s.Up to now, most rivers in Hong Kong have been channelized to different extent.In the old days, the key consideration for channelization was drainage capacity.While the environmental awareness of the general public is increasing, recent channelization design not only meets drainage requirements but also incorporates ideas of environmental aesthetics and ecological values.It reviews the past development of channelization in Hong Kong, evaluates the strengths and limitations of channelization,and suggests recommendations for future improvement.
