摘要
香港地少人多,市区人口密度之高,为世界之冠,超过5300人/km2。为制造出更多的平地空间,改造斜坡便成为香港市区发展的重要因素之一。早期人工斜坡的设计,多以结构体之安全性和稳定性为考量。随着市民环境保护意识之提高,现今的斜坡设计,除了须满足一般之城市规划要求外,更需考虑环境之美化和生态之效益。本文介绍生态工法设计在香港斜坡工程上的各种应用,以探讨其优劣处、局限性、可行性和综合效益。
The hilly topography makes Hong Kong one of the most densely populated cities in the world. The population density in some urban districts is as high as 5 300 person/km2. In order to meet the land demand for city growth, slope engineering has become an integral component of urban development in Hong Kong. In the old days, key considerations for slope were safety and stability. While the environmental awareness of the general public is increasing, recent slope design not only complies engineering standards and requirements but also incorporates ideas of environmental aesthetics and ecological values. This paper first introduces various applications of bio-mitigation measures for slope improvement in Hong Kong, then their strengths, limitations, feasibility and integrated benefits are discussed and evaluated.
