城市水土生态的大地格局原理实践探索

摘要

Shenzhen has been suffering for water and soil erosion for 20 years. It is necessary to employ lager concepts and new methods to solve today’s urban soil and water ecology problems. This paper argues that the principle of soil and water ecology is the standard of human behavior and scientific principle concerning the preservation, restoration and construction of the ecosystem of soil and water. The author also puts forward that the macro-scale of soil and water ecology principle can be interpreted as the landscape pattern principle and its contents. At the end, six aspects of the practice and innovation system of urban soil and water ecology principle are concluded, which are:soil and water ecological culture, development principle for balanced earthwork, optimal control of road slope difference and green protection principle, principle for restoration and preservation of the eco-functions of rivers, principle for ecological restoration of bare mountains’ gaps, and configuration principle of the erosion prevention and control of developing area.%深圳市的城市水土流失出现至今已20年了，当今城市水土生态问题需要宏观的理念和全新的方法。从城市出现的水土生态问题出发，论述了水土生态原理是与水土有关的生态系统的保护、修复、建设的人类行为准则和科学原理，提出水土生态原理的宏观尺度可理解为大地格局原则及其具体内容，并总结出城市水土生态原理的实践创新体系的六大方面：水土生态文化、土石方平衡的开发准则、道路边坡高差的优化控制及绿色防护原则、恢复与维护河流的生态功能原则、裸露山体缺口的生态修复原理、开发区流失防控配置原理等。
