建造功能性湿地的开拓性技术

Pioneered Techniques for Establishing Functional Wetland Environments

湿地修复往往是工程项目中的重要组成部分。为了能成功地修复和改善湿地,经常需要对现有的水力系统做大规模的变动。这些看来简单而自然的系统,却往往对工程师们提出很高的要求。工程师的职能是在满足所有这些有时相互矛盾要求的前提下提出一个符合人类和自然需要的,并能在允许的资金和时间之内建成的工程设计。在加利福尼亚州非常都市化的洛杉矶市附近,大规模的水文和湿地修复的BolsaChica工程是一个很好的工程实例。

Wetlands are often an imporlant environments. Large-scale changes component of projects aimed at to existing hydraulic regimes must establishing attractive and sustainable often be made to achieve success with wetland enhancement and restoration projects. While these kinds of projects appear to be simple natural systems, they present to the engineer a complicated system and a dearlh of information needed to supporl proper engineering analyses and design. The engineer＇s job is to meet all of these sometimes conflicting requirements with a project design that provides for the needs of man and of nature, and can be built with funds and time available. This process was illustrated with the Bolsa Chica Lowlands Project, a large-scale hydrologic and wetland restoration project located in a heavily urbanized area near Los Angeles, California.
