Basic Principles of Low Impact Development低影响开发的基本原理 Daniel Medina, PhD 丹尼尔 麦地那，博士 Atkins 阿特金斯 Material by Steve Trinkaus Trinhaus Engineering, LLC 材料提供，Steve Trinkaus Trinhaus Engineering，有限公司 What is Low Impact Development?什么是低影响开发 LID is an ecologically friendly approach to site development and stormwater management that aims to mitigate development impacts to land, water, and air. The approach emphasizes the integration of site design and planning techniques that conserve natural systems and hydrologic functions on a site. LID是一种生态环境友好的场地开发和雨水管理方式，旨在减轻开发对陆地，水源和空气造成的影响。这个方法强调场地设计和技术规划的整合，注重保护自然系统和场地水文功能。 The Old Way传统方法 Source: University of Arkansas Community Design Center 硬工程 机械学的 The New Way新方式 Source: University of Arkansas Community Design Center 软工程 生物学的 How does LID work?LID如何奏效？ Managing rainfall using uniformly distributed decentralized micro-scale controls. LID’s goal is to mimic a site’s original hydrology by using design techniques that minimize, infiltrate, evapotranspire, filter, and store and detain runoff close to where it is generated. 使用均匀分布分散式微尺度控制来管理雨水。LID的目标是模仿场地原本的水文，使用的技术设计有最小化，渗透，蒸发蒸腾，过滤，贮存和滞留靠近发生地的径流。 Rainfall as a resource降雨是一种资源 Rainfall is a resource to be used recycled within the environment not something to be quickly disposed of 降雨是一种资源，可在环境内被循环并使用，不是应该迅速弃置的东西。 Principles of Low Impact Development低影响开发的基本原理 Site planning storm water management are integrated at the initial design phases of a project 要把场地规划和雨水管理在项目的初级设计阶段就整合到一起。 Native soils and vegetation are protected and strategically utilized throughout the site to slow down, store, and infiltrate runoff 天然土壤和植被应被保护和遍及场地的战略性利用，从而减缓，贮存和渗透径流。 Conventional Development 8 Conventional site design 传统场地设计 LID Development 9 LID controls added as an afterthought 事后添加的LID控制 This is not LID 这并不是LID Five Basic Tools of LIDLID的5个基础工具 Encourage conservation measures 鼓励保护措施 Reduce impervious areas 减少不透水面积 Use landscape features to slow down runoff 使用景观特征来减缓径流 Use multiple measures
