生態概念---LID(Low Impact Development)

Landscape and IT: 景觀植物搜尋系統

低衝擊性開發(LID)是一種利用蒸散、滲透和透過雨水管理的利用來管理水資源及水汙染，藉此避免或減少人為開發對溪流、河流、湖岸環境以及地下水的污染。

LID的技術與傳統的方式(草溝、滯留池)不同在於利用分散和小規模源頭管理的方式來對暴雨產生的逕流及污染進行控制，使開發地區盡量接近自然的水循環。

LID的方式包括屋頂花園、雨水花園、綠色街道等，均可降低逕流量、延遲洪峰流量、減低都市排水系統的壓力、減少回收雨水的成本、美化環境、降低建築物屋頂的溫度等等。

LID is an approach to land development (or re-development) that works with nature to manage stormwater as close to its source as possible.

LID principles:
1.preserving and recreating natural landscape features
2.minimizing effective imperviousness to create functional and appealing site drainage that treat stormwater as a resource rather than a waste product.

LID practices:
1.bioretention facilities
2.rain gardens
3.vegetated rooftops
4.rain barrels
5.permeable pavements.

LID effectiveness:
By implementing LID principles and practices, water can be managed in a way that reduces the impact of built areas and promotes the natural movement of water within an ecosystem or watershed. Applied on a broad scale, LID can maintain or restore a watershed's hydrologic and ecological functions.
