摘要
根据景观设计基金会的定义,景观绩效是一项"衡量景观解决方案在实现其预设目标的同时满足可持续性方面的效率的指标"。景观绩效在近些年成为了一个非常热门的研究焦点,其理论框架建立在可持续性的三元体系之上:环境、经济和社会。建成景观设施的绩效可通过其环境、经济和社会效益的量化结果得到体现。本文记述了一项对一个范围约1 300hm2、采用了湿地治理系统和自然化景观的总体规划性社区所进行的景观绩效调查,并对其中的经验进行了总结。研究团队确定了环境、经济和社会衡量标准,收集了能够反映出该系统绩效成果的数据,并对水质、土壤肥力和草本植物多样性进行了调查。此外,研究团队还对潜在和实际利益进行了量化,包括固碳,以及通过减少草坪修剪、肥料施用和用于灌溉的饮用水而节省成本。文中对环境、经济和社会方面的效益成果进行了讨论,并对建设过程中和建成之后各个阶段的管理和维护事项的相关经验进行了总结。
Landscape performance,as defined by the Landscape Architecture Foundation,is 'the measure of efficiency with which landscape solutions fulfill their intended purpose and contribute toward sustainability.' It is becoming a popular research focus in recent years; and its theoretical framework is built upon the sustainability triad: environment,economy and society.Through the quantification of environmental,economic and social benefits of a built landscape,its performance can be determined.This paper presents results from a landscape performance investigation and the lessons learned from a 3,200-acre master planned community that employs a treatment wetland system and naturalized landscapes.The research team identified environmental,economic and social metrics,and then collected data that reveals the performance results of the installed systems.Water quality,soil fertility,and herbaceous plant diversity were investigated.In addition,the research team quantified potential and actual benefits,including sequestration of carbon dioxide,and cost savings through the use of reduced mowing,fertilizer use,and reduction of irrigation with potable water.Environmental,economic and social benefit results are discussed.Lessons learned from management and maintenance issues during and post construction phases are summarized.
