摘要
改善生态是风景园林的3大作用之一,衡量生态功能的变化是衡量居住区环境变化的一个重要方面。从生态服务功能的角度出发,提出生态服务功能补偿的概念,并对4个相关指标,即绿当量、径流、温度和固碳量来进行测度。绿当量从总体上反映了生态服务功能的变化,而其他3个指标分别从气候、水文以及对二氧化碳固定等人类对环境主要影响的方面进行了测度,通过对比居住用地建设前后指标的变化情况,更为定量和定性地了解建设对环境的影响,从而为绿地的规划和配置提供指导。以扬州海德公园居住区为例进行了实例分析。
Ecological function is one of the three basic functions of landscape.It is the main aspect of evaluating the ecological function changes of residential area.The article stands on the point of ecological service function and proposes the concept of ecological service compensation.It uses four related indices to measure the changes,which are green equivalent,runoff,temperature and carbon fixation.The green equivalent reflects the changes of ecological service function generally,while the other three indices measure human influence on environment from the aspects of climate,water and carbon dioxide fixation.By comparing the indices changes before and after the residential area construction,the influence of construction on environment can be understood more quantitatively and qualitatively,and the information can guide the green space planning and arrangement.The article also uses the Haide Park Residential Community as an example to illustrate the analysis process.
