摘要
公路绿化是改善路域生态环境不可或缺的环节,其生态效益发挥决定于植物的选择与配置。在我国,公路绿化存在重景观、轻生态功能的倾向,难以最大限度发挥绿色植物的自然生产能力。因此,运用新型绿化指标衡量公路绿化生态效益、考量企业绿化绩效,对于指导公路绿化建设具有积极意义。将绿量概念引入到公路绿化建设中,详细阐述绿量的含义与计算方法,并提出实现途径。
The expressway afforestation is a critical part to improve the ecological environment in expressway area, and the development of its ecological benefits is determined by choice and configuration of plants. In China , the present expressway afforestation has a tendency of attaching importance to landscapes but despising ecological functions, so it is hard to develop the natural production capacity of green plants to most extent. Therefore, exploitation of new green indices to measure the ecological benefits of expressway afforestation and to evaluate the afforestation achievements of enterprises has positive meaning for guiding the expressway afforestation construction. This paper introduces the ＂Green Quantity＂ concept into the expressway afforestation construction and elaborates the meaning and calculating methods of the Green Quantity in detail, and then proposes the realizing ways.
