摘要
城市生态补偿在城乡开发、城市规划等许多工作中具有重要的意义。为衡量城市生态补偿能力,本文提出了绿当量的概念,并以山东大学为例,探讨了对二氧化碳、降尘和二氧化硫的生态补偿方法。根据实际情况,以街道办事处为单元评价山东大学内现有绿地的生态补偿能力,并根据环境目标的要求,提出了各办事处需增加的公共绿地面积,为制定市区公共绿地配置规划提供了依据。计算结果表明,从总体上说,山东大学现有的绿色植物可补偿山东大学排放到大气中的二氧化碳的22.3%,二氧化硫的23.1%;其总吸尘能力略大于年排尘能力。绿当量概念和计算方法在山东大学城区公共绿地配置规划中的成功应用,表明它可对其它城市绿地生态补偿能力的评价和城市环境规划的制定发挥指导和借鉴作用。
Urban ecological compensation plays an important role in county development,city planning and many other works. In order to measure the abilities of urban ecological compensation and formulate the macroscopic planning for policymanagement, this article puts forward the concept of green equivalent and application methods of urban ecological compensation. Taking Jinan city as an example, the abilities of its existing greenland in each unit of subdistrict are evaluated and the areas of greenland to be enlarged according to the requirement of air environmental target are calculated. The results demonstrate that the green plant of Jinan city could compensate 22.3% of carbon dioxide and 23.1% of sulfurdioxide emission in the air,and its abilities of adsorbing dust is a little bigger than that of discharging dust. Owing to successful application of the concept and measuring methods of green equivalent in the public greenland planning of Jinan urban district, it may also be referential in directing other cities in ecological compensation evaluation of greenland and the design of environmental planning.
