摘要: 随着社会的不断发展,以CO2为主的温室气体排放量不断增加,引发一系列环境问题,如何有效减排固碳成为当前的热门话题。以往人们只关注植物的碳汇功能,但对园林苗圃内植物所产生的碳排放却鲜有关注。在本研究中,按照园林苗圃的不同类型,以天津市内的花圃、草圃、森林苗圃这三类园林苗圃为研究对象,构建其生命周期碳排放量化体系,使用碳排放系数法,选取燃油、水、电,化肥等碳源指标,对上述三类园林苗圃生命周期内的碳排放进行核算。研究结果表明,从整体来看各苗圃的碳排放主要集中在圃内养护阶段,园林苗圃在养护阶段产生的碳排放约为601 890 kg,花圃圃内产生的碳排放约为390 180 kg,森林苗圃产生的碳排放约90 080 kg。从养护阶段生产区域单位面积所产生的碳排放来看,花圃产生的碳排放为11.54 kg/m2,草圃为1.35 kg/m2,森林苗圃为0.13 kg/m2。植物在园林苗圃的生产生命周期内会产生大量的碳排放,主要碳源来自电、水、施肥和园艺资材,因此在植物景观设计实践中应当合理、恰当地使用温室花卉、草皮等植物材料。

Abstract: With the continuous development of society, CO2-based greenhouse gas emissions are increasing, triggering a series of environmental problems, how to effectively reduce emissions and carbon sequestration has become a current hot topic. In the past, people tend to pay attention to the carbon sink function of plants, but little attention has been paid to the carbon emissions generated during their production in nurseries.Therefore, we take three types of garden nurseries in Tianjin, namely, flower nursery, grass nursery and forest nursery, as the research object, construct their life cycle evaluation system, and use the carbon emission coefficient method to calculate the carbon emissions during the life cycle of the three types of garden nurseries by selecting the carbon source indexes such as transportation, electricity, water and horticultural materials. The calculation results show that the carbon emissions during the life cycle are mainly concentrated in the maintenance stage of the nursery, and from the overall point of view, the carbon emissions generated in the maintenance stage of the grass nursery are the largest at 601890 kg, followed by the carbon emissions generated in the maintenance stage of the flower nursery at 390180 kg, and the carbon emissions generated in the maintenance stage of the forest nursery are the smallest at 90080 kg. From the point of view of carbon emission per unit area of production area, the flower nursery produces the largest emission per unit area in the maintenance stage, followed by the grass nursery, and the forest nursery produces the smallest emission, which is 11.54 kg, 1.35 kg and 0.13 kg, respectively. Plants in the production of garden nurseries produce a large amount of carbon emissions during the production lifecycle, and the main sources of carbon are related to the use of electricity, water, fertilizers, and horticultural materials. Therefore, greenhouse flowers, turf and other plant materials should be used reasonably and appropriately in plant utilization practices.
