园艺投入品具有多种潜在的环境影响，可采用生命周期评价（LCA）方法对其进行综合评价。它被认为是通过识别、量化和评价环境中枯竭和释放的资源来分析生态系统的适当评价工具。基于此，本研究采用LCA技术和CExD分析方法，对伊朗桂兰省柑橘、榛子、猕猴桃、茶叶和西瓜等不同种植制度下的园艺作物环境危害进行了评价。应用LCA方法和ReCiPe2016，确定了园艺作物的人体健康、生态系统和资源3个环境指标。功能单位被认为是10吨园艺作物的产量。从环境的角度来看，果园排放和氮肥在所有系统中排放量最高，而榛子生产比其他园艺作物产生的污染更多。结果表明，在所有研究的园艺作物中，榛子生产需要更高的能量。环境影响和能源形式的比较表明，柑橘生产是最好的，因为在园艺产品中排放量最低。因此，这种作物建议用于园艺作物栽培。总的来说，柑橘种植系统的建模、有机肥的利用、旧设备的更换和灌溉系统的改进可以达到更可持续的园艺生产。(C) 2020 Elsevier Ltd.版权所有。
Horticultural inputs have various potential environmental impacts, which can be simultaneously evaluated by using the life cycle assessment (LCA) method. It is considered an appropriate evaluation tool to analyze ecosystems through recognizing, quantifying, and appraising resources depleted and released within the environment. Accordingly, in this work, environmental damages of horticultural crops are evaluated by using LCA technique and CExD analysis under different cropping systems including citrus, hazelnut, kiwifruit, tea, and watermelon in Guilan province of Iran. By applying LCA method and ReCiPe2016, three environmental indicators including human health, ecosystem and resources of the horticultural crops are determined. Functional unit is considered as 10 ton of horticultural crops yield. From the environmental viewpoint, On-Orchard emission and nitrogen fertilizer have the highest emissions in all systems, whilst more pollution is generated in hazelnut production than those in other horticultural crops. Results in CExD show that, amongst all studied horticultural crops, the hazelnut production entails higher energy amount. A comparison of environmental impacts and energy forms show that citrus production is the best, owing to the lowest values of emissions among horticultural productions. As such, this crop is suggested for horticultural crop cultivation. Generally, it can be concluded that modeling of citrus cropping system for other crops, utilization of organic fertilizers, replacement of worn out equipment and improvement of irrigation system can attain more sustainable horticultural production.
