摘要:

为综合评估南方特色林下仿野生模式栽培金线莲的生态环境效应,应用生命周期评价方法,定量评估该模式所产生的环境影响。结果表明,林下套种模式生产1 kg金线莲耗用的不可再生资源、土地、水资源分别为16 702.27 MJ、0.58 m2和13.45 t,该模式充分利用林下空地,占用较少的土地资源。但该模式也带来较大的潜在环境影响,生态环境综合影响值为0.327 6,且以水体毒性和富营养化的潜在影响较大。每生产1 kg金线莲,全球变暖、环境酸化、富营养化、人体毒性、水体毒性、土壤毒性分别为2 405.83 kg CO2-eq、4.99 kg SO2-eq、1.43 kg PO4-eq、1.32 kg 1,4-DCB-eq、5.31 kg 1,4-DCB-eq和1.09 kg 1,4-DCB-eq;对环境的潜在负面影响以来源于农资系统为主,且以组培苗生产占比最高。林下生产金线莲需要在组培苗生产、农药施用等方面加以改进,以控制其产生的潜在环境影响。

Abstract:

In order to comprehensively evaluate the eco-environmental influence on characteristic imitation wild cultivation of Anoectochilus roxburghii under forest in Southern China, the life cycle assessment method was applied to quantitatively assess the environmental impact of this model. The results showed that life cycle environmental impacts of 1 kg of A. roxburghii cultivated under forest were 16 702.27 MJ of primary energy demand, 0.58 m2 of land use, and 13.45 t of water use, respectively, this model made full use of the open space under the forest and occupied less land resources. However, this model also brought great potential environmental impact, the aggregate life cycle environmental impact index was 0.327 6, and the potential impact of water toxicity and eutrophication was large. For 1 kg A. roxburghii life cycle environmental impacts of this model were 2 405.83 kg CO2-eq of global warming potential, 4.99 kg SO2-eq of acidification potential, 1.43 kg PO4-eq of eutrophication potential, 1.32, 5.31,1.09 kg 1,4-DCB-eq of human toxicity, water toxicity and soil toxicity, respectively. The potential negative impact on the environment was mainly based on the agricultural material system, and the production of tissue culture seedlings accounted for the highest proportion. Therefore, making improvements in tissue culture seedling production, pesticide application, etc. were the key ways to control the environmental impacts of A. roxburghii production under forest.
