Abstract: The development of organic industry is closely related with the regional ecological environment, and ecological environmental impact assessment of this type of industry is critical for balanced economic performance with full ecological and environmental consideration. Based on the analysis of environmental requirements of organic products, the paper reviewed the effects of organic industry on different eco-environmental factors, and analyzed the full processes characteristics of influence of organic industrial chain on ecology and environment along with the environmental impacts of each node of organic industry. Based on different types of organic industry, a relational coupling of organic industry and ecological environment was analyzed. Furthermore, a comparison between environmental impacts of organic agriculture and those of conventional agriculture showed some significant ecological environmental advantages of organic agriculture. In terms of environmental benefits, the results showed that the effect of organic agriculture on the environment was 68% while that of conventional agriculture was 50%. The full process of current analysis was based on resource consumption, environmental load, energy use, economic cost and human health, driven by the concept of life cycle assessment (LCA). Moreover, ecological index was used to quantitatively characterize organic industrial environmental impacts by classifying multi-factor indicators and computing individual weights to construct the evaluation system. Because of complexity of data acquisition and immaturity of organic industry, the evaluation system of influence of organic industry on the ecology and environment needed further exploration.
