Abstract In order to determine the extent and the impact factors of the facilities vegetable production on environment, the environment impacts of three modes of vegetable production were assessed by the LCA. The results show that the main impacts of facility vegetable production on environment are energy depletion, fresh water depletion, global warming, acidification and eutrophication. The environment impact of far-ming system is greater than that of agriculture material system, while the environment impact of farming system by pollution-free way is 47.2% of the agriculture material system.The impact of transportation is slight. The Venlo-type green house impacts of energy depletion, global warming and acidification are 58.3, 32.5 and 15.1 times than those of person values in China, respectively. The solar-greenhouse impacts of fresh water depletion, human toxicity, fresh water toxicity and terrestrial toxicity are severe. The environment impacts of Venlo-greenhouse are 101 and 740 times than those of solar-greenhouse and pollution-free way, respectively.
