自工业革命后，人类加速了改造自然的进程，专注于科技进步和经济发展，但却导致生态环境日益恶化，环境问题开始影响人们的生活的方方面面，因此也越来越广泛的受到社会各界的重视和关注，人们开始意识到自己正面临着多重的生态考验。人们逐渐开始思考，人类与自然的关系究竟为何？大自然可以看作是人类所拥有的财产吗？自然本身是否有内在价值呢？青春期是一个人的人格形成和发展的关键时期，在高中阶段的青少年，他们的推理能力、辩证逻辑思维都迅速发展并趋于成熟，其价值观、以及道德意识也处于高度发展阶段，是树立环境伦理观念的重要时期。 因此，本研究将关注高中生的环境伦理观念，通过抽取被试填写环境两难道德问卷，让被试从保护环境与非保护环境的两难情境下写下双方背后的理由，即环境道德推理。根据问卷使用Nvivo11.0对高中生的环境道德推理进行质性编码分析，并根据人口学因素进行量化统计，最后将量化结果与成熟量表环境关心量表、自然相关性量表以及网络成瘾量表进行相关和回归分析。 研究结果显示：通过质性分析，被试对保护环境的环境道德推理主要可分为人类中心主义和非人类中心主义，并能够进行细致编码。通过量化分析，环境保护倾向与环境伦理倾向在年龄、家庭所在地、独生子女、对自然的喜爱程度以及自然经历等方面存在显著差异。高中生的环境伦理倾向对环境态度部分有正向影响，环境态度对他们的环境保护倾向有显著的正向影响，网络成瘾对环境伦理倾向有显著的负向影响。

Environment of high school students moral reasoning according to the questionnaire using Nvivo11.0 qualitative coding analysis, quantitative and according to the demographic factors, Finally the quantitative results and New Ecological Paradigm(NEP),Nature relatedness(NR) and Diagnostic Questionnaire(DQ) correlation and regression analysis. The results show that the environmental moral reasoning of the protected environment can be divided into anthropocentrism and non-anthropocentrism. Moral reasoning about non-environmental protection also has a non-anthropocentric perspective. Through quantitative analysis, There are significant differences in environmental protection tendencies and environmental ethical tendencies in age, home place, one child, love to nature, and natural experience.
