非可逆性

Through analysis, the thesis thinks that the economical nature of environment goods cannot be generalized by public goods or private goods, its nature has been changing between the two extremes. The environment goods is on one hand reflected in some legal arrangement in international environment statute, where the focus is the whole humankind, for example,"common heritage"; on the other hand, it is also reflected in the rules that protecting private rights in civil legal system, where the focus is the individual, for example,"the right of environment personality ". The essential part of environment justice is the social distribution of environment benefits and burdens, so the thesis centers on the social peculiarities of environment goods as social burdens and as social benefits. In detail, environment benefits are related both to property and to personality, and they are also un-produced, non-substitutive and prima goods as living resources; environment burdens are composed of LULUs and many uncertain and irreversible environment risks.

通过分析，本文认为环境物品的经济性质不能单纯地用公共物品或私人物品进行概括，其性质在此两极之间会发生变动；而法律构造中的环境物品一方面体现在国际环境法中的主要以&类&为主体的各种制度安排中，例如&人类共同遗产&，另一方面则体现在民法体系中以&个人&为主体的各种私权保护的规则中，如环境人格权等；接下来，鉴于环境正义的核心是环境利益与负担的社会分配，所以本文重点探讨了作为一种利益和作为一种负担存在的环境物品的各种独特的社会属性，具体而言，环境利益具有财产属性、人格属性、非制造性、不可替代性以及作为生存资源的前提性；而环境负担则具体包括&不可欲的局域性土地利用方式&和具有科学不确定性和不可逆性的环境风险。
