| This text focuses on the research about the branch of environmental science,such as, environmental resource science,environmental economics, environmental law, environmental control engineering and technical studies, environmental management, proposes the conception of asymmetry in the environment,combined theory of asymmetry of information and differences in different districts,we classifies lists systematically and analyses systematicly a variety of asymmetries in the environment. Main research contents are divided into four parts:The first part is about classification and manifestations of asymmetries in the environment.First, asymmetries are studied within the context of the environment in which Environmental Sciences are studied.The contents that can be best reflects the characteristics of asymmetry are singled out as research object,for the following nine aspects of the performance of the asymmetry in Environmental resources, environmental capacity, environmental information, environmental technology, environmental standards, environmental regulations, environmental awareness, environment will, environmental values.Second,we describe the asymmetries, explain quantitative of the asymmetries by various statistical data, survey data, analog data,and chart. Last,we analyse these data qualitative.The second part is about cause of asymmetries in the environment. First,we analyse the cause of nine aspects of the performance of the asymmetry in-depth. Second,we sum up all the cause, express systematicly the root cause from the following four angles:the difference in spatial distribution,chronological, the difference in individual endowments of human and the difference in natural resources endowment. Although each type of asymmetry often was caused by mixed effects of multiple causes, but also it shows some some of the dominant factors,such as: the difference in spatial distribution which is mainly reflected in environmental standards asymmetric and environmental regulations asymmetric, chronological which is mainly reflected in environmental information asymmetric and environmental technology asymmetric, the difference in individual endowments of human which is mainly reflected in environmental awareness asymmetric and environment will asymmetric,the difference in natural resources endowment which is mainly reflected in Environmental resources asymmetric and environmental capacity asymmetric.The third part is about impact of asymmetries in the environment. asymmetries in the environment will impact on the environment system.Some impact is positive and necessary; some impact is negative and it should not be continued to exist.The fourth part is about application of asymmetries in the environment. Based on the results of the analysis about impact of asymmetry,we divide it into two classification which are application about favorable asymmetric and avoiding negative asymmetry. |
