The orderliness of dissipative structure is dependent on the mutual contacts between various factors, it is a macroscopical and universal concept, which reflects the degree of internal relations about the system. This paper is based on the theory of dissipative structure, reveals the essence of the theory of dissipative structure and its formative qualification, finally we expounds that the dissipative structure is the origination of orderliness about organism. In a certain sense, the process of life is complicated physical and chemic process. This paper proposes a new view about the purpose of life through the analysis of vital phenomena: the instinctive purpose of life is to enhance the orderliness about the dissipative structure of oneself, the import of negentropy is just a means to achieve the instinctive purpose of life. In addition, this paper makes a detailed analysis of the nature of the orderliness for life as a dissipative structure.
