Among the numerous definitions of ecological civilization, it can be summarized into three kinds of ecological civilization views: pure natural ecological civilization view, harmonious and unified ecological civilization view between man and nature and broad ecological civilization view. (1) pure natural ecological civilization view This is an ecological civilization view based on the harmony between man and nature. Its connotation is that human beings actively protect the objective world, actively improve and optimize the relationship between man and nature, and build a good ecological environment while transforming the objective world. The sum of material and spiritual achievements. The orientation of this ecological civilization is to achieve natural ecological balance on the basis of human protection and restoration of nature, and it is all the progress and positive results aimed at protecting and restoring the balance, stability and integrity of natural ecosystems including human beings. (2) Harmony and Unity between Man and Nature This is a harmonious and unified view of ecological civilization based on the naturalness and initiative of man and nature, which summarizes ecological civilization as all the progress and positive achievements of human beings aiming at the harmonious and unified naturalness and initiative of man and nature. That is, the essence of ecological civilization is the coordination and unity of human beings' protection and restoration of nature, transformation and transformation of nature, and the coordination and unity of realizing natural ecological balance and human economic goals, that is, the coordination and unity of "production development, affluent life and good ecology". It is not difficult to find that this kind of ecological civilization directly reveals the main reason of contemporary natural ecological crisis, that is, there is a serious imbalance and opposition between natural harmony and dynamic harmony between man and nature, or between natural ecological environment protection and economic development; At the same time, it also points out the inevitable way to solve the crisis, that is, the two must be coordinated and unified. This concept of ecological civilization itself covers the concept of pure natural ecological civilization. (3) Generalized Ecological Civilization This is an ecological civilization view based on the harmony between man and nature and between people, and its essence is the harmony of the generalized ecological system formed by the integration of human social system into natural ecological system. The broad view of ecological civilization holds that the essential requirement of ecological civilization is to realize the double harmony between man and nature and between man and man, so as to realize the sustainable development of society, economy and nature and the free and all-round development of man. Ecological civilization does not belong to the relationship with material civilization and spiritual civilization, and its generality, hierarchy and extensiveness are higher. [1] Obviously, the first view of ecological civilization aims to solve the pure ecological crisis, and the second view of ecological civilization aims to solve the problem of "ecology? The vicious circle of economy, the third view of ecological civilization aims to solve the generalized ecological crisis (natural ecosystem crisis and social system crisis). Therefore, the author believes that the concept of ecological civilization guiding the development of human society should adopt a broad connotation, that is, under the background of industrial civilization and under the guidance of the concept of harmonious development, the contradiction between ecological factors and social factors in the development of human society should be solved in a timely and coordinated manner to realize the goal of "people?"
