Ecological civilization characterized a new state of the relationship between human and nature. It is the expanding and sublimation of material civilization, spiritual civilization, political civilization and social civilization for human race. According to the requirements of economic, social and ecological practical possibility, the relationship between human and land under the development of human society must be optimized; the sustainable development must be realized in the constructing of ecological civilization.Marxism is the grand academic system in the study of development regularity of nature, society and human thinking. In the Marxism's theory, it is the two themes to realize the reconciliation of human and nature, also to realize the reconciliation of human society itself. Marxism believes that the development of the future society not only to solve the contradiction of alienation of human's relationship but also to deal with the problem of the alienation between man and nature. It is a masterstroke for Marx and Engels to show great attention to the relationship between human and nature in Marxism classical works. From philosophic view, Marxism emphasize on either preexistence of nature to human or mankind dependence to nature. They also emphasize the nature of mankind and human's social attribute. Marxism stress that human not only engages in nature to produce but also must symbiosis and coexistence with the nature. They emphasize on the purpose of human activities and the regularity of natural ecosystem. The nature point, the history point, and the dialectical developing point about ecological thought implicated in Marxist classical works reveals the relationship between man and nature on the ultimate concern.Ecological Marxist and the theory of construction of ecological civilization under the scientific thought of development are the amplification and innovation of Marxism's ecological idea and implication in the contemporary society. Ecological Marxist have constructed the ecological view of Marxist historical materialism, combed the implication of ecological view in Marxist's dialectical materialism. The ecological Marxism deeply criticized the ecological crisis, the alienation of nature and human from the view of institution, techniques and consumption in contemporary society in western countries, revealed the fundamental reason of ecological crisis in the western nations. Ecology Marxism advocate to solve ecological crisis by establishing ecological socialism, realizing the harmony between human and nature and achieve the goals of sustainable development in human society. Ecological Civilization Theory is a comprehensive scientific guide to break the ecological and environmental problems in China. The construction of ecological civilization stressed to exploit and to transform the nature, making an orderly ecological operation mechanism and good living environment simultaneously. The core of the construction of ecological civilization is to create a new development pattern and a new human-land to achieve a harmony state between human and nature by scientific development. The construction of ecological civilization not only indicates a state of accumulation and growth of social material and wealth, but also embodies the progress of ability for human relationship with nature, coordinating and protecting of the nature. The construction of ecological civilization theory reflects the Communist Party of China develops and innovate the Marxist ideological thought.The natural ecological environment in western China is vulnerable, while its economy is underdeveloped. In the dilemma of developing economic and fragile ecological, the western region in China bears a heavy task both with accelerating the development of its economy and transforming poverty and backwardness. When the environment gets worsening, they also faced with the enormous pressure to strengthen and protect the ecological environment. We must understand signality to the construction of ecological civilization from strategic view in western China. We also must correctly handle the relationship between economic development and environmental protect, overcoming the disadvantages of traditional development mode, and gradually exploring a resource-conserving, environment-friendly economy development mode. From the perspective of the "reconciliation" of relationship between human and nature, only metabolism of substance of social economic system and natural ecological system in western China are realized, it can form a harmony relationship between human and nature.Western region is not only a strategically area for China's economic sustainable development in the future, but also an important barrier of ecological security. It is a rational choice for constructing socialist ecological civilization in the western region of China. Currently, the unenlightened thought, the weak economic foundation, the fragile natural ecological environment and the lag of the institutional improvement are key problems with which China's western area faced.Under the guidance of scientific thought of development, western region in China must innovate its production and consumption patterns, develop its ecological industry, improve its environmental quality, balance its urban and rural development, advance their development to a civilized mode with production development, life affluence and good ecological environment. The harmony between human and nature must be promoted. For construct the ecological civilization in western region of China, first, they must put the scientific thought of development into practice, strengthening the ecological awareness, establishing ecological civilization values and outlook firmly. Second, they need to make a new "people-oriented" and interactive relationship between the human and the nature. Third, they should change the traditional economic growth mode, realize it to a green and low-carbon track, constructing the industrial development foundation in the area and formatting a sustainable development pattern. Fourth, they must complete institutions while constructing their behavior criterion system into economic developing, social progressing and ecological civilizing mode. |
