Abstract: Things in nature do not always have an equal value to mankind, nor do they necessarily exist in available or useful forms. In fact, contradictions often occur between human activities and natural environment.A modern ecosystem is a comprehensive combination of natural ecosystem and social system on the basis of material and energy utilization. According to the principle of ecological economics, a three-dimensional production-ecosystem can be established to derive all potential advantages from climate, topography, soils, water and vegetation without damaging the ecological stableness. Such an ecosystem can be achieved through its structural improvement, entropy reduction and efficiency promotion. Thus, a master plan is needed for the appropriate development of agriculture, forestry, animal husbandlry, fishery and sideline production as well as for rational development of cities, industries and communications.
