Sustainable Development Evaluation of Planting Eco- economic System Based on Emergy Analysis in Dezhou
摘要
Abstract
The emergy input and output were analyzed based on the theory and method of emergy analysis and statistical and investigating data of Dezhou in 2009. The results showed that the renewable environmental emergy, non - renewable industrial supplementary emergy, and renewable organic emergy was 4. 99% , 81.31% and 13.70% of the total emergy input respectively, in which, the specially emergy of fanning machinery was 57. 8% of not - renewable industrial supplementary emergy. It indicated that Dezhou farming ecological system mainly relied on the non - renewable industrial supplementary emergy input, and there was a high level of mechanization. The high transition rate of solar emergy, the high net emergy output rate and the high environmental loading rate showed that Dezhou had high level of planting model of agricultural modernization and big environmental pressure. Therefore, the main proposals for sustainable development of Dezhou planting industry were put forward as reducing non - renewable industrial supplementary emergy input to enhance the plantation development sustainability, regulating the input ratio of environmental resources and organic emergy to reduce the environmental load rate, and adjusting the planting structure to increase the net emergy output rate.关键词
