Study On Emergy Evaluation Method Of Comprehensive Benefit Of Humic Agriculrtural Material

Humic primary products has significant economic, social and environmental benefits,so it has received widespread attention and the areas of application has increased year after year. Exploitation and production of humic primary products is regarded as the morning sun of new age.It is essential to establish a scientific evaluation indicator system and evaluation method. The indicator system and method can evaluate the economic, social, environmental benefits scientifically and correctly. It's a way of great practical significance which could enhance the awareness of value and benefit of humic primary products, promote the industrial development of humic primary products, promote agricultural development and rural progress, increase the income of peasants and protect environment and so on.Meanwhile, works in exploring ways of evaluation indicator system and evaluation method also have important theoretical significance in enriching the discipline system, innovating assessment methods.Humic primary products has economic, social and environmental value of three dimension and benefits features.The aim of this text is evaluating value and benefits of humic primary products synthetically and quantificationally. This text takes emergy analysis (EMA) theory and methods to establish new evaluation method--emergy evaluation method,it could provide a new assessment of the evaluation system and evaluation tools. On the basis of emergy evaluation indicator system and evaluation methods established, comprehensive quantitative evaluation is conducted for Compressed Integration Substrate(CIS)and conventional breeding from three aspects which is the economic, environmental and social benefits,then certificated by the traditional evaluation method. The results show that the emergy evaluation can greatly simplify the evaluation process of humic primary products. The results also show that distribution of weight is objective and scientific,evaluation conclusions are scientific and reliable. Emergy evaluation also have better spread and foreground in evaluating other agricultural materials to the economic, social, environmental effects.This method is a new simplified method in evaluating synthetical benefits of humic primary products objectively and quantificationally.
