Comprehensive Evaluation And Economic Benefit Analysis Of Crop Straw Recycling

Crop straw is a kind of renewable biomass resources with a variety of uses.It is one of the key links to strengthen the comprehensive utilization of crop straw to build a resource-saving and environment-friendly society.China is the world's largest producer of straw,but for a long time to receive influence people's consumption concept,life style,rural straw resources in China in high consumption,high pollution and low output,a lot of straw discarded or burned,not reasonable utilization.How to change the mode of economic development,to explore the optimal utilization of crop straw,the comprehensive management of crop straw has become one of the key issues of sustainable development of agriculture.This paper takes Shouxian County in Anhui Province as the study object,this paper expounds the necessity of comprehensive recovery and utilization of crop straw,on the basis,introduces five methods of using the current crop straw resources in China,combined with the specific situation of Shouxian County straw recycling,from the operation process,the integrated cost,the advantages and disadvantages of the methods are analyzed in detail in Shouxian County four kinds of commonly used straw recycling method.Then,on the basis of studying the theory of fuzzy analytic hierarchy process(AHP),this paper analyzes the basis of the fuzzy AHP method for comprehensive evaluation of the straw recycling method.At the same time,the index system of comprehensive evaluation of straw recycling method was established,and based on the fuzzy analytic hierarchy process(AHP),the comprehensive evaluation process of the four methods was given.Finally,based on the comprehensive evaluation results of the straw recycling method of the third chapter,this paper analyzes the economic benefits of the comprehensive utilization of the straw compression into the biomass straw pellet plant.Based on the related theories of economic benefit evaluation on the related index system selected economic benefit analysis of straw biomass pellet fuel project and analyzed its economic rationality,provide basis for establishing biomass straw particle dye plant in Shouxian County.
