Research on Comprehensive Utilization Model of Straw in Heilongjiang Province Based on Resource Endowment

Heilongjiang Province is rich in crop straw resources, but for a long time there have been problems such as low utilization rate and lack of comprehensive straw utilization models suitable for local conditions, which formed The so-called "straw dilemma".This paper analyzes the current situation of comprehensive utilization of straw in Heilongjiang Province on the basis of researching related documents, and points out the existing problems. And through the method of RPR calculation, the various regions of Heilongjiang Province are divided into three types: straw resource-rich area, straw resource-general area, and straw resource-poor area according to the amount of straw resources.At last, this paper combines the characteristics of various utilization methods to construct a comprehensive utilization industrial model and operation model of crop straw suitable for different straw resources regions of Heilongjiang Province.
