Research On The Evaluation Of Straw Resource And The Development Of Scale-Up Straw Energy Utilization In Jiangsu Province

Energy is the important material base of the national economic and social development. The energy supply security has become one of major factors of social and economic development. Since the world energy crisis in the 1970s, many countries have paid more and more attention to the exploitation of biomass energy and bio-fuel. And what's more, biomass as renewable energy resources will occupy an important position in future energy structure. In recent years, with the rapid economic development in our countries, many areas have emerged electricity in short supply, especially Jiangsu province. So it is an effective way to solve the problem of energy shortage effectively, that this passage uses plenty of straw resources fully and reasonably.This subject is based on the guidance of the theory of survey and assessment. And according to historical records and investigations from 1999 to 2009, this study got various crops' output in every region of Jiangsu province. Also by the calculation of the ratio of straw to grain and collection coefficient, it is successful to get theoretical output and collected output of the straws. This passage is on the analysis of the actual use state and distribution of straw resources in 2009. And GM(1,1)model is the eventual adoption to predict straws' theoretical output and collected output in Jiangsu during next ten years. Referring to the project "Biomass Energy Resoures, Assessment and Programming in Jiangsu Province", it established the index system in straws' scale-up utilization technology. With the AHP, it got comprehensive evaluation on the technology about biomass power generation, straw solidification as fuel and straw gasification, and the analysis on the trend of the scale-up use of straw energy. According to conditions of straws resource in each region of Jiangsu, this passage bring out the key development and the structure of industry about straws' scale-up utilization. And also, it put forward the arrangement and scale of biomass power generation, straw gasification station and working points of straw solidification as fuel in future 5 to 10 years.This study analyzes the actual state of straws' units and distribution roundly, and discusses the future of straws' scale-up utilization, which provide a foundation for improvement of the rural economic and straws' comprehensive utilization. In addition, this passage provides development goals of straws' utilization for relevant government and supplies some suitable policy recommendations for straws' scale-up development. Finally, we hope to put forward scientific evidence of straws' scale-up utilization for investors in Jiangsu.
