论能源植物的定义及其评价指标体系的建立

摘要

本文探讨并总结了能源植物的定义，认为能源植物是指具有较高合成能源或替代能源产品能力的植物，并根据用途分为4类：1.富含类似石油成分的能源植物；2.富含高糖、高淀粉和纤维素等碳水化合物或者碳氢化合物的能源植物；3.富含油脂和挥发油的能源植物；4.速生丰产薪炭植物。根据不同能源植物的类型建立了3个评价指标体系，分别是：1.富含油、淀粉、糖、橡胶等类能源植物评价指标体系；2.木质纤维素能源植物评价指标体系；3.薪炭能源植物评价指标体系，筛选出3个一级指标：能源含量、生物质产量和生态适应性。通过数据实践检验，表明建立的评价指标体系可基本满足能源植物筛选工作的需要。%The paper discusses and redefines “energy plant”. Energy plants are those which have the high capability of synthe-sizing energy products or alternative energy products. Considering applications, they can be divided into four types: 1.energy plants which are abound in elements similar to petroleum; 2.energy plants which are abound in hydrocarbon or carbohydrate, such as sugar, starch and cellulose, and so on; 3.energy plants which are abound in grease and volatile oil; 4.energy plants with fast-grow and high-yield for firewood. Three evaluation indicator systems are established corresponding to different types of energy plants, namely: 1.evaluation indicator system for energy plants which are abound in oil, starch, sugar and rubber, and so on. 2.evaluation indicator system for energy plants which are abound in lignocellu-loses. 3.evaluation indicator system for firewood energy plants. Three first -level indicators are screened out: energy content, biomass yield and ecological adaptability. Through data testing, these evaluation indicator systems can satisfy the need of energy plants' screening works.
