论能源植物的定义及其评价指标体系的建立

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。

Discussion on definition of energy plant and its evaluation indicator system

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 apphcations, 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.
