薪炭林植物选择指标数值分析

THE QUANTITATIVE ANALYSIS FOR THE CHOICE INDEXES FOR SPECIES OF FUEL WOOD

根据薪炭林植物应具有热值高,抗旱性强的特点,文章选择了产量、热值、水势、组织含水量、自由水/束缚水和自然饱和亏六个特征指标,在单指标分析的基础上,又应用数值分析技术选出了沙棘、狼牙刺、山桃、柠条、沙打旺、草木樨、苜蓿、红豆草共8个优良的薪炭林植物种。

This paper chose six charactic indexes,yield,fuel value,water potential,tissue water content,ratio of free water to bound water and natural saturation deficit,according to the charactersitic that fuel wood plants should have higher and drought resistance.After com- paring each charactic indexes,eight fine species were selected by using of quantitative analysis technique,They are Hippophae rha- mnoides Linn.,Sophora vicifolia Hance.,Amygdalus davidiana(carr) Franch.,Caragana inlelmadia Kuang el H.C.Fu.,Astragalus adsu- rgens Pall.,Melilotus suaveolens Ledeb.,Medicago sativa L.and Onobrychis viciaefolia Scop.
