摘　　要：本文测定了花棒、羊柴、柠条、沙拐枣、梭梭等五种固沙饲用灌木营养成分在生长期的变化。营养成分含量的高低是评价灌木饲用价值的主要依据，由于变化的不一致性和动态性，要定量地科学地评价其饲用价值，必须用综合指标来分析。本文对上述饲用植物进行了综合评价。Variation of nutrient in five species of shrubs was measured in growth season. Content of nutrient was a major base to evaluate the forage shrubs. Because of variation and dynamics of nutrient content in different seasons, it is necessary to use comperehensive index for quantitative and scientific analysis of forage shrubs. This paper evaluated the above five species of shrubs in comprehensive ways.
