| 摘 要： | 将信息熵、模糊理论和物元可拓集合有机地结合起来,充分考虑天然草地的覆盖度、可食风干牧草产量、牧草利用率、草群中优良牧草比率、草地可利用面积系数、羊单位需草地面积等指标,建立了基于信息熵的草地评价的模糊物元模型,对面向新疆准噶尔盆地西部的天然草地质量进行了综合评价,所得评价结果与灰色关联度模型基本一致,表明该方法是可行的,而且该模型理论清晰、简捷,便于计算机编程。

| Abstract: | Combining information entropy, fuzzy theory and matter element, considering the covering, yield, u-tilization, coefficient of utilizable area and area of grassland per sheep, a fuzzy matter element model is constructed based on information entropy of grassland type. The grassland quality of west Zunge'er basin Xinjiang were synthesize evaluated, the result was accord well with the model of gray correlation system. The theory of the model is clear and succinct, convenient for computer programming. |
