基于AHP和熵权法对淮河源4类饲草的评价

Evaluation on Four Kind of Forages in the Huaihe River Source Area Base on AHP and Entropy Weight Method

为促进淮河源地区饲草产业发展,通过选取生产机械化水平、产品经济效益、营养价值、环境影响程度和资源供给5个方面共12个指标,采用熵权法和层次分析法相结合的方法对淮河源常见的4类饲草进行综合评价。结果表明,巨菌草(Pennisetum sp.)、青蒿(Artemisia carvifolia)、狗尾草(Setaria viridis)、青贮玉米(Zea mays)和紫花苜蓿(Medicago sati?va)综合评价值为0.977、0.904、0.950、0.948、0.927,显示出淮河源地区畜牧业集约化程度差,导致栽培饲草和野生饲草相比没有任何优势,评价指数高的巨菌草等饲草没有得到推广应用。对评价结果分析表明,该地区优质饲草产量高、可提供的生产资源多,有较大发展潜力。

In order to improve the development of forage grass industry in the Huaihe River source area, 12 indexes of five aspects were selected to evaluate four kind of forages, which include the level of mechanization, economic benefit of the product, the nutritional value, the degree of environmental impact and the supply of resources by using the combined method of entropy weight and AHP. The results showed that the comprehensive evaluation indexes of Pennisetum sp., Artemisia carvifolia, Setaria viridis, silage maize and alfalfa were respectively 0.977, 0.904, 0.950,0.948 and 0.927, which indicated the cultivated forages had no advantage compared with the wild forage grass because of the lowly intensive animal husbandry production. The Pennisetum sp. of high evaluation index has not been popularized. The analysis of the evaluation results showed that the high quality forage in this area has high yield and abundant production resources, and has great potential for development.
