摘要: [目的] 明确内蒙古自治区东乌珠穆沁旗草地植物群落营养成分现状,促进草地畜牧业可持续发展和草地生态环境改善。[方法] 该研究以东乌珠穆沁旗10个乡镇(苏木)的草地植物群落为研究对象,分析其营养成分含量,结合对应分析方法,阐释不同乡镇(苏木)草地植物群落营养成分含量差异及特点。[结果] 各乡镇(苏木)中乌里雅斯太镇在公因子分析中提取的信息资料较少,植物群落养分中酸性洗涤纤维含量在公因子分析中提取的信息资料较少;萨麦苏木、嘎海乐苏木和道特淖尔镇草地植物群落中性洗涤纤维含量高达70%以上,额吉淖尔镇和阿拉坦合力苏木草地植物群落粗蛋白含量高于10%,呼热图淖尔苏木草地植物群落粗灰分含量较高,达到10.53%;东乌珠穆沁旗草原植物群落由西向东粗蛋白含量呈下降的变化趋势,酸性洗涤纤维和中性洗涤纤维含量呈上升的变化趋势。[结论] 该研究采用对应分析方法揭示了东乌珠穆沁旗草原植物群落营养成分由西到东的变化趋势,阐释了各乡镇(苏木)草地植物群落草地营养成分含量的变化规律。

Abstract: [Objective] To define the current situation of nutritional components of grassland plant communities in East Ujimqin Banner of Inner Mongolia, to promote the sustainable development of grassland animal husbandry, and to improve the grassland ecological environment. [Method] The grassland plant communities of 10 towns in East Ujimqin Banner had been taken as the research objects in this study. The nutrient contents of the grassland plant communities were analyzed, and the differences and features of nutrient contents among grassland plant communities in different towns were characterized combining with corresponding analysis method. [Result] Minor information was extracted from common factor analysis in Uliyastai Town among the investigated towns, and the information of acid detergent fiber content in nutrients of grassland plant communities extracted from common factor analysis was also limited. The content of neutral detergent fiber was higher than 70% in the grassland plant communities of Samai Town, Gahaile Town and Daotenaoer Town; the content of crude protein was higher than 10% in the grassland plant communities of Ejinaoer Town and Alatanheli Town; the content of crude ash in the grassland plant communities of Huretunaoer Town was 10.53%; the crude protein content of the grassland plant communities in East Ujimqin Banner was decreased from west to east, while the contents of acid detergent fiber and neutral detergent fiber showed an increasing trend. [Conclusion] The variation trend of nutritional components of grassland plant community in East Ujimqin Banner from west to east is revealed by using correspondence analysis method, and the changing law of nutrient contents of the grassland plant communities in towns of East Ujimqin Banner is characterized.
