【摘要】：近年来,由于水土流失和草原退化程度加剧,草原生态系统抗灾能力变弱,在全球气候变化影响下,雪灾、旱灾等自然灾害频繁发生,这些潜在的威胁严重制约着草原畜牧业以及牧区经济社会的健康发展。本文以牧户饲草料储备量变化为视角,以锡林浩特市和苏尼特右旗两地区50多户面对面实地访谈数据为基础,以面板数据回归分析法等计量分析法分析了近些年饲草料储备量和其它变量的关系,深入阐明了饲草料在草原畜牧业生产中发挥的重要影响和作用机制,例如：冬季饲草、饲料储备量与牧户总收入、净收入及出栏畜产品收入的关系；冬季饲草、饲料储备量对12月基础母羊平均重量及绵羊羔成活率的影响；12月基础母羊平均重量与牧户生产效率的关系。研究结果表明：调研地区牧户冬季饲草、料储备量逐年上升,且饲料相对于饲草对牧户总收入和净收入增加的影响更加显著；牧户饲草料总量和单位羊日均饲草料量对12月基础母羊平均重量存在显著影响,且主要影响来自于饲草量而不是饲料量的供给；12月基础母羊平均重量增加使绵羊羔成活率上升,而使大绵羊死亡率呈现显著下降趋势；绵羊羔出栏平均毛重及出栏收入随12月基础母羊平均重量上升而提高,进而使牧户畜牧业总收入和净收入呈上升趋势。本文研究结果进一步证实了饲草料是草原畜牧业进行生产经营的物质基础和保障,对实现规模化、集约化、现代化和可持续的草原畜牧业发展产生重要影响,在草原畜牧业转变现代化生产方式、防御冬夏自然灾害、提高牲畜质量等方面都起到十分显著的促进作用。而且饲草和饲料对牧户增强抗灾能力的作用有较大的区别,所以本文建议进一步结合舍饲和放牧方式,系统分析在高风险条件下牧户的可持续经营模式。
[Abstract]:In recent years, due to the increasing degree of soil erosion and grassland degradation, the resilience of grassland ecosystems to disasters has become weaker. Under the influence of global climate change, natural disasters such as snow disasters, drought and other natural disasters occur frequently. These potential threats have seriously restricted the healthy development of grassland animal husbandry and the economic and social development of pastoral areas. Based on the face-to-face interview data of more than 50 households in Xilinhot and Sunita right Banner, the relationship between forage reserves and other variables in recent years was analyzed by panel data regression analysis and other econometric methods. In this paper, the important influence and mechanism of forage in grassland animal husbandry are expounded, for example, the relationship between forage stock in winter and total income, net income and income of livestock products, forage in winter, forage in winter, forage in winter, forage in winter, forage in winter, The effect of feed reserve on the average weight and survival rate of lambs in December and the relationship between the average weight of basic ewe and the productivity of herdsmen in December were studied. The results showed that the forage stock increased year by year in winter. The effect of forage on the total income and net income of herdsmen was more significant than that of forage, and the total forage amount and the average daily forage amount per sheep had a significant effect on the average weight of the basic ewe in December. In December, the average weight of ewe increased the survival rate of lambs increased, but the mortality rate of large sheep decreased significantly. The average gross weight and income of lambs increased with the increase of the average weight of the basic ewe in December. Therefore, the gross income and net income of pastoral animal husbandry are on the rise. The results of this study further confirm that forage is the material basis and guarantee for grassland animal husbandry to carry out production and management. Modernization and sustainable development of grassland animal husbandry have an important impact on the transformation of grassland animal husbandry into modern production methods and the prevention of natural disasters in winter and summer. The improvement of livestock quality has played a very significant role in promoting livestock quality, and there is a great difference between forage and fodder in enhancing the ability of pastoral households to resist disasters. Therefore, this paper suggests to further combine the methods of house feeding and grazing. This paper systematically analyzes the sustainable management model of herdsmen under high risk conditions.
