察布查尔锡伯自治县不同类型草原三年载畜量的变化及经济效益分析

Three Years’ Change of Stocking Capacity of Different Types of Grasslands near Chabuchar and its Economic Benefit Analysis

2018年至2020年,连续3年对察布查尔锡伯自治县内的7个草地类型进行野外地面调查,结合室内分析,对7个类型的草原的地上生物量、载畜量和产生的经济效益进行分析,探讨不同草地的合理载畜量及经济价值,为实现草畜平衡提供技术支撑。结果表明:察布查尔锡伯自治县内7个类型草原的合理载畜量差异大,温性草甸草原的载畜量最大,承载力最强,温性荒漠类草地的载畜量最小,承载力最弱。温性荒漠类草地的经济效益低但生态价值大。建议通过发展人工草地进行土地置换,提高土地的载畜量,既发展了畜牧业又保护了草原生态。

From 2018 to 2020,the three year’s field investigation of the seven types of grasslands near Chabuchar were analyzed, and the aboveground biomass, stocking capacity and economic benefits were analyzed in the laboratory, the reasonable stocking capacity and economic value of different types of grasslands were discussed, to provide technological knowledge for the balance of livestock.The results showed that: there was a great difference in the reasonable carrying capacity of the seven types of grasslands near Chabuchar, the reasonable carrying capacity of the temperate meadow grassland was the largest, and the bearing capacity was the strongest, the reasonable carrying capacity of the temperate desert was the smallest, and the bearing capacity was the weakest.The economic benefit of temperate desert grassland was low and its ecological value was high, suggested that develop artificial grassland for land replacement, increase the carrying capacity of land, which not only develop animal husbandry but also protect grassland ecology.
