Abstract: Accurately predicting grass yield and livestock carrying capacity of grassland is essential for the sustainable development of herbivorous animal husbandry. It can effectively regulate the grazing quantity and quality,protect grassland,and help improve livestock performance. The domestic and foreign prediction models and accuracy for estimating grassland yield and stocking rate were summarized in this review. In addition,the advantages and disadvantages of various models were analyzed,and major problems existed in grassland management and the direction of future efforts were presented as well. We aimed to provide references for grassland conservation and utilization,and provide better ideas for the sustainable management of grassland resources in China.

Key words: Grassland production, Stocking rate, Livestock carrying capacity, Prediction models

摘要: 准确预测草地产草量和动物承载力是实现草食畜牧业可持续发展的必要条件,有效调控放牧的数量和质量,能够在保护草地资源的前提下,提高牲畜的生产性能。本文对国内外预测草地产草量的方法、预测精度、载畜率等方面的研究状况进行综述,分析了不同预测模型的优缺点,提出草地管理技术的主要问题以及今后需要努力的方向。以期为草地的保护和利用提供依据和参考,为我国草地资源的可持续管理提供思路。
