草畜平衡管理系列研究(2)——对现行草地载畜量计算方法的剖析和评价

Series studies of animal demanding-feed availability balance control(2)——Evaluation on current method of animal carrying capacity calculation

通过对现行草地适宜载畜量推算方法的实例分析,对以此为基础的草地载畜量计算方法进行了评述,对现行方法中所设置的一些参数的合理性和必要性进行了剖析。本研究认为,随时间推移,草地畜牧业的生产方式有很大改变,现行载畜量计算方法在理念上比较落伍,在参数选择上存在缺陷,已经不能适应现阶段的草畜平衡管理需求。

In this study, the current technical guidelines for animal carrying capacity calculation methods were evaluated through field analysis of animal carrying capacity. Some of technical parameters in the technical guidelines were evaluated on their suitability and necessity in the estimation procedure. It was considered that the current method was out of date in the approach of selecting parameters as the mode and methods of animal production have been changed dramatically. Some parameters were obviously unnecessary and should be disregarded or modified in accordance with animal production system in grassland regions practically.
