摘要
分析了甘肃省肃南县天然草地的垂直分布与水平分布特征、不同草地类型的生产力差异及不同季节天然草地的利用率,测算了退化草地理论载畜量和等级的变化幅度,划分了不同草地的退化类型及其在不同区域的分布规律。
The characteristics of horizontal and vertical distribution of natural grassland, the production capacity differences of different types of degraded grassland and utilization rate of natural grassland were analyzed. The changing range of the theoretic carry capacity and the grade of degraded grassland were calculated. The different types of degraded grassland were classified and the distribution law in different regions was introduced.
