摘要
对植物群体逐年、逐季发生变化的这种动态形式──波动进行了论述,给出了根据草地贮草量的时间动态评价草原资源时间均衡性的指标──时间均衡指数,用以对草原生物量的季节均衡性、年均衡性等一些时间均衡性进行评价。
The dynamic form──wave motion that plant population change year by year and season by season was discussed.On the basis of time dynamic of amount of grassland storing,the index of grassland resources time balance was evaluated,and the index of time balance was given to evaluate some time balances such as the season balance and the year balance of grassland biomass.
