偶然发现

The results showed:①the communities that stipa baicalensis is edificator had the highest species diversity, and the idea that stipa baicalensis communities were the local zone vegetation was supported;②the majority of studied communities were unsaturated in the species diversity, and the species diversity had a tendency to increate with the improvement of soil environment;③the relation of species diversity to community productivity was a one-humped function, that is, the species diversity of mediation productivity was highest;④the species diversity under intermediate disturbance was highest, and the intermediate disturbance hypothesis was supported;⑤the content of potassium in soil had probably an important function, or was an important following factor in the types of grassland community;⑥a new hypothesis on the forming mechanism of species diversity of community, Small Scale Competition and Random-Patch Dynamic Hypothesis, was put forward boldly.

通过上述研究分析得出如下结果：①以贝加尔针茅为建群种的群落物种多样性最高，从物种多样性角度证明该群落类型最适应本区气候和环境条件，应是本区的地带性群落；②绝大多数群落的物种多样性处于未饱和状态，随土壤环境的改善呈明显的增加趋势；③物种多样性与群落生产力呈单峰函数关系，即在中等生产力水平时物种多样性最高；④放牧中等干扰水平物种多样性最高，支持Connell的中度干扰学说；⑤偶然发现土壤钾含量可能在草地植被类型分化中起到重要作用，至少是一个重要的伴随因子；⑥大胆提出了群落物种多样性构成机制的新学说即小尺度竞争随机斑块动态学说。
