- Abstract:
-
To analyze community diversity, stability and the their correlation, community diversity and stability within and out of fence in the same community and the three community diversity and stability within and out of fence in QingHai lake area were measured and compared according to three diversity indexes: the Simpson index, the Shannon-Wiener index, and the Pielou index as well as a community stability index: the improved M-Godron method. The result shows that: (1) the diversity of fence alpine meadow is greater than enclosure, the stability is on the contrary; the diversity of enclosure steppe is greater than fence, the stability is on the contrary; the diversity of enclosure temperate steppe is greater than fence, the stability is on the contrary; (2) by comparing the diversity out of fence, the rank of diversities is the alpine meadow > steppe > temperate, by comparing the stability out of fence, the level of stability is in the order of the steppe > temperate > alpine meadow; (3) by comparing the diversity within fence, the rank of the diversities is the alpine meadow > steppe > temperate, by comparing the stability within fence, the level of stability is in the order of the temperate steppe > steppe > alpine meadow. There is an obvious negative correlation between diversity and stability in alpine meadow, alpine steppe and temperate steppe.
