对短花针茅荒漠草原轮牧和连续放牧下重点植物种群的生殖特征进行了比较研究。结果表明，轮牧比连续放牧产生更多的生殖头和更多的种子。轮牧有利于重要植物幼苗的成活和生长，但效果不如围牧。营养繁殖比受降水影响的种子繁殖更流行。
The comparative study on the reproductive feature of key plant populations under rotational grazing and continuous grazing was conducted in Stipa breviflora desert steppe.The results showed that more reproductive heads and more seeds were produced in rotational grazing than in continuous grazing. It was benefit to survival and growth of seedling of key plants in rotational grazing, but not effective as in exclosure. The vegetative propagation was more popular than seed reproduction that was affected by precipitation.
