摘要
为全面、准确掌握哈密市草原植被物候期的基本规律,及时获取草原动态变化信息,科学评价哈密草原资源与生态状况,应用地面样方和气侯资料,对新疆哈密市2015—2021年2 300多个样地,7 900多个样方天然草原资源返青率、草原植被长势、草原生产力等状况进行动态监测。结果表明:2016年平均返青率达26.21%与其他年相比返青较好,全市平均鲜草产量达462.66万t,平均盖度44.6%;与近7年同期相比,2015年为草原长势峰值,鲜草产量达666.71万t,载畜量达338.6万只。2021年来盛期草原生产力在逐步回升,草地的适宜载畜量增幅较为明显,载畜能力明显增强,与近年来实施大面积休牧、轮牧、禁牧等草原保护措施,及大力推行草畜平衡制度有关。
In order to comprehensively and accurately grasp the basic laws of the phenological period of the grassland vegetation in Hami City,timely obtain information on the dynamic changes of the grassland,scientifically evaluate the grassland resources and ecological conditions in Hami City,and use the surface sampling and climate data to dynamically monitor the natural grassland resource rejuvenation rate,grassland vegetation growth,grassland productivity and other conditions of more than 2300 sample plots and 7900 samples in Hami City,Xinjiang from 2015 to 2021.The results showed that the average green returning rate in 2016 was 26.21%,which was better than that in other years.The average fresh grass output in the city reached 4.6266 million tons,with an average coverage of 44.6%;Compared with the same period in recent 7 years,2015 was the peak of grassland growth,with fresh grass output reaching 6.6671 million tons and livestock carrying capacity reaching 3.386 million.,In the peak period since 2021,the grassland productivity is gradually rising,and the suitable livestock carrying capacity of the grassland has increased significantly.It is related to the implementation of grassland protection measures such as large-scale rest grazing,rotational grazing and grazing prohibition in recent years,and the vigorous implementation of the grass livestock balance system.
