为掌握新疆哈密草原牧草生长趋势,开展了哈密草原区返青期的定点监测,并与上一年度结果进行了比较分析。结果表明,巴里坤县牧草整体返青时间比去年推迟5 d以上;伊州区返青时间较上一年推迟约10 d左右,与常年相比也推迟了5～7 d左右;伊吾县天然草原牧草50%返青期较上一年推迟了约5d左右。观测结果为当地天然草地季节性放牧管理和草畜平衡制度实施提供科学依据。
Abstract：In order to know well the growth trend of grassland in Kumul prefecture, fixed-point monitoring for the returning green period of grassland was carried out, and the monitoring results were compared with the previous year. The results showed that the overall time of grass returning to green in Balikun county was delayed by more than 5 days than that of last year; that of Yizhou district was about 10 days later than that of last year, and it was also delayed by about 5 to 7 days compared with normal years; the time of grass returning to green in 50% natural grassland of Yiwu county was delayed by about 5 days compared with the previous year. In conclusion, the research results would provide scientific basis for seasonal grazing management and for the implementation of grass-livestock balance system.
