尉犁县草原监测和理论载畜量的测算报告

Calculation of Grassland Monitoring and Theoretical Stocking Capacity in Yuli

测算尉犁县2020年草原监测和理论载畜量,能为畜牧业可持续发展提供理论依据。经过高峰期调查,笔者计算了全县不同草地类型的草群高度、植被盖度、牧草产量,并得出2020年全县理论载畜量。尉犁县天然草原牧草平均高度为51.80 cm,植被盖度为33.80%,每100 m^(2)植物种数种3〜5种,平均鲜草产量1017.83 kg/hm^(2)。全县2020年鲜草总产量为130676.98万k g,理论载畜量为358019只羊单位。对比2016-2020年5年的数据,草群高度、植被盖度、产量均有不同程度的增加。

Calculating grassland monitoring and theretical stocking capacity in Yuli in 2020,provide a theoretical basis for the sustain-able development of animal husbandry.After peak survey,calculated the grass height,vegetation coverage,and forage yield of dfferent grassland types in the county,and get the county's theoretical stocking capacity in 2020.The average height of natural grassland in Yuli is 51.80 cm,vegetation coverage is 33.80%,several species of plants per 100 square meters 3~5 speces,the average fresh grass yield per hectare is 1017.83 kg.Through the comparison between 2016 and 2020 in 5 years,the height of grass goup,vegetation coverage,and yield all showed dfferent degrees of increase,the county's tolal fresh grass output in 2020 is 130676.98 kg.and the theoretical stocking capacity is 358019 sheep units.
