摘      要：Shrub expansion into arctic and alpine tundra is one of the prominent vegetation changes currently *** studied the expansion of shrub vegetation into high elevation tundra in the Kvarkush Range of the Northern Ural mountains,*** structure analysis of the dominant shrub Juniperus sibirica *** to support ongoing upslope advance of shrubs,a process particularly active in the second half of the 20 th *** found a close connection between the expansion of shrub vegetation and the general change in climatic conditions of the cold season(months with mean airtemperature below 0°Сfrom November to March).In general,the greatest influence on the distribution of *** is exerted by the climate conditions of the beginning(November-January)and the end(March)of the cold *** increasing elevation,the correlation coefficients between the establishment of *** shrubs and the precipitation of the beginning of the cold season increased,and reached maximum values at the top elevation level of the study ***,the upwards shift of *** into typical mountain tundra does not lead to changes in the ecological structure of vegetation at this stage,but simply a decrease in the area of mountain tundra.
