Introduction. 
It is the duty of today's 
generation to keep the productivity of pasture lands 
at a high level and pass it on to the next generation. 
Here, pasture plants productivity are very 
important, as well as to correctly determine their 
main species, class, distribution and coverage area 
and the degree of their consumption by livestock. 
Almost all available pastures in Ahangaran district 
of Tashkent region are natural pastures, which have 
not been cultivated for the last 30 years. Therefore, 
it is important to analyze the changes in its main 
climatic indicators in order to select a set of works 
aimed at the management and improvement of 
pasture lands.
Relevance of the topic.
It is well-known 
fact that, in the last 25-30 years,35-40% of pastures 
and hayfields have been degraded, the number of 
plants type have decreased by 20%, and pasture 
yields have fallen by 1.5-2 times. Ahangaran 
district of Tashkent region consists 6 massifs: 
Uzbekistan, S.Rakhimov, Angren, Ahangaran, 
A.Navoi, Almalyk and Dustlik massifs and other 
areas, where total area of pastures is 84,725 ha, and 
the total degraded area is 18,115 ha, which is more 
than 21% of the total hectares. The most degraded 
area is found in pastures of Uzbekistan, and A. 
Navoi massifs of the district. Livestock grazing 
on pastures in the district is carried out mainly in 
spring, summer and autumn.
From these data it can be seen that despite 
the fact that Ahangaran district is located in the 
most favorable climatic conditions of the country, 
21% of its pasture lands have been degraded over 
the past 25-30 years. To prevent such negative 
consequences, it is mostly important to study the 
caused factors. As mentioned above, the pastures 
of Ahangaran district are natural pastures, and the 
cultivation of pastures in its territory has not been 
carried out for the last 30 years. It can be seen 
that one of the main reasons for the continuing 
loss of productivity of pastures in the district is 
the ongoing changes in the climate of the district. 
Therefore, the analysis of changes in the climatic 
indicators of Ahangaran district over 30 years
