Abstract: | The relevance of this work is that the analysis of time series of satellite data allows for the remote assessment of urban vegetation productivity, identification of its general trend, and establishment of factors influencing plants. The value of such data is obvious for an independent assessment of the effectiveness of urban greening programs, the impact of pollution, and the timely identification of disturbed areas. The objective of this work is to identify patterns of long-term dynamics of urban vegetation productivity using the example of Abakan, located in the semiarid conditions of the Republic of Khakassia, based on ground-based meteorological information and Terra MODIS satellite data. As a result of the work, it was concluded that in the semiarid conditions of Khakassia, the amount of heat received has a strong effect on urban vegetation. In the period from 2000 to 2023, based on the basic growth rate, a weak positive trend of NPP and GPP (8-15.2%) was established. The novelty of the study is that new Terra Modis data on the long-term dynamics of productivity and evapotranspiration of urban vegetation in Abakan from 2019 to 2023 were analyzed. |
