Assessment of the initial development of forest park zones created in urbanized areas

Abstract

The article is devoted to the development of methods for assessing the state of initial development of forest park zones created in suburban areas. The purpose of the research is to consider the possibility of introducing a multiplicative indicator that equally takes into account these indicators, to study its extreme characteristics for homogeneous and heterogeneous land plots. The relationship between factor C from the universal equation of soil losses and the weight of dry biomass of deciduous trees which, in turn, are regression dependent on NDVI (Normalized difference vegetation index), a numerical indicator of the quality and quantity of woody vegetation on the site, is considered. Two criteria are proposed to assess the initial state of development of the urban forest park zone. It is shown that the first criterion has a minimum at a certain NDVI value. The second criterion is presented in the form of a functional containing the function of the relationship between NDVI and factor C. It is determined that the extreme of this functional has the form of a function of the inverse relationship between NDVI and factor C. The real existence of such an inverse relationship between NDVI and C opens up new opportunities for using this function in metrology.
