Abstract
An approach to the remote determination of the character of bioproduction processes in aquatic phytocenoses is proposed. The investigated plant communities can be used as natural bioplato for the elimination of biosafety threats to water consumption. The relevance of these studies is determined by the increased need for expanding the arsenal of methods for remote diagnosis of the states of natural systems that are important for biosafety provision. In particular – to ensure biosafety when using natural feed resources by waterfowls, which are a potential reservoir of bird flu. The similarity in the dynamics of the colorimetric parameters of phytocenoses and the Margalef’s succession model makes it possible to implement a new approach to the generation of productive working hypotheses for the development of remote methods for determining the state of bioproduction processes in natural bioplato. The proposed approach is based on the use of the class of mathematical models, which is called the discrete models of dynamic systems. Based on the structure of the correlations between the colorimetric components of space photographs of the plavni in the mouth of the river Danube, a description of the structure of the intercomponent and intracomponent relations of the massifs of semi-submerged higher aquatic plants has been obtained. The resulting structure of intercomponent relations allowed us to construct idealized trajectories reflecting the dynamic changes of the system. A unique constant inverse relationship between the parameter reflecting the amount of green chlorophyll pigment affecting the level of photosynthetic production and the parameter reflecting the amount of orange-red pigments in each of the possible matrices of the ratios of colorimetric parameters has been revealed. As a result of analysis of the dynamic aspects of the RGB model, the structure of the system color parameter is shown, which is the mean square deviation of the spread in the degree of alignment of parameter values reflecting the amount of green and orange-red pigments. As a result of analysis of the systemic colorimetric parameter of photographs of the section of the Danube plavni during various periods of the vegetative season, it is shown that it is advisable to use it as a marker of the risk of secondary water pollution, which can be used for remote determination of the state of bioproduction processes in natural bioplato.
Highlights
The changeability of the world that the human lives in has been critically increasing
The o bjective of present work is to model colorimetric parameters of images of the semi-submerged higher aquatic plants (SSHAP) massifs in the breeding areas of waterfowls. This will make it possible to determine the structure of systemic colorimetric parameters (SCP), the changes in the ratios of which will signa l the impending change in the states of production of live a nd in the accumulation of dead biomass, leading to secon d ary water pollution
A working hypothesis based on Results of the processing of space photographs of the plavni the previously obtained results of modeling the structure at different periods of the vegetative season were compared of relations and dynamics of colorimetric parameters of with the corresponding states of bioproduction processes in cultivated plants crops using discrete modeling of dynamical systems (DMDS) was used to process SSHAP
Summary
The changeability of the world that the human lives in has been critically increasing. In the extreme situations in question, it is advisable to use remote (aerospace) methods to collect information on the nature of bioproduction processes This is determined, in particular, by the following two factors. There are a number of factors that make it extremely urgent to control and correct the state of bioproduction processes in natural plant communities These are global climate changes, critical level of human activity impact on nature, the high level of risks of technogenic disasters and even terrorist acts that create biosafety threats. The same applies to SSHAP massifs, which act as natural bioplato and reduce the risks of biosafety threats from different types of water consumption The scale of these risks makes the problem of expanding of the arsenal of high-tech science intensive methods of controlling of the nature bioproduction processes in plant communities quite urgent. These working hypotheses relate to the form of the original vegetative indices, their effectiveness is verified during processing of images of the SSHAP massifs
