ABSTRACT
The biological quality of an environment is defined as the condition reflecting thequantitative representation of living organisms in a given space and time. My lecturepresents how to qualify the environment of a biocenosis synbiologically, in other words, onthe supraindividual level. In this case, qualifying the environment in practice means thatboth the quantitative and qualitative composition of the biocenosis, and also the factorsresponsible for their distribution in space and time are considered and evaluated ascharacteristics. The ultimate goal of examining conditions is to evaluate, in other words, todetermine relevancy and significance in a given biocenosis. We are facing the problem thatin Hungary at present the biological survey methods are not standardized, and they arehighly varied. An environmental information system however cannot function beforeappropriate methods of biological survey are created. The lack of such methods wouldresult that one of the three major, organically complementary sources of information (i.e.the abiotic sphere, the biosphere, and human society) is completely missing. From adifferent aspect, ecological survey studies are different from the rest of environmentalsurvey studies, inasmuch as they study living organisms and their communities, thusinevitably utilizing the results of other environmental survey studies that evaluate differentcomponents. This indicates that the ecological section of all environmental survey studies isvitally important due to its complexity, and should be considered primarily decisive.
