Danube Rivers Morphology and Revitalization - DANUBEPARKS

V. GUIDE OF MANAGEMENT MEASURESIn this report we present a guide managemnt measures to achieve a balanceof functions (production, habitat for plant and animal species, regulation and control,information) and structure (species, associations, communities) of actual ecosystemsthrough work of revitalisation in the Danube Floodplain.In practice, the beneficiaries of these sensitive areas like the DanubeFllodplain have difficulties regarding the management of the areas, especially inagricultural and fishery polders, which were created for specific purposes altering /deteriorating the balance of the individual components of the system. Thus manysuch areas are often unused because of fragmentation of the energy flow betweencomponents of the socio-ecological.complex.The first activity from the guide (Figure 11) is the primary decision-makingunit on the existing system by standardized qualitative and quantitative assessmentsof ecosystem functions and their structure.This includes the general characteristics of the observation unit, particularly onthe basic functions of ecosystems. As is well known, productivity and stability ofecosystems is in direct relation with their support ability to provide physical supportfor the use of natural resources and provide socio-economic services.Analysis of ecosystems as dynamic systems, nonlinear and as productiveunits, is a long term proccess whose variability and diversity are essential fo rthestability and productivity of the unit.This analyse not leave out the social and economical implications of wearingaway of natural capital takes into account also socio-economical systems followingthe same principles.The coherent understanding and the interpretation of complexity and dynamics ofspatial-temporal interactions between human population and nature is possiblethrough interdisciplinary integration in a frame theoretical model which permit theidentification/ understanding of evolutional and adaptable transformations. From thisview, could be admitted an unforeseeable component of dynamic of ecologicalsystems. The theoretical arrangement regarding the character of functional andstructural modifications is produced by 4 key- issue (Holling &Gunderson 2002):1. Structural band functional modifications in ecological systems aren'tcontinuously and gradually and even prevalent chaotic. They have an episodiccharacter, with slow accumulation periods (for example physical structures,89
