MATHEMATICS ECOLOGY MODELING METHOD OF NATURAL LAKES ECOSYSTEM INLAND WATERS IN IRAN

Simulation is usually applied to study different subject’s especially ecologic matters but that is very important that most of ecologic matters are qualitative. If we want to study them, it is essential that these qualitative subjects be verified to quantitative subjects. There are some kinds of methods for changing the qualitative matters but mathematic method is as important methods. Computer programs can always compile graph or solve the mathematic matters by software. Some environmental specialized soft wares include Mathematic, MAPLE, and MATLAB and also different languages of programing can help us for this case. So we find the relation between FORTURN and R in solving ecologic matters. All indicators are seen based on their relations and also in time function in mathematic model. So modelling application is more extensive than this subject that ecologic relation can be stated mathematical method. Therefore, if we want to use mathematic model for energy relation in different indicators of this lake, we can state this matter as follows it is suggested that mathematic and figuring models evaluate inland watery ecosystems. The future views of watery ecosystems and continuation of present process are studies by mathematic model. Ecologic matters and problems of natural lakes are studying modelling quantitatively that we can solve some of them. If it is necessary that incoming damages into watery ecosystems be studied, besides mathematic model, economic or ecologic- economic models can be applied.
