Design of Natural Environment Modeling Management System based on meta-model

In this era of simulation, environmental models are considered as an important factors effecting the correctness of complex simulation result. These demand a new approach in modeling natural environment. This kind of method has been proposed based on meta-model, but it has not been implemented by the author, here NEMMS is designed to implement the modeling process of Natural Environment. At first the relationship between the meta-model and model was analyzed in detail, then the system frameworks of NEMMS were given, and the objects classes and meta-models were proposed, at last, NEMMS was implemented and an example was used to illustrate the correctness of NEMMS.
