According to the analysis of definition, meaning and character of water resources carrying capacity, the mostly influencing factors were studied and the evaluation index system was established.

The simulation model is developed by using the simulation technology of system analysis and taking the Weishan Lake and Luoma Lake water resources system as an example.

In this paper, system analysis method is applied, a model of optimal conjunctive operation of surface water and groundwater resources for Fuyang, Huaibei district is established.
