Environmental impact assessment is a tool to ensure the proper and correct implementation of a project, and it can be considered as a way to determine, predict and interpret the effects of a proposed project on the environment. In the process of assessing the effects of the environment, human judgments have always been effective in making decisions and with choosing the type of use or measuring the impact of developments on the environment.  In the present study, the environmental effects of Khurshid Park have been investigated through the rapid impact assessment matrix (RIAM). The matrices have been scored by experts in this field and their results have been presented through Pastakia model formulas in the form of a range of quantitative and qualitative changes. The result is that the negative effects of the project in the construction and exploitation phases are especially evident on the biological environment, so the implementation of environmental management and monitoring program is necessary for the project, and if there is the decrease in theof negative effects of the project in the construction phase and given the positive effects of the project in the eExploitation phase, the project is feasible and will have positive and beneficial effects in the short and long term onin the region. At the end of the research, environmental observation suggestions and solutions are presented to reduce the negative effects of Khurshid Mountain Park Mountain.
