Provide a model system for the analysis of urban green space and water Shiraz Municipality

Reducing the country's water reserves is a problem that has its effects in various areas, such as climate, agriculture, vegetation, and so on, and an analysis of this dilemma is also an issue that needs to be analyzed in different ways. In this paper, using a systematic approach to the dynamics of the system, the dynamic relationship between municipal water and urban green space in Shiraz will be considered as one of the major cities of Iran. The system model of this study was simulated and analyzed using the above-mentioned approach and with DSS Vensim software. The analytical results of the research indicate that, if the water consumption is continued in accordance with the current situation, in the near future we will see the completion of municipal water. In this regard, the sensitivity analysis and the presentation of different scenarios of this problem were examined. The results of simulation and modeling indicate that thermal islands and construction are one of the most important factors affecting the increase of water. Also, the most important factors affecting water loss, type and rate of water use in the Shiraz municipality are vegetation cover. In this regard, the quantitative results of the model show that if water consumption per square meter can be reduced by 40 percent, 242 million cubic meters of total water will be saved in the 30-year period of simulation.
