摘要

The inhabitants value urban green space (UGS), which is an essential part of urban environmental systems. GIS software and tools have demonstrated a significant contribution to the UGSs distribution studies. Assessing UGS characteristics, including their abundance, geographical distribution, physical features and social functions is crucial for both urban planning and public health. Using Geographical Information System (GIS), we carried out an evaluation and a mapping of UGS, with their typologies and characteristics, in Sousse city in Tunisia. A data processing and statistical analysis have been carried out on the different UGS, using new GIS web application, quantum GIS and RStudio program. The results highlighted an imbalance in Sousse city’s spatial UGS distribution. In terms of quantity, the city's south lacks UGS, whereas the east has more UGS but of lower quality. The tourism area in the city’s north is surrounded by average to good quality green areas. The lack of a greenway connecting the city's green areas to the coastal demonstrates a failure to address networking and relationships, which accounts for the discontinuity between the public UGS. Using this GIS data, decision-makers will evaluate and keep track of the UGS in Sousse, which will enhance the quality of life. Finally, we have proposed a master plan for public UGS based on four guidelines for a sustainable planning. Nonetheless, to improve the master plan proposed, future studies combining this geographic data with additional qualitative research should be done and involving decision makers in the initial stages of the approach development.
