A research entitled "Evaluation Of Green Open Space In Pontianak Kota Subdistrict, Pontianak City". The aims of this research is to describe the physical condition of green space and conduct an evaluation so that the minimum standard of public green space can be met and green space can fulfill the supporting functions of ecological, aesthetic, social, and cultural quality. This research uses a survey method by conducting observations and interviews in collecting primary and secondary data. Tools and equipment needed in conducting observations and interviews are questionnaires and cameras. Green open spaces consisting of City Parks and Green Lane Roads that are located in Pontianak Kota Subdistrict have a distribution of vegetation that is still small and poorly structured which causes a decrease in aesthetic value and lack of maintenance. The evaluation results show that there needs to be a realignment that must be done in every green open space contained in Pontianak Kota Subdistrict. Rearrangement can be done by adding the amount or replacing the type of vegetation and adding other facilities so that the main function of the green open space can be fulfilled.
