“…Based on the findings that the provision of PSOP is not defined in laws that govern the preparation of MZP, DMZP and NZP, gradual measures were proposed at the end of the study. For example, PSOP should be clearly defined as a special spatial category (Kayden, 2000;Shafer, 2009), which is not the same as PS and PSOP. PSOP should become a mandatory component of the land subdivision plan when preparing MZP, DMZP and NZP, so that all areas in these plans are divided into PS, PSOP and PrS areas.…”
