Green Open Spaces (GOS) have a variety of ecosystem services of which can be utilized by society. This study aims are to identify GOS criteria for determining ecosystem services, to study the conditions and distributions of ecosystem service potentials of GOS in Urban Area of Yogyakarta (UAY), and optimize GOS in the perspective of ecosystem services. The research locations included GOS of UAY consisting of urban forests, city parks, riverbanks, and greenbelts, comprising of twelve research locations. The identification of the criteria for GOS was done using the expert judgement and pairwise comparison methods resulting in weight values. The data from the field and the assessment by experts were analyzed by means of scoring analysis to find out the level of ecosystem services in each research location and they were further descriptively and deductively analyzed by taking account of the area allotment and the available regulations to attain the conditions of GOS with optimal ecosystem services.The results of the study show that of the sixteen criteria under study, each plays a role in ecosystem services. The values of ecosystem services of GOS in UAY show different values for each type of GOS. In general, the types of urban forests have ecosystem services in the high category for the eleven ecosystem services, while city parks and riverbanks on the average have ecosystem service values in the moderate category, and greenbelts have ecosystem service values in the low category. Based on the results, optimalize GOS in UAY in the perspective of ecosystem services can be done by optimizing each criteria with the highest weight value adjusted to the allotment of each type of GOS. |
