A spatial model of sustainable green open space planning in Bandar Lampung City, Lampung Province

摘要

Urban physical development is currently experiencing rapid growth and evolvement; this is marked by an increase in population, with all its activities in the struggle over city space. The impact of this development is a reduction of urban green open space (GOS). This research was conducted in Bandar Lampung City. This study aims to identify changes in land use, analyse the need for green open space, develop a GOS planning model and estimate the need for GOS in the city of Bandar Lampung in the future. The spatial analysis method with guided classification was used. Furthermore, logistic regression statistical analysis and carbon emission analysis were conducted. The highest land use variables consist of slope, village, built space, road and population. The level of CO2 emission is 87362.702 Gg in Bandar Lampung City. The required GOS area in 2024 is 1503.637 ha. Planning for GOS in the coming years must be able to provide the GOS needs of the citizens of Bandar Lampung City, maintaining the sustainability of GOS through GOS spatial modelling.
