Water equivalent method for city phytostructure of Indonesia
This paper proposed a simple method and rapid to carry out for organizing city phytostructure. Carbon dioxide sequestration was addressed and referred to population number instead of city area. The unit storage of carbon dioxide, which was nothing less than greenspace area, was determined using equivalent method of determining unit storage of water. For various population number (P) of city area in Indonesia, the greenspace unit (GU) was 29P-0.3 – 3.2, and the greenspace area (GA) was 29P0.7-3.2P. Greenspace distribution was preferably on wetlands, river lines, top ground level, and north south direction.
