【 摘 要 】

Denpasar as the provincial capital of Bali still has 2225 rice fields. Denpasar Regional Spatial Plan (SP) 2011-2031, paddy fields as Green Open Space (GOS) 1563 ha. GOS is intended for the preservation of agrarian culture, the balance of urban ecosystems, and agro-ecotourism. Preservation of resources and economic improvement of the area needs to be developed a data base of sustainable food agriculture land (SFAL) planning. SFAL from the results of spatial analysis of 10 thematic maps defined as GOS, the Subak region's spatial data base from analysis of satellite images, and subak attribute data from the results of agroecosystem land suitability classification. Information on Subak resource potential using QGIS software version 2.18.0 through join attributes. SFAL/GOS paddy fields for SP years 2031-2050 = 1064.14 ha (47.83%), for SP more than 2050 = 695.09 ha (31.25%) from 2015 paddy fields. Paddy fields in North Denpasar and East Denpasar ± 80 % as SFAL/GOS, South Denpasar and West Denpasar 0%. Land suitability for lowland rice is 100% very suitable (S1), production increase is done through efforts to improve the availability of irrigation water and phosphor fertilization. Horticultural crops 80% potentially developed, with improved drainage, water availability and fertilization.
