Analysis of the dynamics of changes in landscape ecological structure using geographic information system (GIS) technology in Badung regency, Bali

The development of land use in Badung Regency in the period 2013-2021 has an impact on changes in the ecological structure of the landscape. Changes in the ecological structure of the landscape occur in the three parameters, namely patch, matrix and corridor, which are indicated by changes in the area and function of the three parameters. The addition of matrix area in the settlement land use class and golf course patches causes changes in the area of the matrix of mixed gardens, rice fields and mangroves as well as corridors of non-volcanic coastal sand that dominantly have ecological functions. The objectives to be achieved in this study are to analyze the dynamics of changes in the ecological structure of the landscape caused by land use development in Badung Regency. The dynamics of changes in the ecological structure of the landscape due to large-scale changes is a driving factor in the deviation of spatial utilization and a decrease in the quality of the environment in Badung Regency. The research concluded that landscape ecology analysis is an important aspect in the development of regional zones in Badung Regency that takes into account the principles of sustainable development. This research found a new formulation in the analysis of ecological zone development that integrates the landscape ecology approach with the spatial approach and regional approach. The ecological zones of Badung Regency are grouped into 4 (four), namely: very high ecological zone, high ecological zone, medium ecological zone and low ecological zone.
