巴厘岛植物园是用于研究活动、环境教育/服务和娱乐的迁地植物保护。然而，这一地点成为周围贝杜古尔盆地地区发展的磁石。然而，这是一个孤立的地区，空间利用有限。土地利用/土地覆盖变化随陆地卫星时间序列(1997和2014)的变化可以弄清楚这如何影响其周围的土地保护和转换。研究方法采用数字图像处理、地理信息系统和野外测量/观测相结合的方法。利用有监督的多光谱分类方法提取土地利用/土地覆盖信息。利用归一化植被指数(NDVI)进行植被密度分类。对样点进行现场测量，采用有目的的抽样方法。它作为绿化带和绿色屏障，既保护了上游的生态系统，又控制了下游的土地变化。上游自然区保护较好(94%保持不变，5%消失，植被盖度增加1%)，但下部地区与建成区相比变化了25.46%。
Bali Botanical Garden is the ex-situ plant conservation which has been used for research activities, environment education/ services and recreation. However, this site becomes a magnet of regional development in the surrounding Bedugul Basin. However, this is an isolated region which has limited spatial utilization. Land-use/ land Cover change with Landsat time series (1997 and 2014) can be figured out how this influences land conservation and conversion around it. The research method used digital image processing, GIS and field measurement/observation. Land-use/ Land Cover information was derived by supervised multispectral classification. NDVI analysis was used to classify the vegetation density. Field measurement made on the sample locations were selected based on purposive sampling method. It is as the green belt and green barrier which not only protecting the ecosystem in the upper but also controlling land changes in downstream. The natural region in this upperstream has well protected (94% constant, 5% lost and 1% increase of the vegetation cover) but this under area has changed by 25.46% as built areas.
