Urbanization has accelerated the conversion of vegetated land to built-up regions. The purpose of this study was to evaluate the effects of urban park configuration on the Land Surface Temperature of the park and adjacent areas. In urban parks, the study analyzed the Normalized Difference Vegetation Index (NDVI), the Normalized Difference Built-up Index (NDBI), and the Land Surface Temperature (LST). The NDVI categorization process resulted in the development of a vegetation density distribution. The majority of Medan's urban areas were categorized as low density, as seen by their low NDVI values. The NDBI values were significantly higher in the majority of the area. This shows that the majority of places are experiencing a decline in vegetation cover. The density of vegetation varies according to the placement of park components such as trees, mixed plants, recreation, and sports areas. According to LST data, the temperature in the urban park was cooler than in the surrounding areas. Although the surrounding areas are densely populated, urban parks are dominated by trees. Additionally, there is a green space adjacent to the park, which is a green lane that runs alongside the main roadways.
城市化加速了植被土地向建成区的转化。本研究旨在评估城市公园布局对公园及周边地区地表温度的影响。在城市公园中,本研究分析了归一化差异植被指数(NDVI)、归一化差异建筑指数(NDBI)和地表温度(LST)。NDVI 分类过程产生了植被密度分布。雅加达市区的大部分地区被归类为低密度,这反映在它们较低的 NDVI 值上。在大多数地区,NDBI 值显著更高。这表明大多数地方的植被覆盖正在减少。植被密度根据公园组件的位置而变化,例如树木、混合植物、娱乐和运动区。根据 LST 数据,城市公园的温度比周边地区凉爽。尽管周边地区人口稠密,但城市公园以树木为主。此外,公园旁边还有一片绿地,这是一条沿着主要道路的绿色车道。
