摘要

南榜省卡连达街道的人口每年都在不断增加。人口的增加意味着对生活空间的需求也在增加,这可能导致土地覆盖从植被区转变为住宅区。为了找出一年的土地利用变化有多大,需要对18年的空间分析。因此,它有望能够管理空间规划,以应对印度尼西亚的灾害。本研究使用了使用归一化植被指数(NDVI)方法计算的Landsat 7和8图像。结果表明:2010 - 2019年,开放土地/房屋/建筑物/无植被的土地覆盖变化增加了814 ha(6.9%),低植被的土地覆盖变化增加了975 ha(8.4%)。而在中游,植被减少约1123 ha(9.5%)。地面检查的总体观测样本遵循了卡连达街道土地覆盖的实际情况。数据表明,在卡连达街道,土地管理是必要的,以抑制土地覆被变化,使其不会导致环境灾害

VEGETATION CHANGES ANALYSIS USING NDVI (NORMALIZED DIFFERENCE VEGETATION INDEX) METHOD IN KALIANDA SUBDISTRICT, LAMPUNG SELATAN DISTRICT, INDONESIA
Each year, the population in Kalianda subdistrict, Lampung province keeps increasing. The increase in population means that the need for living space also increasing, this can lead to land cover conversion from a vegetation area to a residential area. To find how much the change in land conversion over the year, a spatial analysis over the period of 18 years was needed. So that it is expected to be able to manage spatial planning to cope with disasters in Indonesia.  This research uses Landsat 7 and 8 images that have been calculated using the Normalized Difference Vegetation Index (NDVI) method. The results show that between 2010 - 2019, there is an increase in land cover changes in open land/house/building/no vegetation around 814 ha (6.9%), in low vegetation increase 975 ha (8.4%). However, in the medium vegetation was decreasing around 1123 ha (9.5%). Overall observation sample of the ground check is following the actual condition of land cover in Kalianda Sub-district. The data show that in the Kalianda subdistrict, land management is necessary to suppress land cover changes so that it won’t lead to environmental disasters
