摘要
干旱是一种自然灾害,对粮食作物生产、工业、住区和农业等几个重要部门的供水造成重大损失。气候变化经常导致农业用地干旱,并可能间接威胁生计和粮食安全。本研究旨在分析旱情在农业用地上的分布及其与自然条件的关系。基于归一化干旱指数(NDDI)算法的Landsat 8 OLI影像干旱遥感监测研究是将归一化植被指数(NDVI)和归一化水指数(NDWI)两个参数相结合的结果。研究结果表明:2018-2021年,苏卡umi县Palabuhanratu区农业用地干旱分布分为正常、轻度、中度、重度和极重度5个等级,其中极重度干旱类别在2021年为80.78 ha, 2018年为32.09 ha。最可能发生干旱的地区在帕拉布汉拉图区,即Jayanti村和Citepus村。
Distribution of Drought on Agricultural Land in Palabuhanratu District Sukabumi Regency
Drought is one of the natural disasters that causes substantial losses to food crop production, water supply in several important sectors such as industry, settlements, and agriculture. Climate change often causes drought on agricultural land and can indirectly threaten livelihoods and food security. This study aims to analyze the distribution of drought on agricultural land and examine the relationship between physical conditions. Drought monitoring study using remote sensing methods on Landsat 8 OLI imagery with the Normalized Difference Drought Index (NDDI) algorithm is the result of combining two parameters, namely the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI). The results of the study show the distribution of agricultural land drought in Palabuhanratu District, Sukabumi Regency during 2018-2021 with five classes (normal, mild, moderate, severe, and very severe), and a very severe drought category of 80.78 ha in 2021, followed by 2018 an area of 32.09 ha. The most potential drought areas are in Palabuhanratu District, namely Jayanti Village and Citepus Village.
