摘要

红树林是一种非常有价值的森林，但尽管有其好处，红树林仍因人类活动而不断退化。本研究的目的是绘制红树林的分布图，并根据NDVI植被指数值和环境质量分析红树林的健康状况。通过处理2020年的哨兵2-A卫星图像和实地测量，获得了红树林健康状况的分布情况。采用普通克里格法对水温、盐度、pH值和基质质地等物理参数进行处理，得到了红树林的环境质量。Taman Hutan Raya Ngurah Rai红树林的健康状况以健康类别的红树林为主。当靠近海岸和河岸时，红树林的健康状况会恶化。条件好的红树林植被往往具有最佳的环境质量条件，反之亦然。

Spatial Analysis of Health and Physical Parameters of the Mangrove Forest at Taman Hutan Raya Ngurah Rai, Bali Using Sentinel-2A

Mangrove forest is a very valuable forest, but despite its benefits mangrove forest continue to be degraded due to human activities. The purpose of this study was to map the distribution and to analyze mangrove forests’ health based on the NDVI vegetation index value and environmental quality. Distribution of mangrove forest health was obtained through the processing of sentinel 2-A satellite imagery in 2020 and field measurements. The environmental quality of the mangrove forest was obtained by processing the physical parameters which are water temperature, water salinity, water pH, and substrate texture using the Ordinary Kriging method. The health of the mangrove forest of Taman Hutan Raya Ngurah Rai is dominated by healthy category mangroves. The health of the mangrove forest worsens when closer to the shore and riverbanks. Mangrove vegetation with good conditions tends to have optimal environmental quality conditions and vice versa.
