Influence on the surrounding vegetation’s spatiotemporal changes by Jinping II Hydropower Station

Abstract

Abstract The Jinping II Hydropower Station, located near Jinping Mountain, is a strategically significant hydropower project. The construction and operation of this project have impacted the surrounding ecological environment. The Normalized Difference Vegetation Index (NDVI) is widely used in remote sensing and serves as a crucial parameter for assessing vegetation health and ecological vitality. Through quantitative analysis using Sen’s slope and the Mann-Kendall non-parametric test on NDVI, we gained a deeper understanding of the impact of hydropower station construction on the surrounding vegetation. The primary objective of this study was to systematically investigate the spatiotemporal variations in NDVI before, during, and after the construction of the Jinping II Hydropower Station. The research findings contribute to the formulation of strategies aimed at mitigating potential adverse effects on the environment while promoting the region’s sustainable development goals.
