Abstract:Typhoons have a profound influence on reshaping the fabric and functionality of terrestrial ecosystems within the expansive landscapes of China, especially the southeastern coast, where their disruption to coastal vegetation is notably pronounced. This study aims to unravel the intricate effects of typhoons on vegetation and delve into the responses within China's coastal zones. Employing MODIS Enhanced Vegetation Index (EVI) and Leaf Area Index (LAI), we aim to explore vegetation resilience when facing varying typhoon categories and to elucidate the intricate dynamics of post-typhoon recovery spanning nearly two decades from 2001 to 2019. Over these 19 years, a total of 70 typhoons made landfall in the southeast coastal area of China. This formidable meteorological phenomenon, categorized as typhoons (TY), strong typhoons (STY), and super typhoons (SuperTY), numbered 35, 26, and 9, respectively. Taiwan was found to be the region most frequently impacted, weathering an impressive 26 typhoon landings, closely followed by Guangdong with 20. The net change rates in EVI and LAI follow the landfall of these various typhoon categories. Intriguingly, after Typhoon landfalls, the Enhanced Vegetation Index exhibited a net change rate of 4.88%. However, the story took a different turn with strong and super typhoons, resulting in net change rates of -7.48% and -1.85%, respectively. The patterns were even more pronounced in the leaf area index, where typhoons demonstrated a net change rate of 22.28%, while strong typhoons and super typhoons showed -65.70% and -17.60%, respectively. The aftermath of these typhoons unfolded a narrative of post-typhoon recovery dynamics. Across the entire study area, the majority of vegetation along the southeastern coast exhibited a remarkable capacity for restoration within a mere three months of the typhoon disturbance. However, within this broader trend, regional disparities were evident. Zhejiang and Guangdong provinces displayed lengthier recovery periods compared to their counterparts. On the other hand, the provinces of Hainan and Taiwan experienced relatively swift vegetation restoration. The implications of this study stretch far beyond the realms of scientific inquiry, shedding light on forest management and ecosystem conservation in China's coastal regions. By providing a detailed understanding of the intricate patterns of vegetation response to typhoons, these findings form a solid foundation for informed decision-making in the face of natural disturbances. They contribute significantly to the overarching goal of enhancing the resilience and sustainability of China's coastal ecosystems, underscoring the imperative of a proactive and adaptive approach to the challenges posed by these powerful meteorological events.
