王金亮导师团队学术论文在SCI二区期刊《Scientific reports》上线发表

2024年03月29日，以张艳可（云南师范大学地理学部地图学与地理信息系统专业2019级硕士研究生）为第一作者，王金亮教授为通讯作者所撰写的题为“Extreme drought along the tropic of cancer (Yunnan section) and its impact on vegetation”的学术论文在SCI二区期刊《Scientific reports》上线发表(https://doi.org/10.1038/s41598-024-58068-w).

极端天气事件的频繁发生是气候变化的未来前景之一，生态系统如何应对极端干旱对应对气候变化至关重要。以2009年至2010年间在北回归线（云南段）发生的极端干旱事件为案例研究，使用标准化降水蒸散指数分析了极端干旱对增强植被指数（EVI）、叶面积指数（LAI）和总初级生产力（GPP）的影响，并分析了极端干旱后植被恢复的情况。结果表明：（1）由于干旱和植被物候的累积影响，2010年3月至5月的植被生长受到了更严重的影响。（2）与EVI和LAI相比，GPP对干旱更敏感，可以准确指示干旱影响植被的区域。（3）在极端干旱事件后，70%的植被可以在3个月内恢复，而2.87%至6.57%的植被在6个月后仍未恢复。（4）耕地和草地表现出最强烈的响应，恢复时间较长，而林地和灌木地表现出较弱的响应和较短的恢复时间。这项研究为极端干旱对植被的影响提供了参考。

摘要：

The frequent occurrence of extreme weather events is one of the future prospects of climate change, and how ecosystems respond to extreme drought is crucial for response to climate change. Taking the extreme drought event in the Tropic of Cancer (Yunnan section) during 2009–2010 as a case study, used the standardized precipitation evapotranspiration index to analyse the impact of extreme drought on enhanced vegetation index (EVI), leaf area index (LAI) and gross primary productivity (GPP), and to analyzed the post extreme drought vegetation recovery status. The results indicate the following: (1) Due to the cumulative effects of drought and vegetation phenology, vegetation growth in the months of March to May in 2010 was more severely affected. (2) Compared to EVI and LAI, GPP is more sensitive to drought and can accurately indicate areas where drought has impacted vegetation. (3) Following an extreme drought event, 70% of the vegetation can recover within 3 months, while 2.87–6.57% of the vegetation will remain unrecovered after 6 months. (4) Cropland and grassland show the strongest response, with longer recovery times, while woodland and shrubland exhibit weaker responses and shorter recovery times. This study provides a reference for the effects of extreme drought on vegetation.
