论文摘要
印度是2000年后全球绿化的第二高贡献者。有了卫星数据，我们在这里表明，由于限制变暖，在2001 - 2019年期间，叶面积指数（LAI）的增长18.51％未能转化为增加的碳吸收。我们的分析进一步显示，尽管LAI增加了6.75％，但2001 - 2019年期间，2001 - 2019年期间净初级生产力（NPP）降低了6.19％。我们确定了在印度东北部，印度半岛和西高止山脉的主要森林地区，NPP趋势上统计学上显着下降的趋势的热点。这些地区共同占印度NPP的31％（1274.8 TGC.YEAR -1）。这些地区是印度的变暖热点。降低光合作用和稳定的呼吸（高于阈值温度）是NPP下降的关键原因。变暖已经开始影响印度森林中的碳吸收，并呼吁在变暖世界中改善气候韧性森林管理实践。
India is the second-highest contributor to the post-2000 global greening. With satellite data, here we show that this 18.51% increase in Leaf Area Index (LAI) during 2001-2019 fails to translate into increased carbon uptake due to warming constraints. Our analysis further shows 6.19% decrease in Net Primary Productivity (NPP) during 2001-2019 over the temporally consistent forests in India despite 6.75% increase in LAI. We identify hotspots of statistically significant decreasing trends in NPP over the key forested regions of Northeast India, Peninsular India, and the Western Ghats. Together, these areas contribute to 31% of the NPP of India (1274.8 TgC.year -1). These regions are the warming hotspots in India. Decreasing photosynthesis and stable respiration, above a threshold temperature, are the key reasons behind the declining NPP. Warming has already started affecting carbon uptake in Indian forests and calls for improved climate resilient forest management practices in a warming world.
