The impact of vegetation phenology changes on the relationship between climate and net primary productivity in Yunnan, China, under global warming

Frontiers in Plant Science, 2023
Climate influences net primary productivity (NPP) either directly or indirectly via phenology. Therefore, clarifying the indirect effects of climate on NPP through phenology is of utmost importance.

Quantifying and Mapping Human Appropriation of Net Primary Productivity in Qinghai Grasslands in China

Agriculture, 2022
Human appropriation of net primary productivity (HANPP) is an important indicator for assessing ecological sustainability. However, the spatiotemporal dynamics of HANPP in the Qinghai grasslands remain unclear.

Fire intensity impacts on post-fire temperate coniferous forest net primary productivity [PDF]

Biogeosciences, 2018
Fire is a dynamic ecological process in forests and impacts the carbon (C) cycle through direct combustion emissions, tree mortality, and by impairing the ability of surviving trees to sequester carbon.

Net primary productivity, upwelling and coastal currents in the Gulf of Ulloa, Baja California, México [PDF]

Ocean Science, 2012
The Gulf of Ulloa, a highly productive area off the western coast of the Baja California Peninsula, is examined for five successive years (2003–2007) by using satellite data and seasonal net primary productivity (NPP) estimates obtained from a vertical ...

Discussion on rapid evaluation method of large-scale land degradation in China [PDF]

E3S Web of Conferences, 2022
This paper discusses the effects of land degradation assessment based on the index of net primary productivity (NPP), rain use efficiency of vegetation (RUE) and relative rain use efficiency of vegetation(rRUE). The results show that the land degradation
