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.

GRASSLAND NPP MONITORING BASED ON MULTI-SOURCE REMOTE SENSING DATA FUSION [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Vegetation is an important part of the terrestrial ecosystem. It plays an important role in the energy and material exchange of the ground-atmosphere system and is a key part of the global carbon cycle process.Climate change has an important influence on

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.

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

Precipitation and soil nutrients determine the spatial variability of grassland productivity at large scales in China

Frontiers in Plant Science, 2022
Changes in net primary productivity (NPP) to global change have been studied, yet the relative impacts of global change on grassland productivity at large scales remain poorly understood.

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 ...

Asymmetric warming significantly affects net primary production, but not ecosystem carbon balances of forest and grassland ecosystems in northern China [PDF]

, 2015
We combine the process-based ecosystem model (Biome-BGC) with climate change-scenarios based on both RegCM3 model outputs and historic observed trends to quantify differential effects of symmetric and asymmetric warming on ecosystem net primary ...
