Forest Ecosystem Carbon Measurement Methods and Future Directions
Published 2024-01-01“…The forest ecosystem is a crucial component of terrestrial ecosystems,possessing the largest carbon reservoir on the Earth's surface.The fluctuations in its carbon stocks have a profound impact on the global carbon cycle.In the current context of a growing greenhouse effect and the rising occurrence of extreme climates,accurately estimating carbon stocks in the forest ecosystem and strengthening the construction monitoring system for its carbon stocks holds great significance for gaining an in-depth understanding of the global carbon cycle and predicting global climate change.Oriented toward strengthening the carbon sink function of forest ecosystems and achieving the dual carbon target, this paper systematically explained the mechanism of carbon sequestration in forest ecosystems.It analyzed and compared several mainstream methods of forest carbon estimation, proposing feasible strategies for building a forest carbon stock monitoring system in China.The aim is to provide a theoretical reference for the stable improvement of China's forest ecosystem carbon stock monitoring capacity and to provide scientific support for achieving the carbon peak and carbon neutrality in a timely manner.…”

Policy Considerations for Using Forests to Mitigate Carbon Dioxide Emissions
Published 2001-01-01“…We agree that these results increase our understanding of the global carbon cycle. At the same time, their relevance in the context of the international climate change negotiations is much more complicated than portrayed by newspapers such as the New York Times (“Role of Trees in Curbing Greenhouse Gases is Challenged”, May 24, 2001) and the Christian Science Monitor (“Trees No Savior for Global Warming”, May 25, 2001).…”

Spatial-temporal Evolution of the Normalized Difference Vegetation Index (NDVI) in the Huaihe River Basin from 1999 to 2018
Published 2023-01-01“…Vegetation is one of the main participants in the global carbon cycle and plays an important role in land surface water transport and energy transmission.Based on the normalized difference vegetation index (NDVI) of the Huaihe River Basin (HRB) from 1999 to 2018,the spatial-temporal evolution law of NDVI was studied on three time scales (month,quarter,and year) through the Mann-Kendall trend test and empirical orthogonal function (EOF) decomposition.The following findings are obtained.① Affected by crop maturity and different landforms,the multi-year average values of monthly NDVI in the HRB present an M-shaped distribution as a whole,and there are some differences in the mean value and variation range of NDVI in different sub-basins.② In the downstream area with more farmlands,the NDVI shows an insignificant downward trend in summer and winter,while in other three sub-basins of the river,the NDVI follows an upward trend in all seasons,especially in spring and autumn.③ The annual NDVI of the basin exhibits a significant upward trend,which is the same as the global greening trend.This also indicates that returning cropland back to forests and other soil and water conservation measures have achieved remarkable results in vegetation restoration and ecological protection in the basin for the past 20 years.④ The spatial distribution of NDVI modes in the HRB shows simultaneous increases or decreases overall,with a great difference existing between the western and eastern areas.Vegetation coverage gradually decreases from inland to coastal.These research results can provide a reference basis for understanding the vegetation restoration characteristics and protecting the ecological environment in the HRB.…”
