AI Technical Summary
The lack of effective methods for estimating the carbon sequestration potential of soil phytoliths in Chinese fir forests in the current technology leads to insufficient accuracy and reliability in the assessment of carbon sequestration potential of Chinese fir forests.
By selecting sample plots within the distribution area of Chinese fir forests, and dividing the forest stands into early-stage forests, mid-stage forests, mature forests, and special regenerated forests according to their developmental stages, soil samples at different depths were collected using three-dimensional grid division and random sampling. Combined with phytolith extraction technology and multi-dimensional coupling analysis, a dynamic correlation model was constructed to quantify the dynamic correlation between carbon storage in Chinese fir forest phytoliths and core driving factors, and to extrapolate the scale of carbon sinks at different forest stand developmental stages.
This method improves the representativeness and uniformity of soil sample collection, ensures the accuracy of detection indicators, reduces errors caused by soil heterogeneity and environmental fluctuations, and provides a reliable method for assessing carbon sink resources in Chinese fir forest phytoliths, thus providing decision support for carbon sink accounting and forestry management.
