The national-scale continuous maps of arithmetic mean height and weighted mean height across China address the challenges of accurately estimating forest stand mean height using a tree-based approach. These maps produced in this study provide critical datasets for forest sustainable management in China, including climate change mitigation (e.g., terrestrial carbon estimation), forest ecosystem assessment, and forest inventory practices.

Short summary
To quantify forest carbon stock and its future potential accurately, we generated a 30 m resolution forest age map for China in 2020 using multisource remote sensing datasets based on machine learning and time series analysis approaches. Validation with independent field samples indicated that the mapped forest age had an R2 of 0.51--0.63. Nationally, the average forest age is 56.1 years (standard deviation of 32.7 years).

Short summary
Short summary
We propose a method that integrates fuzzy set theory and a weighted Bayesian model to evaluate the hazard probability of land subsidence based on Interferometric Synthetic Aperture Radar technology. The proposed model can represent the uncertainty and ambiguity in the evaluation process, and results can be compared to traditional qualitative methods.

Short summary
This study produced the first sub-meter map of Spartina alterniflora in mainland China for 2020. Compared to the 10 m product, the sub-meter map achieved a 14.60% increase in overall accuracy, revealed a 57.73% discrepancy in spatial distribution, and detected 17 times more individual patches. The improved sensitivity to small patches significantly enhances early detection of Spartina alterniflora invasion. This finer mapping further refines soil carbon estimates and informs wetland management.
