Article Synopsis
- Regional land use changes significantly affect carbon storage in ecosystems, particularly in the source region of the Yellow River, highlighting the importance of predicting these impacts for sustainable development.
- From 2000 to 2020, carbon storage in the area increased by 11.59 million tons, mainly due to the expansion of wetlands and shifts in grassland coverage.
- Projections for 2040 indicate further carbon storage increases, with the natural change scenario showing a rise of 3.92 million tons and the ecological protection scenario yielding an even larger increase of 13.53 million tons, underscoring the need for informed land use management.
Article Synopsis
- * The optimized 3PG model showed significantly improved accuracy in GPP estimation with an R value of 0.948 and a lower root mean square error (RMSE) compared to the original model, which had an R value of 0.854 and higher RMSE.
- * Sensitivity analysis revealed that GPP estimation uncertainty was most influenced by temperature, followed by factors such as the enhanced vegetation index and photosynthetically active radiation, highlighting their importance in model accuracy.

Forest leaf area index (LAI) is an important indicator to describe the forest canopy structure and growth status of trees. In this paper, the Yigen area of Inner Mongolia was selected as the study area. Taken full account of the differences among different echo types, the LiDAR point cloud data were split into different single lasers.

Objective: To determine the reliability and validity of the Duke Social Support Index (DSSI)-23 scale in a rural elderly population.
Methods: A stratified cluster random sampling strategy was adopted to select 702 rural participants aged 60 years or over in Guangyuan. Those with severe hearing disorders or mental problems were excluded.
