Summary: Hydrological regimes and climatic factors have complex influences on plant phenology in floodplain wetlands. Warmer temperature tends to advance the start of the pre-flooding growing season, while flood regimes play a dominant role in determining the phenology in the post-flooding growing season. Carex phenology is more affected by hydrology in high-elevation areas compared to low-elevation areas. These findings provide insights for the conservation and management of floodplain wetlands in the Yangtze River.

Summary: This study compares the performance of seven climate models in estimating GPP in China and finds that BCC-CSM2-MR and MPI-ESM1-2-HR provide the best estimations at both regional and national scales. However, no model can capture the interannual variation of GPP well, and all models produce excessive precipitation over the Tibetan Plateau, which affects the ecosystem. Improving the modelling of the Plateau climate and ecosystem-climate feedbacks is urgent.

Summary: Soil erosion is a global soil degradation problem that endangers land, freshwater, and oceans. Rainfall erosivity has led to an increase in soil erosion rate worldwide, while vegetation restoration serves as a protective measure against soil erosion. Therefore, studying the impact of precipitation and vegetation on the spatial distribution of soil erosion is crucial for understanding the erosion mechanism. Based on the RUSLE model, a global soil erosion dataset from 2000 to 2015 (0.25 degrees x 0.25 degrees) was created to assess the extent of global soil erosion. The data revealed that soil erosion was on the rise in 70.80% of the study area, with precipitation being the predominant factor. Spatially, erosion was mainly concentrated in Asia and North America, with Asia experiencing a decreasing trend in erosion during the study period. Results also showed that erosion primarily occurred in the temperate zone, accounting for 39.97% of the area. Precipitation and vegetation significantly increased in 24.43% and 16.74% of the regions, respectively. However, in 29.12% and 53.81% of the regions, precipitation and vegetation had a negative impact on erosion. These findings contribute to a deeper understanding of the erosion mechanism.

Summary: China has the largest distribution of carbonate karst in the world, with the southwest region centered in Guizhou being a critical ecological security barrier. Scientific diagnosis of the health and sustainability of karst ecosystems is essential for ecological restoration and sustainable development. In this paper, the evolution and development of karst landforms are summarized, along with five aspects related to the calculation of weathering and soil formation rate, diagnosis of soil water, evaluation of soil and water loss, interpretation and evolution of rocky desertification, and measurement of ecosystem services. The methods and models for diagnosing the health of karst ecosystems must be improved and innovated to accurately depict the response process of karst ecosystems to climate change and human activities.

Summary: This study investigated the migration regulation of Cd during soil formation and erosion in karst areas. The results demonstrate that soil Cd concentration and bioavailability are both significantly higher in alluvium compared with those in eluvium. The Cd isotopic fingerprint revealed that the active Cd in the alluvium of the study profile was probably derived from the corrosion of carbonate rocks rather than by eluviation of the eluvium. The corrosion of carbonate rocks is a substantial natural Cd source and poses significant potential risks to the ecological environment.

Summary: Karst ecosystems are crucial for billions of people, and accurately diagnosing and evaluating their health is necessary for socioeconomic development. However, current evaluation methods have limitations, particularly in considering the impact of soil formation rate on ecosystem health. A new index was established to represent the actual health status of karst ecosystems, revealing that the soil formation rate threatens the health of 28% of global karst ecosystems, covering an area of 594 km2. A dataset of karst ecosystem health index values from 2000 to 2014 was created, showing that 75.91% of the areas were unhealthy. This study emphasizes the contribution of soil formation rate to karst ecosystem health and provides a new method for accurate evaluation, enhancing future research and management.
