• Microtopography Affects the Diversity and Stability of Vegetation Communities by Regulating Soil Moisture (2025) · Water · cited 13× · doi

  pay closer attention to the impact of slope position on soil moisture, nutrients, and vegetation communities, - incorporate studies on microtopographic features such as convex and concave slopes, - establish long-term monitoring plots to collect continuous multi-year data, - consider potential factors such as land use

• Surface fractal heterogeneity under microtopography during flow regime transition (2026) · Frontiers in Ecology and Evolution · doi

  The lack of understanding of how microtopography and hydrodynamics interact to affect soil surface microstructure and fractal heterogeneity. The need for a quantitative understanding of the continuous dynamic responses of surface fractal heterogeneity along flow transitions triggered by microtopography and prolonged rainfall.

• The Spatiotemporal Characteristics and Driving Factors of Soil Degradation in the Black Soil Region of Northeast China (2024) · Agronomy · cited 14× · doi

  The mechanisms and driving factors behind soil degradation remain unclear. There is a need to investigate the variation patterns of significant soil quality indicators and their driving factors. The study aims to fill this gap by examining the historical and current characteristics of soil quality.

• Analysis of Soil Quality Characteristics and Driving Factors of Micro-Landforms in Loess Hilly Areas (2026) · Plants · doi

  the soil samples were collected from the 0-60 cm soil layer, excluding deeper soil horizons; this may lead to an underestimation of the role played by deep-rooted systems and water regulation processes - as this study involved a single-point temporal survey, it is challenging to reveal the dynamic evolution of soil quality over time during restoration processes - the classification of microtopographic types relied on field surveys and empirical judgment, lacking support from quantitative topographic indices
