Impact of shrub encroachment on soil hydrological processes in grassland
摘要
Abstract
Shrub encroachment in grasslands has become a worldwide phenomenon in arid and semi-arid regions,and is currently a popular topic in ecological research.In this paper,we review the current ecological literature to explore the impact of shrub encroachment on soil hydrological processes in grasslands,specifically examining the global distribution of shrub encroachment and its effects on precipitation,soil moisture,infiltration,surface runoff,and evapotranspiration.Shrub encroachment occurs widely across various ecosystems and is significantly influenced by rainfall.Increased rainfall in arid areas generally inhibits shrub encroachment,whereas increased rainfall in humid areas promotes it.Shrub encroachment can enhance soil water infiltration,reduce surface runoff,alter evapotranspiration components,and decrease soil erosion in grassland ecosystems.Further research integrating new technologies and methods should explore the mechanisms by which rainfall patterns affect the hydrological processes of shrub encroachment in grassland ecosystems.Such work would provide a scientific basis for the effective management of shrub encroachment in grasslands,facilitating improvements in the overall functionality of grassland ecosystems.关键词
