Progress in Research on the Ecological Water Consumption Patterns and Carrying Capacity of Typical Vegetation in Sandy and Coarse Sandy Areas of the Yellow River Basin
The Yellow River serves as a vital ecological security barrier in China.The primary reason for the difficulty in managing the Yellow River Basin is the imbalance of water and sediment,which is mainly related to soil erosion issues in the upper and middle reaches,particularly in areas with a high content of sand and coarse sand.Since the implementation of significant measures such as converting farmland back to forests and grasslands in the 1990s,the management effects in these areas have been remarkable,with a noticeable increase in vegetation coverage and gradual improvement in the ecological environment.However,the situation of soil erosion remains severe,and the ecological environment remains fragile.During the management process,the relationship between vegetation and water has not been fully considered,leading to issues such as imbalanced proportions and excessive afforestation density in some areas.Artificial forest communities have begun to show signs of decline and deep soil drying.This paper,combining previous research and the authors'scientific experience,reviews the water consumption characteristics and vegetation patterns of typical vegetation in sandy and coarse sandy areas,discusses the current problems in these areas,and provides a theoretical basis for future research directions and methods.
