- Abstract:
-
Water plays an important role in the ecosystem of sandy land, and it is an indispensable medium for the circulation of matter and energy in soil, plants and atmosphere. Therefore, the study on the change law of soil water in sandy land and its influencing factors is of great significance to reveal the stability of the ecosystem of sandy land and to clarify the process of hydrological change in sandy land. From sandy soil moisture changes in time and space, water infiltration characteristics and water balance research expounded the sandy soil water dynamic characteristics, research status and analyzed the spatial and temporal variations of soil moisture and its impact factors, revealed the different levels of soil moisture change rules of time and space, changes of soil moisture in different rainfall conditions and different artificial vegetation zone in the response of the amount of soil water infiltration under different rainfall conditions, summarized the research progress of sand soil moisture model, discussed the research of sand soil moisture model's relationship with environmental factors. Based on the review of the research progress on soil moisture in sandy land, the following researches should be strengthened in the future.(1)To study the relationship between plant function type and soil water amount in mixed forests with different afforestation modes in sandy land, and to find out the threshold value of artificial vegetation on soil water use in different periods.(2)To establish the model relation of transformation from point to plane scale to better quantify regional water bearing capacity under large scale.(3)To Systematically study the water balance, water transfer process and transformation law of the soil-vegetation-atmosphere system and establish the coupling model;(4)To explore how to improve the productivity of vegetation by improving the soil fertility of sandy land in the limited water resources environment.
