PROGRESS AND PROSPECT OF COUPLING RESEARCH ON AGRICULTURAL WATER AND SOIL RESOURCES
This research aims to find research hotspots on the coupling of agricultural water and soil resources,sort out the development process of research,coordinate and summarize the research system,clarify the future research development direction and breakthrough points,and assist in the sustainable use of agricultural water and soil resources.The research method combined qualitative and quantitative research,a preliminary analysis was conducted on the research hotspots and development process of agricultural soil and water resources coupling from 1992 to 2022 by using CiteSpace software.Subsequently,the research system was further summarized by using literature induction method.The results were listed as follows.The research focused on the efficiency and effectiveness of agricultural water and soil resources utilization,and went through a development process from soil physical and chemical properties to optimal allocation of water and soil resources,from small-scale crop planting to large-scale watershed management.The research system consisted of three research fundamentals and six research basic points,including the matching pattern of water and soil resources,the process of water and soil resource utilization,and the response of water and soil resource status,namely,the coupling research system of agricultural water and soil resources based on"pattern-process-response".Therefore,in terms of the matching pattern of water and soil resources,it is necessary to further clarify the spatial differentiation characteristics of water and soil resources,and strengthen the research on the physical interaction process and spatiotemporal variation laws of the two.It is recommended to focus on identifying the differences in water and soil resources allocation and establishing practical matching grading standards in the future;The research on the response of hydrological processes to land use changes in the process of water and soil resource utilization needs to be supplemented.It is suggested that in the future,the binary mutual feedback mechanism between land use and hydrological processes can be further explored;In terms of response to climate change,attention should be paid to exploring the relationship between soil and water resources in agricultural production from meteorological indicators.It is recommended to strengthen dynamic monitoring and prediction simulation of inefficient utilization issues in the context of climate change in the future.
