Major Achievements and Future Key Fields of Soil Erosion Research in China
[Objective] The developing history of soil erosion research in China was reviewed
the major research achievements were summarized
and the current problems and key research fields in the future were analyzed to provide a reference for China's soil and water conservation
regional ecological construction
and high-quality green development.[Methods] Based on years of work experiences from field investigations and academic research on soil erosion
long-term consideration has been given to major issues related to soil erosion in China through numerous academic discussions and communications with leading experts.[Results] A series of major research achievements have been obtained in the field of soil erosion in China during the last one hundred years
but there have also some drawbacks and problems. In the future
soil erosion research in China should focus on several key fields
such as the improvement
promotion
and accuracy evaluation of soil erosion prediction models; calculation methods and model construction for slope runoff; evaluation of the representativeness and validity of results from simulated rainfall and flume scouring experiments; and so on. More attention should be given to the mechanisms of soil erosion processes
model applications
technical methods
response evaluations
bottleneck problems
and other issues.[Conclusion] Researches over the past century has shown that soil erosion research should be conducted based on national conditions. Symbolic achievements could only be achieved by determining and adjusting research directions according to the characteristics of soil erosion
the research status
and the changes in social demands in China. Meanwhile
in the new era when the country is vigorously promoting the construction of ecological civilization
soil erosion research must be refreshed with new ideas and emphases. Moreover
soil and water conservation practices should also be integrated with rural revitalization and ecological construction by giving priority to soil erosion prevention and reducing disturbance to soil. Besides
we should change the previously used model of instituting laws and regulations after soil destruction and water loss occurred.
