近十年土壤侵蚀与水土保持研究进展与展望

在当今生态文明背景下,土壤侵蚀与水土保持研究迎来了新的发展机遇和挑战。本文首先采用文献计量学方法,定量分析了近10年来国内外土壤侵蚀与水土保持学科发展现状。在此基础上,结合社会需求的变化,阐明了学科发展需求与存在问题。最后,提出了本学科研究的重点领域与方向:水文过程与侵蚀产沙机理,土壤侵蚀过程及其定量模拟,全球变化下土壤侵蚀演变及其灾变机理,社会经济系统—水土流失的互馈过程,以生态功能提升为主的土壤侵蚀防治,以及土壤侵蚀研究新技术与新方法等。

Study on soil erosion and conservation in the past 10 years: Progress and prospects

Under the background of ecological civilization, soil erosion and conservation face new opportunities and challenges nowadays. We employed a bibliometric analysis on the research of soil erosion and conservation in the past ten years. The results summarized the research tendency and hotspots, and presented China''s main achievements and international status in this field. Considering social needs, we pointed out the main existing problems for scientific researches on soil erosion and conservation. Then, we identified the front scientific issues, including the coupling mechanisms of hydrology and soil erosion, the soil erosion process and modeling, the soil erosion evolution and its catastrophic mechanism under global change, the mutual feedback between socio-economy and soil erosion, the soil conservation for ecological function improvement, and the new technologies and methods for soil erosion research.
