长江流域水土保持科学研究进展及展望

Scientific Research of Water and Soil Conservation in the Yangtze River Basin:Retrospect and Prospect

自20世纪80年代以来,长江流域水土保持科学研究取得了重要进展,为了解流域水土流失现状、制定水土保持政策与规划及实施水土保持防治提供了科学依据。当前,我国正处于推进生态文明建设的关键时期,系统总结长江流域水土保持科学研究发展历程、基础理论重点与亮点及水土保持关键技术、科研平台建设等取得的成果。但总体来看,长江流域水土保持科学研究还比较薄弱,理论研究还落后于水土保持实践。通过明确今后的研究重点,即土壤侵蚀动力学机制及其过程、水土保持措施防蚀机理及其适用性、退化生态系统的修复机理及其技术研发、重大生态治理工程生态过程及其效应评价,对于加强科技创新,推进流域水土保持事业发展具有重要意义。

Since the 1980s,notable progress has been made in scientific research of water and soil conservation in the Yangtze River Basin,providing scientific evidence to understanding the current situation of soil erosion in the basin,formulating soil and water conservation policy and planning,and implementing soil and water conservation.At present,China is in the crucial period of promoting the construction of ecological civilization.In view of this,we sum up the development process of soil and water conservation research,the key points and highlights of basic theory and key technology,as well as the construction of scientific research platform in the Yangtze River Basin.But overall,the scientific research foundation of soil and water conservation in the Yangtze River Basin is still relatively weak,the theoretical research still lags behind the practice of soil and water conservation.By clarifying future research priorities,that is,the dynamic mechanism and process of soil erosion,erosion prevention mechanism and applicability of soil and water conservation measures,restoration mechanism and technology research and development of degraded ecosystem,ecological process and effectiveness evaluation of major ecological treatment projects,our research would be of great significance to strengthening science and technology innovation and promoting the development of soil and water conservation in the Yangtze River Basin.
