Based on thoroughly review of the past 70 years development of soil and water conservation in China, the authors outlined the methodical advance that from qualitation to quantitation and the progress of framework that from incompleteness to more perfect, and then summarized the three stages of regionalization of soil and water conservation’s evolution. Statistical analyses were employed to determine to what extent these regionalizations have influenced soil and water conservation both theoretically and practically. Moreover, three main problems of the existing regionalization schemes were proposed which are absence of economics and management science, flaws of indicator system and lack of implementation, and their corresponding solutions were raised by scenario simulation and case study. Considering the trend of regionalization, two topics, the balance between quantitative and qualitative studies and the more attention paid on practice, were discussed in the end with the hope that it could present some inspired thoughts for further development of regionalization.
