水土保持措施适宜性评价的理论与方法初探

Primary Investigation on the Theory and Method of the Suitability Assessment on the Soil and Water Conservation Measures

在系统总结国内外水土保持措施适宜性研究成果的基础上,深入分析了水土保持措施适宜性评价的现实需求、理论发展与不足之处;基于水土保持学、土壤学、生态学、土地利用学和经济学等方面的理论与实践,提出了水土保持措施适宜性评价理论内涵、评价体系与方法、评价过程和工作流程;并建议在以小流域为单元的基础上,结合实际加强不同类型区、多尺度水土保持措施适宜性特征、评价指标的研究。

The practical demands, theory development and shortages in the field of the suitability of soil and water conservation measures were analyzed based on the summary of pertinent literatures. According to the theory and practice of the science of soil and water conservation, soil science, ecology, land use and econom- ics, the intension, assessment system, method and process were put forward in this study. It was suggested that the characteristic and indicator to evaluate the suitability of soil and water conservation measures should be strengthened in the different regionalization and multi-scale by taking small watershed as a unit.
