摘　　要：农户行为是农村水土流失产生的主体,也是水土流失治理和生态恢复的主体。通过参与式农户访谈法(PRA)对粤北岩溶山区典型农户进行调查,以调查结果为依据,分析其农户行为与水土流失的耦合关系。结果表明:(1)农户行为与水土流失原因及治理存在耦合关系;(2)土地利用不合理、坡耕地比重大与植被破坏等农户行为是水土流失的主因;(3)农户植树种草、梯田和耕作措施等行为利于水土流失的控制和治理,是粤北岩溶山区水土保持的主要措施。Farmers＇ behaviours are the main reasons for rural soil and water loss, and it aslo is the main meas- ures of soil and water conservation and ecological restoration. By meang of participatory farmer interview （PRA）, the household interview survey was conducted in the typical karst mountain area of Guangdong Province so as to analyze the coupling relationship between farmers＇ behaviours and soil and water loss. The survey results indicated that： （1） there was coupling relationship between farmers＇ behaviors and the reasons and control measures of soil and water loss; （2） farmers＇ behaviours such as unreasonable use of land, larger proportion of sloping land, and vegetation damage were the main causes of soil erosion; （3） farmers-planted trees and grass, terraces and tillage could help control and manage soil erosion, which can be taken as main measures of soil and water conservation in the north karst mountain area and should be promoted and devel- oped in this area.
