定性调查是监测评价农业和农村开发项目的重要信息来源之一。对项目参加者和其它主要信息提供者进行定性调查,有助于了解项目复杂的生态、社会、文化和其它方面的情况。也能帮助正确地判断项目人口的观点、态度和行为规律,而这是其它信息收集方法所不及的。而且,可以运用定性调查来编制假设和计划,而后运用结构调查方法,在更广泛的人口范围内检验这些假设和计划的实用性。监测评价工作人员至今尚未充分认识到定性调查的潜能。其中,大多数人接受过农业经济或统计的培训,更熟悉定量信息收集与分析的程序,但尚未接触 Qualitative surveys are one of the important sources of information for monitoring and evaluating agricultural and rural development projects. A qualitative survey of project participants and other key informants helps to understand the complex ecological, social, cultural and other aspects of the project. It also helps to correctly judge the opinions, attitudes and behaviors of the project population, something that other information collection methods can not do. Moreover, qualitative assumptions can be used to prepare assumptions and plans, and structural surveys can then be used to test the utility of these assumptions and plans in a broader population. To date, monitoring and evaluation staff have not fully recognized the potential of qualitative research. Among them, most people have been trained in agricultural economics or statistics and are more familiar with the procedures for quantitative information collection and analysis but have not yet contacted them
