社会研究中的参与性绘图的特点是方法多元化，两种常见的方法是使用利益攸关方访谈的定性绘图和通过数字互联网绘图利用更大的公共样本的定量方法。迄今为止，还没有系统地评估参与性测绘中的混合方法在多大程度上适用于相同的研究环境和研究问题而产生有效的结果。为确定澳大利亚金伯利地区的海洋和沿海价值，在一个大型研究项目中实施了混合方法研究设计(探索性、序贯性和汇聚性并行)。完成了与利益相关者的定性访谈(n=167)，以使用多边形成图法和基于互联网的公众参与地理信息系统(PPGIS)方法(n=578)确定基于地点的值。我们定义并实施了并行、相称和收敛有效性的概念，以评估混合方法的研究结果。我们发现，在评估地点价值在研究领域的重要性时，定性和定量方法导致了中等到高的同时效度。收敛效度(空间)随地点值而变化很大，与地图美学、休闲捕鱼、旅游、生物多样性和土著文化价值的收敛效度较强，与生存、治疗和商业捕鱼价值的收敛效度最弱。通过使用不同的几何特征(多边形与点)来绘制大范围研究区域的值，收敛有效性受到弱公度有效性的影响。在收敛的平行设计中，混合方法用于规划决策支持的效用取决于在结构意义、空间位置和抽样总体中的值的一致性方面证明的收敛。(C)2016爱思唯尔有限公司。保留所有权利。
Participatory mapping in social research is characterized by methodological pluralism, with two common methods being qualitative mapping using stakeholder interviews and quantitative methods that engage larger public samples through digital, internet mapping. To date, there has been no systematic evaluation of the extent to which mixed methods in participatory mapping yield valid results when applied to the same research setting and research questions. A mixed methods research design (combined exploratory sequential and convergent parallel) was implemented in a large research project to identify marine and coastal values in the Kimberley region of Australia. Qualitative interviews (n = 167) were completed with stakeholders to identify place-based values using polygon mapping methods and internet-based public participation GIS-(PPGIS) methods (n = 578). We defined and operationalized the concepts of concurrent, commensurate, and convergent validity to assess mixed methods research outcomes. We found that qualitative and quantitative methods resulted in moderate to high concurrent validity when assessing the importance of place values in the study area. Convergent validity (spatial) was highly variable by place value, with stronger convergent validity found with mapped aesthetic, recreational fishing, tourism, biodiversity, and Aboriginal culture values, and weakest with existence, therapeutic, and commercial fishing values. Convergent validity was influenced by weak commensurate validity through the use of different geometric features (polygons versus points) for mapping values across a large study area. The utility of mixed methods for planning decision support in a convergent parallel design depends on demonstrating convergence in construct meaning, spatial location, and consistency in values in the sampling populations.
