摘　　要：目的探讨主成分分析在农村环境卫生质量综合评价中的应用,为各级政府、有关部门制定改善农村环境卫生的对策提供科学依据。方法于2011年7~8月通过分层随机抽样选取福建省19个县1 900户家庭,用全国统一的调查表收集资料并用主成分分析法对资料进行综合评价。结果提取的3个主成分累计方差贡献率达到了87.14%,包含了农村环境卫生11项评价指标的全部信息。3个主成分依次反映了农村户厕、病媒生物、集中式供水的卫生状况。从主成分综合得分的排序情况来看闽南沿海经济发达地区环境卫生质量优于闽北经济欠发达地区,区域经济发展不平衡是制约我省农村环境卫生发展的主要原因。结论理论和实践表明主成分分析法是客观地综合评价农村环境卫生质量的一种简便、易行的方法。Objective To explore the application of principal component analysis method in evaluation of the rural environmental health quality,so as to provide the scientific basis for government at all levels and the department concerned in making countermeasures for improving rural environmental health quality. Methods Stratified random sampling method was used to select 1 900 rural households in 19 counties of Fujian province during July-August,2011,the national unified questionnaire was used to collect data and principal component analysis was performed to comprehensively evaluate the survey data. Results The cumulative variance contribution rate of the extracted 3principal factors which contained all the information of 11 evaluation indexes of the rural environmental health was 87.14%.The 3principal factors in turn reflected the sanitation status of the rural household latrine,the vector and the centralized water supply.From the composite score scheduling of the principal component,the rural environmental health quality of the economically developed coastal areas in southern Fujian province was better than the economic low-developed areas in northern Fujian province.The imbalance of regional economic development was an important cause in restricting the development of Fujian’s rural environmental health. Conclusion Practice and theory show that principal component analysis is a simple and convenient method for comprehensive evaluation of the rural environmental health quality.
