目的 了解武警部队官兵对野战应急便携式厕所的使用需求。方法 选择来源于3个武警总队的4个支队，每个支队随机抽取7个中队。采用观察法、问卷调查、个人访谈法收集野战厕所使用需求和野战厕所设计的未来预期等相关数据。结果 共调查官兵1789名，回收有效问卷1711份(95.64%)。所调查的支队中有2个没有配备野战应急厕所;另2个支队中各有3个中队配备有简易的制式野战厕所。92.63%的被调查官兵执行过野外任务，每年执行5次及以上有129名(7.54%)。1411名(82.46%)没有用过便携式厕所。对便携式厕所的需求程度打分，最高10分，有241名(14.1%);最少1分，98名(5.7%);平均(7.58±2.17)分，得分最多的是7分，有491名(28.7%)。结论 部队执行野外任务多，而部队配置便携式厕所少，官兵对其需求强烈。

Objective To study the soldiers' needs of using emergency portable toilet in field conditions. Methods Four branches from three corps and seven detachments were chosen from each branch. Questionnaire survey and personal interview were employed to collect data of requirements and expectations for emergency portable toilet. Results 1789 soldiers were recruited for the survey and 1711 (95.64%) valid questionnaires were recovered. As a result, two branches did not have a field emergency toilet. Each of the other two branches had three detachments, which were equipped with a simple emergency portable toilet. 92.63% of the soldiers investigated had carried out field missions; of them 129 (7.54%) soldiers did 5 times or more in a year. 1411 (82.46%) soldiers had not used portable toilet. Scoring on the demand for portable toilets, 241 (14.1%) soldiers chose the maximum 10 points. And 98(5.7%) soldiers chose the minimum 1 point. The average score was (7.58±2.17)points and the most frequent score was 7 points which were chosen by 491 (28.7%) persons. Conclusions Troops performed field missions frequently, while so few places were equipped with emergency portable toilet. So the needs of using emergency portable toilet are strong.
