摘　　要：为预防棉纺织从业人员生产安全事件或职业病,利用投影寻踪研究棉纺织企业作业环境综合风险。通过对棉纺织企业作业环境特点及危害的实际调查,选取噪声、粉尘、微气候和照明等4个因素作为评价指标,构建棉纺织企业作业环境风险评估指标体系;采用投影寻踪和遗传算法确定指标的权重,建立棉纺织企业作业环境风险评估模型;用该模型综合评价中南地区某棉纺织企业生产车间作业环境风险。研究表明：该企业前纺车间属轻度危害作业,细纱车间属中度危害作业;用该方法能够实现多因素棉纺织作业环境风险评估。In order to prevent incidents and occupational disease in cotton textile enterprise,a projection pursuit model was built. Before building the model,by analyzing the hazards of the working environment in textile enterprises,four factors such as noise,dust,micro-climate and lighting were identified for the assessment. The effective temperature was used as a micro-climate evaluation index,a risk assessment system of textile enterprises was established. The index weight values were calculated by using the projection pursuit and genetic algorithm. An application of the model was made to assessment of risk in a certain cotton textile enterprise in China. The results show that the fore-spinning workshop is a slightly harmful working environment and the spinning workshop is a moderately harmful working environment.
