We collected potential risk factors using questionnaire, and conduced lung function using a portable pulmonary function instrument.Results: A total of 2963 participants were included in this analysis, of whom 1268 were males and 1695 were females. There were 504 participants with COPD, generating a prevalence of 17.01%. With the increase of age, the prevalence of COPD in different genders increased significantly. The results of different regions were χ2= 627.89, p < 0.01, indicating significant differences in the prevalence in different regions. Among them, based on the existing survey data, it is speculated that Shache county has the highest crude prevalence, but the sample size needs to be further expanded. The participants with high age, smoking, lower BMI, high waist circumference, systolic blood pressure, fried cooking and barbecue share more COPD than those who partake of fruits and vegetables in this study.Conclusion: The prevalence of COPD among the Uyghur population in the Kashi region is higher than the national rural average. Among them, high age, smoking, low BMI, high waist circumference, high systolic blood pressure, cooking methods that may be stir-fried and deep-fried barbecue are risk factors for COPD, and vegetable and fruit intake may be a protective factor for COPD.Keywords: Uyghur population, chronic obstructive pulmonary disease, prevalence, risk factors, epidemiology study

This paper proposes a new method for predicting the preliminary aging of MOA (metal oxide arrester). First, the pre-processing of the collected MOA-related data is performed to standardize the data, and the data set is divided into a training set and a test set. Then the EEMD (Ensemble Empirical Mode Decomposition) analysis and processing is performed on the key feature of leakage current to extract key frequency domain features. Finally, FCM is performed on multiple features in the time and frequency domains to obtain two central points corresponding to the normal state and preliminary aging state of the MOA, respectively. By comparing the distance between the test set data and the two center points to determine whether the MOA has entered a preliminary aging. Through verification and comparison experiments, it is finally determined that the accuracy of the evaluation algorithm can reach more than 95% when the ambiguity is set to 1.5, and the prediction effect is excellent.
