The economic system of mining city is of typical vulnerability characteristics that can be manifested by its high economic sensitivity and lack of response capacity to the gradual depletion of regional mineral resources. Taking fuxin city of Liaoning Province as a case, this paper established an economic vulnerability assessment method integrating BP neural network with vulnerability index, then carried out an economic vulnerability assessment of fuxin during 1989-2006. The results indicate that: 1) Affected by the gradual depletion of regional mineral resources, the economic development of fuxin had kept high economic sensitivity from 1995 to 2001, and the response capacity to cope with and adapt to the impacts of the perturbation of mineral resources was weak and relatively lag. The evolution of economic vulnerability can be divided into three stages: in 1989-1994, the economic vulnerability of fuxin city decreased slowly; in 1995-2001, the beginning stage of economic transformation, the economic vulnerability of fuxin city went up rapidly; in 2002-2006, the economic vulnerability of fuxin city descended and showed a trend to be stable. 2) The influence of economic sensitivity on fuxin′s economic vulnerability is more evident than that of response capacity. 3) The decreasing supply of mineral resources and the simple industrial structure are main factors leading to the economic sensitivity of fuxin. 4) The improvement of economic response capacity of fuxin has typical characteristics of input-driven growth, and external assistance is of great importance to the rapid improvement of economic response capacity of fuxin. And 5) the change from the simple industrial structure to diversified one of fuxin is still unaccomplished, and the contribution of non-coal-based industry to local economic development is relatively limited.

Impact of Environmental Factors on Respiratory Diseases in fuxin city and Its Prediction

Meteorological and Environmental Research 2023年第2期14卷 21-27页

Based on the daily data of visits for respiratory diseases in two grade A hospitals as well as meteorological factors and air pollution in fuxin city from December 1, 2020 to November 31, 2021, PCA and RBF neural network were used to study the effects of meteorological factors and air pollution on respiratory diseases and predict them. The results showed that the number of daily visits was the largest in winter(accounting for 62.5%), followed by spring(15.2%), and it was the smallest in autumn(only 6.9%). The correlation between the number of daily visits and meteorological factors was higher than that of air pollution factors, and the correlation with temperature and ozone was the highest. The response coefficient of daily visits to each factor increased first and then decreased within 9 d, and the peak was 4-5 d behind. RBF and PCA-RBF neural network models were established to predict the number of daily visits, and the accuracy was 86.3% and 95.2%, respectively.
