To provide a climate basis for scientific planning of the development of industry, agriculture, tourism and cities, and to reduce risks and economic losses caused by meteorological disasters.The results show that the annual average temperature indicate a slow upward trend. The annual precipitation and the precipitation day show a decreasing trend, the interdecadal change of storm rainfall also shows a decreasing trend, while the change of heavy storm rainfall decreases first then increases. The annual variation of the average wind speed shows a decreasing trend, so as the annual gale day does. The studies of major meteorological disasters show that extreme weather events such as typhoon, heavy storm and extreme temperature occurred successively in Qinhuangdao in recent ten years, ranking a higher frequency than former time. As a result, the risk and impact of meteorological disasters have been aggravated. Since the extreme weather in recent ten years occurred more locally with higher intensity, the weather forecast is becoming more difficult and the meteorological risk is further enhanced.

The empirical relationship and sedimentary environment characteristics are analyzed. In connection with the soil layer, which has a long transport distance and a relatively small particle size, the shear wave velocity is relatively low. The empirical relationship between depth and shear wave velocity in the depth of 20m depth of the soil layer with obvious sedimentary features in the Jiaozhou Bay area of Qingdao is given. For the soil layer without obvious sedimentary features, the sedimentary features of the remaining strata of the borehole are used for classification, which improves the fitting degree of the empirical relationship and reduces the error, thus giving a method to estimat shear wave velocity of borehole using bore histogram with obvious sedimentary characteristics.

In the first step, the three important factors of interaction between criminals and police are modeled as a zero-sum noncooperative game, and the risk value of each patrol area is obtained by calculating the mixed strategy Nash equilibrium. In the second step, the Shapley values of three different threat levels are calculated according to the rates of criminal events within three time periods. Finally, the Shapley value is derived based on the three criminal threat levels for each district. A fair allocation of police personnel based on the Shapley value is made with a minimum set of personnel deployment costs. This study used the 2016 San Francisco Public Security Bureau's open data for consolidation and calculations to validate the model. The experimental results show that police planners can use this framework to quantitatively evaluate the criminal threat in each district when deciding upon the deployment of patrol officers for three shifts per day.
