With the acceleration of the pace of global economic integration and the recent development of the number, quality and scale of domestic chemical parks, domestic new chemical projects have shown a trend of gathering and development in various chemical parks, but with Jiangsu Xiangshui Chemical Park “ The occurrence of the 321" explosion accident, China's chemical park management problem has once again been highlighted. As an important growth point of the economy, the chemical park brings huge economic benefits, but it also brings serious environmental impact and security instability. Under the background of the transformation and upgrading of the entire chemical industry in China and the transformation of new and old kinetic energy, the chemical industry park has played a strong guiding role in the direction of industrial development, capacity adjustment and division of labor, and support for production factors. At the same time, chemical enterprises in the chemical parks have concentrated development, including many. A wide range of hazardous chemicals and major hazards are involved, and hidden dangers such as leakage, fire, explosion and other major safety accidents are lurking. The management of chemical parks is particularly important for the development and even survival of the entire chemical park. This paper analyzes the status quo of safety and emergency in chemical parks, analyzes and summarizes the problems existing in the management of domestic chemical parks, and puts forward countermeasures and suggestions for solving the problems of chemical park management in China, in order to improve the management status of chemical parks in China and promote the science of chemical parks.

朱建淼,陈三强 浙江省安全生产科学研究院、浙江省安全工程与技术研究重点实验室,杭州 310012 zjmsx@163.com Abstract:The principle,adaptive hidden danger identification characteristic and features of an intelligent power system are introduced in this paper. The types and distributions of common hidden dangers in electrical circuits are analyzed from a systematic perspective based on the monitoring data, which can provide basic ideas and methods for the further rectification directions of the circuits. According to an uncompleted statistics, approximately 15000 sets of intelligent power system are installed in Zhejiang Province. 583,665 hidden dangers have been monitored in which the hidden dangers of current take 41.2%, the hidden dangers of residual current occupy 37.3% and the hidden dangers of cable temperature contributes 21.5%. By the construction of socialized service system through intelligent electricity and electric fire prevention and control, the accurate location and accurate investigation of an electrical fire hazard can be realized, which can effectively reduce the hidden danger of safety in the process of electricity use, reduce the number of electric fires, and raise the risk awareness of the enterprise's electricity safety. The electrical fire accidents have dropped by more than 30% in the area where the intelligent power system is installed.

In this paper, the NCEP reanalysis data and the sea surface temperature data are used to diagnose the development process of the intense tropical cyclone “IDAI” generated in the SouthWest Indian Ocean. The results show that the presence of the high pressure ridge in the northeast and the weak high pressure in the south makes “IDAI” moving slowly or even stagnantly. According to the intensity, the development of “IDAI” can be divided into three processes: the rapid strengthening process, the weakening maintenance process and the secondary strengthening process. Then it eventually developed into an intense tropical cyclone. The high sea temperature, the relatively small vertical wind shear and the favorable high-level divergence conditions are benifit environmental conditions for its rapid strengthening; during its development process, the external water vapor transport is weak, the water vapor and heat mainly come from the ocean; the eye wall replacement process causes the second strengthening of its intensity. Finally it landed in Mozambique with an intensity of intense tropical cyclone.

Based on daily precipitation of Qianxi and six surrounding counties from 1984 to 2015, we estimate the risk of drought in Qianxi county during a series of return periods by probability distribution. So does the chestnut-drought risk by distribution of chestnut and relative risk grade. It is concluded that the risk of drought is higher in the southwest of Qianxi. The drought area and intensity increase with the augment of return period. Percentage of precipitation departure is -43% in Baimiaozi, Xingcheng, Xinzhuangzi and Donglianhua township when the return period is 30a. It is -52% when the return period being 100a. The distributions of chestnuts are largest in Yangjiayu and Shimenzi village, Hanerzhuang township, which are 683 and 670 ha. Influenced by hazard factor and bearing body, the risk grade is highest in most areas of Hanerzhuang, Luanyang, Shangying and Jinchangyu town.
