Based on the field investigation of the leakage of pipeline transportation and combining with the latest research direction of emergency management mechanism, it was found that the stochastic Petri net model suitable for this kind of problem was modeling. Taking the Huangdao oil pipeline leakage accident as an example, the data of emergency management flow of pipeline transportation leakage were collected and processed, and isomorphism Markov chain to study the change utilization rate and average delay time was used. The results of the study indicated that the coordinated treatment of pipeline leakage systems, protection of the affected areas and the transfer of the masses took the most time in emergency operations. Therefore, intensifying the cooperation between the central construction administrative agencies and the local construction administrative agencies and perfecting the mass transfer and resettlement system were reasonable measures to strengthen emergency management of pipeline leakage and minimize economic losses.

According to the background of views on further strengthening of the urban planning and construction promulgated by the state council, the new open area of the status quo was explored at home and abroad in recent years. And four typical residential areas in A city were taken as examples, combined with investigation in A city, and the pros and cons of the open area were preliminary analyzed. And by using the simulation software to simulate plot open, a variety of factors under the condition of MATLAB mathematical model was established. And before and after the impacts on the surrounding area in the open were quantitatively compared. According to the results, and puts forward the following suggestions: Building the open district should adhere to the peoplecentered principle, should from the laws and regulations, regulatory system, social environment and other aspects to obtain, reasonable planning and construction of the community. The results can provide reference for the construction and management of open community in A city of liaoning province.

Based on a huge number of literatures about income satisfaction and measure of income satisfaction, combined with the actual situation in Liaoning province, a household income satisfaction measure scale in Liaoning province were designed, and then a household income satisfaction measure model in Liaoning province was built. Through the use of factor analysis, four factors that affected the satisfaction degree of family income in Liaoning province were extracted. They were self value realization factor, family expenses factor, family income factor and social environment factor. The results show that residents in Liaoning province were dissatisfied with the level of household income.
