Abstract: When the population dynamic of urban vector and its influencing factors has been well known, it will act a great instructing effect on the management of urban vector. This research has selected the standard variance as the index of month temperature change. Based on the Grey Relative analysis, the research has been made on the relationship between the population density of urban vector and the month highest temperature, the month lowest temperature, the month temperature change and the month precipitation days. The result shows that precipitation days and month temperature change are two the most important factors influencing cockroach population, second the highest temperature and lowest temperature. The most important factor influencing mosquito population is the lowest temperature, and then the highest temperature, month temperature change and precipitation days. Based on the Fourier Series, the research simulates the dynamic change of cockroach from 1996 to 1997 and rodent population from 1996 to 1998, and the simulated result is coincident with the practical investigation.
