Of which dwelling building is 40.2, livestock building is 68.8, but the latter is more higher than the former. The density on an avsrage a year is 41.7, 36.6 and 42.1 in dwelling buildingain 1987, 1988 and 1989, and is 84.4, 69.7 and 52.3 in 1987, 1988 and 1989, in livestock building respectively. Although the local climate is not change obviously in the past, because paddy field and lotas flower-ponds were gradually decreaseing in the past three years so that it make the density of mosquito decreased in general For that reason, the work of surveillance of mosquito population variation play more important role in control of mosquitoborne disease and its prevalence. It possessed important epidemiological meaning.
