本文分析了山东省25年(1959～1986)间蚊虫密度和疟疾发病率的系统年报,提出山东省水田区蚊虫密度最高峰是气温依赖性的;旱田区是雨汛依赖性的。鲁西、鲁南水田区,疟疾发病率高峰是在蚊虫密度最高峰之后,是由蚊虫密度最高峰引起的,故成为疟疾高发区;鲁西鲁南和鲁东旱田区蚊虫密度最高峰是雨汛依赖性的,鲁东水田区是气温依赖性的,由于出现时间晚,气温已下降,故不能导致疟发新高峰,亦即蚊虫密度最高峰在疟发高峰之后,因此.这些地区成为低疟区。
This paper analyzes the systematic annual reports of mosquito density and malaria incidence in Shandong Province for 25 years (1959 ~ 1986), and suggests that the highest mosquito density in paddy fields in Shandong is temperature-dependent; that in dry land areas is rainy season-dependent. Luxi and Lunan paddy fields, the highest incidence of malaria is caused by the peak of mosquito density after it reaches the peak of mosquito density, so it has become a high incidence area of malaria. The highest peak of mosquito density in Luxi Lunan and Ludong dry-land areas is rain Flood-dependent, paddy fields in Ludong are temperature-dependent and due to the late appearance of the weather, the temperature has dropped, it can not lead to a new peak of malaria, ie the highest peak of mosquito density after the peak of malaria. Therefore, these areas have become low Malaria area.
