The data, vectorial capacity of Anopheles sinensis in the suburb of Jining city, Shandong Province in 1975, in 1980-1984, and the average gland infection rate of Anopheles sinensis infected with Plasmodium vivax artificially, were calculated by using Macdonald formula (1957). The basic reproduction rates were 4.44, 6.47 and 4.25 in the years 1975, 1980 and 1981, respectively. In 1982-1984, the rate was reduced to 0.69, 0.41 and 0.1, respectively. Since 1982, the incidence rate of malaria in the areas was reduced by 80% annually, indicating that the malaria transmission had been decreased obviously.
采用Macdonald公式（1957年）计算了1975年、1980 - 1984年山东省济宁市郊区中华按蚊的媒介能量以及人工感染间日疟原虫的中华按蚊平均腺感染率。1975年、1980年和1981年的基本繁殖率分别为4.44、6.47和4.25。1982 - 1984年，该率分别降至0.69、0.41和0.1。自1982年以来，该地区疟疾发病率每年下降80%，表明疟疾传播已明显减少。
