Abstract: Objective Study on relationship of the environment factors with the populations of Anopheles sinensis and An.jeyporiensis, and explore the possible influence of the new villages building which was part of the Chinese west development plan in southern part of Yunnan province on these two vector populations. Methods The relationship of populations of An.sinensis and An.jeyporiensis with the environment factors in southern part of Yunnan province were studied using geographic information system(GIS) system. Results The dominance of An.sinensis could be mimiced by linearity model with DTF and KFA [d=0.3621-3.26×10^-4×DTF^-8.0854×10^-7×KFA (R²=0.642, F test P=0.000)]; The dominance of An.sinensis had the negative relationship with the DTF (Person=-0.683, P=0.002) and the KFA (Person=-0.735, P=0.001). The population density of An.jeyporiensis could be mimiced by linearity model with KRL [Ni=263-0.0541×KRL (R₂=0.633, F test P=0.000)], and it had the negative relationship with the KRL (Person=-0.825, P=0.000). The dominance of An.jeyporiensis could be mimiced by linearity model with DTF [d=7.9204×10^-4×DTF-0.0232 (R²=0.267, F test P=0.023)], and it had the positive relationship with DTF (Person=0.562, P=0.012). Conclusion In the process of new villages building, the changing of some environment factors origining from building action could lead to population fluctuation of these two malaria vectors.
