The habitat character of Lacerta vivipara was studied in the range 15 km at Sunwu Country,Heilongjiang Province by using line-transect method in May, June, 2005 and May, 2006. Fifteen environment factors were collected and analyzed. The most suitable habitat of L.vivipara located in forests dominated by Quercus mongolica-Btula davurica at middle and lower position in the gentle slope with half sunny and half shade expose in spring.The location that L.vivipara was found usually was heavily covered by fallen leaves with moderate humidity and sunshine, soft soil, less natural enemies and human disturbance. In spring L.vivipara generally select habitat that can provide rich food resource, good cover and sufficient heat. The habitat selection in species by L.vivipara was its adaptation strategy to the environment in high latitude.
