| 分别于2005年5～7月和2006年5月在黑龙江省孙吴县境内方圆15km的范围内采用样线法对胎生蜥蜴(Lacerta vivipara)春季的栖息生境进行了初步研究。通过对胎生蜥蜴栖息生境中的15个生境因子进行的频次百分比分析可以看出,在小兴安岭北部胎生蜥蜴春季的最适栖息生境是处于山体半阴半阳坡的中、下坡位,且坡度平缓的蒙古栎(Quercus mongolica)-黑桦(Betula davurica)林中,林间落叶层较厚,具有适中的湿度和光照强度,且土质疏松,人为和天敌的干扰小。结果表明,胎生蜥蜴在春季一般选择具有良好的食物与隐蔽条件,以及能够提供充足热量的栖息生境,这是该物种对高纬度低温环境的一种适应。 |
| 英文摘要: |
| 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. |
