【摘要】 生态因子对生物的生长、发育、生殖、行为和分布有着直接或间接的影响。两栖动物是一类在个体发育中经历幼体水生和成体水陆兼栖生活的变温动物。由于其生理特征和发育特性,决定了它们受环境影响较大。本文主要从生态因子中气候因子着手,利用地理信息系统(GIS)技术对贵州气候分布图和贵州有尾两栖动物分布图的合成比较,来探讨气候因子生态作用对贵州有尾两栖类动物分布的影响。结果发现贵州有尾类两栖动物的分布受到气候因子温度、降水和光照因素的综合制约。更多还原

【Abstract】 Ecological factors have direct or indirect impacts on growth, development, reproduction, behavior and distribution of living organisms. Amphibians are ectothermic vertebrates that are sensitive to climate factors. We explored the effects of the climate factors on the distribution of Caudata in Guizhou through the synthetic comparison made by using GIS between climate and distribution graphic of Caudata in Guizhou,paying particular attention to the climate factors. Our data indicate that climate factors such as temperature, precipitation and illumination play a central role in determining the distribution of Caudata in Guizhou.更多还原
