黑龙江省两栖爬行动物物种分布与生态因子关系的分析

通过2000～2006年对黑龙江省两栖爬行动物的种类及分布情况进行实地深入调查,并结合黑龙江省两栖爬行动物研究的历史资料及现代有关成果,从经纬度、年平均温度、年平均降水量、海拔、生境、垂直分布等生态因子对黑龙江省两栖爬行动物的物种分布格局进行了探讨,结果表明黑龙江省两栖爬行动物的物种总数与海拔、纬度成负相关关系;而与年平均温度、年平均降水量成正相关关系;在经度E128°～E130°之间物种数较多,其他地区则较少;灌丛、阔叶林等为黑龙江省两栖爬行动物适栖生境.在平原、丘陵低山灌丛、山地针阔叶混交林分布着全省所有的物种.

AN ANALYSIS OF RELATIONSHIP BETWEEN ECOLOGICAL FACTORS AND NUMBER OF SPECIES OF AMPHIBIANS AND REPTILES IN HEILONGJIANG PROVINCE

Through our large scale investigating on species and distribution of amphibians and reptiles in Hei- longjiang province from 2000 to 2006,we used ecological factors including different latitude and longitude, yearly average temperature and precipitation,altitude,different habitat,vertical distribution,which based on their historic data and relevant modem achievements to make further studies on the distributive structure of am- phibians and reptiles in Heilongjiang province.The results summed above indicated that there are negative correlation between the number of species with latitude and altitude,there are positive correlation between the number of species with yearly average temperature.and precipitation.There are large quantity of both animals in these regions whose longitudes are between E128 to El30,and there are much fewer animals in other re- gions.Bush wood and leafy wood zone are very ideal for the survival of amphibians and reptiles in all kinds of habitats,There are all the species of our province in plain,bush wood of highland and lowland,mountainous conifer leafy mixed.
