两栖类动物

Biodiversity is one of the front areas of current biological research. The mechanisms of the formation, spatial distribution pattern, conservation and utilization of biodiversity have been an important area of biological and environmental research. In this study, through analyses of data about plant diversity, animal diversity, geographic factors, climatic factors, and energy factors by use of GIS software, statistic software and ecology software, the mainland of China was divided into 241 small districts of 2° by 2°. The environmental factors in each district were analyzed and isopleth maps of environmental elements were depicted.

生物多样性是当今生物学研究的热点问题之一，生物多样性的形成机制和分布格局以及保护利用问题一直是生物学和环境科学所研究的重要内容，本文由此出发，以中国陆地为研究区域，通过植物多样性数据、动物多样性数据、地理因子、气候因子、能量因子等资料，利用MAPGIS、MAPINFO等GIS软件，SPSS、DPS等统计学软件以及CANOCO等生态学软件，将中国陆地划分为241个小区，分析了各区内的环境特点，统计了各区内生物多样性的数量，并绘出环境因子等值线图，中国陆地种子植物科、属、种，裸子植物种、蕨类植物种、兽类、鸟类、爬行类、两栖类种数的等值线分布图，对中国陆地植物、动物多样性现状、分布格局及与环境因子的关系进行了研究。

Sixteen ( 15 new) amphibian and twenty-two ( 11 new) squamate species have been reported across China, including the oldest Chinese tetrapod Sinostega pani from the Late Devonian of Ningxia Hui Autonomous Region, the large stereospondyl amphibian Yuanansuchus laticeps from the Middle Triassic of Hubei Province, Late Jurassic/Early Cretaceous lissamphibians ( e. G., the anurans Callobatrachus sanyanensis and Mesophryne beipiaoensis, the caudates Jeholotriton paradoxus and Laccotriton subsolanus) from Northeast China, Paleogene lizards (e. G., Brevidensilacerta xichuanensis and Tinosaurus yuanquensis) from North China, and numerous lizards from the Late Cretaceous of Nei Mongol Autonomous Region.
