中文摘要： 琥珀螺科是一个特殊的类群，在软体动物从水生到陆生的进化史上具有重要的意义，有些还是重要的媒介贝类和农果业的害虫。我国琥珀螺科仅报道了一属（琥珀螺属）、26种，其中有40%分布在新疆。由于缺少对已知种类解剖学、齿舌、颚片等主要分类指标的研究及系统的野外调查，至今仍不清楚我国琥珀螺科的资源状况，我国琥珀螺科是否仅有此一属和属下类群如何划分等问题。此项目以已有的新疆琥珀螺记载资料和标本为基础，通过系统的野外补点调查，摸清琥珀螺科在新疆的种类和地理分布情况；以琥珀螺科形态学研究为重点（生殖系统的比较解剖为主，结合壳相特征及齿舌、颚片扫描电镜的研究），对疑难种类辅以分子分析的方法，进行分类学研究，厘清新疆琥珀螺科的种类；在上述研究的基础上，运用支序分析的方法，分析其系统演化关系。研究结果有助于学科的发展，也有实践意义。

英文摘要： The snails of Succineidae are amphibious belonging to Stylommatophora, Pulmonata of Gastropoda. Succineidae is a special taxon with great value in the evolution of the mollusca from aquatic to terrestrial. Some of them are agricultural pests and important intermediate hosts of parasites of domestic animals. In China, only one genus（Succinea）, 26 species have been reported, of which 10 species (about 40%) are distributed in Xinjiang. However, the studies on the known species of this taxon from China were only limited on the descriptions of shell characters and records of species distribution information. Because of lake of the data of taxonomical characters on anatomy, radula and jaws and systematic field survey, the following questions of Succineidae in China are remained: shortage of the resources information of Succineidae in China, whether there is only one genus in China and how to divide the taxa under the genus. Based on the data records and the specimen collectons we have possessed, this project was intended to make clear the number of species and the geographical distribution of Succineidae in Xinjiang by systematic field investigation. Focused on morphological characters (mainly on coparetive anatomical characters of genital system together with shell feathers and radula and jaw data) assisting with mol
