中文摘要： 肉苁蓉为我国西北地区特有寄生性名贵药材，由于其野生资源濒临枯竭，已被列入《濒危动植物种国际贸易公约》附录II，国家鼓励发展人工种植以满足市场需求。新疆是我国肉苁蓉资源分布区域最广、种类最多、种质资源最丰富的省区，针对其肉苁蓉资源本底不清，人工种植种源混乱，药材产量及质量不稳定的现状。本项目拟对新疆肉苁蓉及寄主植物种质进行广泛收集，应用传统方法与现代研究技术相结合，从物种、遗传多样性水平和药材品质等方面开展系统评价，建立客观评价肉苁蓉及其寄主种质资源的技术体系；明确肉苁蓉、寄主物种分类及两者间的对应关系；揭示肉苁蓉品质性状与寄主和生态因子的相关性；构建新疆肉苁蓉及寄主植物种质资源库，为肉苁蓉及寄主资源保护和利用提供科学依据和物质基础。研究结果对肉苁蓉与寄主优良种质的发掘、繁育、引种栽培和规范化种植基地建设具有积极指导作用，对保证肉苁蓉药材质量稳定可控、促进新疆经济发展及生态建设具有重要意义。

英文摘要： Cistanches Herba, one of precious traditional Chinese medicine particularly in northwest China, which original wild plant resources dropped sharply in recent years, and were listed in the Appendix II of Endangered species of wild fauna and flora of the convention on international trade (CITES). Xinjiang is the province with the largest natural distribution area of Cistanches Herba and most abundant plant species. Nowadays germplasm resources of Cistanches Herba in Xinjiang are in rich diversity but without comprehensive，systematic and scientific evaluation. Aiming at this situation，our project is to investigate and collect germplasm resources of Cistanches Herba and its host plant systematically, and then traditional research methods would be combined with modern research techniques to study the resource diversity and systematic assessment from the plant species diversity, genetic diversity, and quality traits diversity, and the relationship with habitat factors and host species. We would try to clear genetic structure of Cistanches Herba population and its diversity performance under different ecological environmental factors; to set up rapid identification and objective evaluation method system of Cistanches Herba. The dominant, particular and representative population of Cistanches Herba in Xinjiang area would be identified to build the Cistanches Herba germplasm resources repository of Xinjiang, providing a scientific basis and germplasm resources reserves for resources protection, artificial breeding and sustainable utilization of the Chinese endangered medicinal plant Cistanches Herba. Research results will provide a research basis and technical guidance for Cistanches Herba seed breeding, planting area enlarging and Good Agricultural Practices (GAP) base construction, supporting technically for tasks on the stable quality of raw material and health care products of Cistanches Herba. What’s more, it is of great significance to promote environmental protection, ecological construction and people's economic income increase of arid areas in China.
