在围绕“沙漠生物地毯工程”进行“荒漠地衣固沙固碳缓解沙尘暴及全球变暖的可行性研究”（项目编号：31070018）中发现，荒漠地衣次生代谢产物在不同培养条件下出现了不同结果。为了探索荒漠地衣资源多样性的开发新途径，拟通过多态性微卫星标记(ISSR-TAIL-PCR)法，对荒漠地衣的基因多样性进行分析研究；通过荒漠地衣优化培养调控法以探索打开荒漠地衣资源多样性的开发新途径。该项目将为荒漠地衣资源开发探索新途径提供科学依据、技术支撑和荒漠地衣资源库。该成果将对整个地衣资源的开发具有开拓性意义。..

In order to explore the new way to develop the diversity of desert lichen resources, microsatellite markers for diversity of desert lichen fungi, an ISSR-TAIL-PCR method will be used for analysis of genetic diversity of desert lichen fungi and regulation and control using culture optimization will be available to open a new way for developing the diversity of desert lichen resources. The project will provide scientific evidence，techniques support, and pool of desert lichen resources for a new way to develop the diversity of lichen resources.The result of this project will be groundbreaking for developing the whole lichen resouces as well. Key words: diversity, lichen resources, new way, optimization
