在生物多样性问题依然严重和全球环境变化的背景下，生物地理学研究的重要性应该被更加重视，研究重要动物类群的生物地理格局演化、物种多样性分化模式和机制，不但有重要的科学理论意义，而且对可持续发展科学决策有重要价值。本项目以与农林生产密切相关、研究基础很好的扁蚜类昆虫为研究模型，使用GIS、物种分布模型、分子系统发育、谱系地理学等方法，基于整合性生物地理学研究模式的实践，期望在不同尺度动物地理格局演化机制、东洋区动物地理格局演化、植食性昆虫物种多样性分化等重要科学问题方面取得突破，也为制定合理的多样性保护策略、更好地理解农林害虫的进化机制提供科学证据。

Under the background of biodiversity crisis and global climate change, the importance of evidences from biogeography researches in scientific decision-making should be prioritized. Understanding the evolution of biogeographical patterns, modes and mechanisms of speciation of important animal groups is of great value to not only developments of related disciplines, but also policy-making in sustainable development. This program aims to improve our understandings of zoogeographical evolution across spatial and temporal scales, the biogeography in Oriental realm, as well as the speciation of phytophagous insects by using Hormaphidinae, an insect group with years of relatedd studies, as research model. An integrated research scheme incorporating approaches such as GIS, species distribution modeling, molecular phylogenetics and phylogeography will be applied. The results and research scheme of this program are expected to also facilitate the understanding of the evolution of agricultural and forestry pests and provide scientific evidences for policy-making in biodiversity conservation.
