我国是生物多样性保护研究热点地区之一，确定生物多样性格局是制定有效保护策略的重要前提，生物地理学方法则可为多样性保护研究提供重要帮助。我国花萤亚科昆虫广泛分布于全国各省区，物种多样性丰富，特有性指数高，以捕食为主，对其生物多样性格局及其保护研究具有重要理论价值和经济意义。本项目首次以我国花萤亚科昆虫为研究对象，在前期工作基础上，综合运用生物统计学与地理信息系统、特有性简约性分析和泛生物地理学的兼容性轨迹分析等生物地理学方法，从物种多样性、区系组成、分布格局与演化等多个角度开展区系与地理分布格局的研究。通过本项研究工作，旨在掌握我国花萤亚科物种多样性特点和区系组成特点，确定总体分布格局和特有种分布格局，揭示物种多样性格局，并确定特有分布区，进而探讨区系起源和演化，为我国生物多样性保护策略的制定提供依据，并为我国动物区系深入研究积累资料，同时为世界花萤亚科地理起源与演化奠定研究基础。

China is one of the hotspots in studying on biodiversity protect, and the biogeographical method is helpful in determination of the pattern of biodiversity, which is the basis of formulating protect strategies. The predatory soldier beetles subfamily Cantharinae of China includes 570 species, which are widely distributed around China and mostly are endemic ones, the study on the distribution pattern of biodiversity and its protect has some theory value and economic importance. In this project, on basis of the previous work, the fauna and distribution pattern of the Cantharinae of China is studied for the first time in the several aspects, including species diversity, faunistic components, distribution pattern and evolution, by using integrative means of Biostatistics, Geographical system analysis (GIS), Parsimony analysis of endemicity (PAE) and Compatible track analysis (CTA). It aims to summarize the characters of species diversity and faunistic components, determine the distribution patterns of all the species and the endemic species as well as the area of endemism, presume the reasons how the distribution pattern forms, and discuss the origin and evolution of the fauna of Cantharinae of China. The results of this project will provide some evidence in formulating the strategies of biodiversity protect, and make some contribution for furthering studying on the biogeographical of China, also make a basis in studying on the geographical origin and evolution of Cantharinae worldwide.
