宁夏中卫石炭纪晚期有翅昆虫的辐射演化

对宁夏中卫市下河沿地区上石炭统地层中较为丰富的早期有翅昆虫化石展开经典分类、形态学、生物学、系统发育学、生物地理学等研究。揭示我国晚石炭世昆虫化石群落面貌特征，查明优势种、特有种及特定生境指示种。重点解决几个代表性类群（古翅类：蜻蜓目；多新翅类：古直翅总目、蛩蠊目、网翅目、積翅目）的物种鉴定、系统发育关系及关键特征的分化等问题。对重要类群进行功能形态分析，查明其生物学特性并探索其演化历程。为有翅昆虫的起源、演化、扩散乃至昆虫起源和早期演化研究提供最基础的数据；为地层划分、对比和地质时代的确定提供可靠的地史材料和根据。

This project will perform a series research on classic taxonomy, morphology, biology, systematic, geobiology etc. of upper Carboniferous pterygota, based on the abundant and diverse collections from Xiaheyan village, Zhongwei City, Ningxia, China. It will give a generally scenario of Xiaheyan entomo-fauna, and help us to know the key species, local species and environmantal indicator species. Besides, we will focus on the classification, systematics , the divergence and evolution of key morphological characters of the key taxa (Palaeoptera: Odonata; Polyneoptera: Archaeorthoptera, Grylloblattida,Dictyoptera, Plecoptera). Further, conduct the functional morphology analysis of the key taxa; investigate their biological properties and evolutionary course. All this outcomes can provide the most fundamental knowledge for understanding the origin, evolution and distribution of pterygota, or even insects; also provide the evidently biological materials for studying geologictime and stratigraphic subdivision.
