摘　　要：在全国岩溶洞穴中 ,石花洞层数最多 (8层 )、石盾最多 (约 2 0 0个 )、石笋的叠置关系最明显、月奶石发育最好。首次发现碳酸钙微层理和膜足硬肢马陆穴居动物 ,首次在碳酸钙中使用 ESR和 2 10 Pb测年法 ,首次进行氡浓度研究 ,首次从地质学、气象学和环境学进行多角度综合研究。Shihua Cave,which as yet has the most levels(8) and stone shields(about\ 200)in Chinese caves,possesses obvious superimposed relationship of speleothems,and well developed moonmilk stone.Speleothem microbanding and Skleroprotopus membranipedalis sp.nov. were first founded in the cave.ESR and 210 Pb dating methods were first used and the concentrations of Radon was studied.As well,polyangle synthesized research on geology,meteorology and environmental geology was first carried out.
