陕西临潼零口文化遗址脊椎动物遗骸的古环境意义

陕西省临潼零口遗址脊椎动物遗骸有Rhizomys sinensis,Hystrix hodgsoni,Nyctereutes procyonoides,Meles meles,moschus sp.,Ceruvs hortulorum,Elaphurus davidianus,Caprinae,Gazella sp.,Bovinae,Sus domesticus,Phasianidae和Cyprinoid，可分为5层位，其年代为7300aBP 380-6220aBP 407和仰韶西王村类型。动物生态、动物地理及其他气候替代性指标显示了零口文化和仰韶文化的1500年间包含了2个相连续、但不完整的气候演变周期。每个气候演化延续时间约为700－800a。气候演化周期与文化发展周期基本吻合。

Vertebrate Remains of the Lingkou Site and Its Paleoenviroment Significance

The age of the Lingkou archaeological site, Lintong, Shaanxi, is about 7300-6220 a BP and the Late Stage Yangshao Culture. The remains presented as 157 individuals belong to 13 spicies: Rhizomys sinensis, Hystrix hodgsoni, Nyctereutes procyonoides, Meles meles, Moschus sp. , Cervus hortulorum, Elaphurus davidianus, Caprinae, Gazella sp. , Bovinae, Sus domesticus, Phasianidae and Cyprinoid. Those vertebrate remains can be divided into 5 layers. During 7300-6930 a BP and 6600 - 6420 a BP plenty of browsing cervid fauna occurred, showing an obviously warm and humid climate condition. The faunas between 6930-6660 a BP and 6420-6220 a BP are different distinctly from 7300 - 6930 a BP and 6600-6420 a BP, and animals living in steppes became dominant. The evolution of the faunal ecological sequence during the stages indicates that the natural environment was interchanged from semiarid veldt to dry steppe, and gradually to the modern climate.
