【摘要】 <正> 安康地区,位于陕西省南部,汉江中游两岸,北部跨秦岭中段南坡,南部处大巴山北麓,与鄂西北、川东北毗邻,整个地理位置在北纬31°48′—33°57′、东经108°10′—110°20′之间(图1)。 由于该区地处陕、川、鄂三省交界的边缘,至今对该区兽类区系及资源状况了解甚少,在国内尚为空白之点。该区兽类种属较多,为陕西省毛皮产量较高的地区;加之,近年来对鄂西北神农架、川东北一带动植物调查的注意,因此报告该区兽类区系及资源状况对了解上述区域有一定意义。更多还原

【Abstract】 A faunal survey was conducted from April 1963 to February, 1966 in theAnkang region of the southern part in Shanxi Province. Collections were madeat the following localities (see map 1): Ningshan (宁陕) , Shiquan (石泉),Hanyin (汉阴) , Ankang (安康 ) , Xnuyang (旬阳) , Langao (岚皋), Pingli(平利) , Baihe (白河) , Ziyang (紫阳 ) , Zhenping (镇坪) .Altogether 2, 989 specimens were collected including 96 species and subspecies, belonging to 26 families and 7 orders.This region, in authors’ view, may be zoogeographically divided into 6 zones :1. Subalpine coniferous forest zone of Tsinling (alt. above 2,500 m) .2. Mid mountain mixed forest zone of Tsinling (alt. 2,500-1,300m).3. Low mountain defoliation and broad leaf and even green broad leaf forest zone of Tsinling (alt. 1,500-800m).4. Cultivated fields zone of Ankang basin (alt. 800-500m).5. Low mountain even green defoliation and broad leaf forest zone of Mountain Taibai Shan (alt. 2,000-1,300 m) .6. Subalpine coniferous forest zone of Mountain Taibai Shan (alt. above 2,200 m).For each of these zones, brief notes are given concerning its faunal characteristics, with due emphasis on representative species.On the southslope of Tsinling, 27% mammals are Palaearctic species, 44% mammals are Oriental species. On the northslope of Mountain Taibai Shan almost 15% of the mammals arc Palaearctic species, 47% are Oriental species.From the above analysis authors conclude that the Mountain Tsinling along with Taibai Shan region is apparently a transitional belt between the Palaearctic and Oriental realms. The oriental elements arc increasing from north to south, while the palaearctic ones are decreasing gradually.更多还原
