This paper presents the results of our studies on the faunal and ecology distribution of birds in Wuliangsuhai region of Nei Mongol, which were carried out during 1983—1986. Wuliangsuhai is the second large freshwater lake in Inner Mongolia. Its area is over 200 square kilometres, where waterweeds grow thickly and reeds are luxuriant. There are plenty of food and concealed conditions, which provide the perch for a great number of wading and natatorial birds. 124 species of birds collected belong to 75 genera,...

This paper presents the results of our studies on the faunal and ecology distribution of birds in Wuliangsuhai region of Nei Mongol, which were carried out during 1983—1986. Wuliangsuhai is the second large freshwater lake in Inner Mongolia. Its area is over 200 square kilometres, where waterweeds grow thickly and reeds are luxuriant. There are plenty of food and concealed conditions, which provide the perch for a great number of wading and natatorial birds. 124 species of birds collected belong to 75 genera, 35 families, 14orders. Among them, 64 species are summer residents 41 species migrants, 19 species residents and 5 species new records for Nei Mongol. These birds are distributed in five types of ecological environment. As the silt is deposited in the bottom of the lake, water in lake gets shallow, and man's economic activities have exerted a tremendous influence so that primary productivity is more than secondary productivity in lake and ecosystem is rapidly losing balance. Its succession process may result in reed swamp down to salinized soil desert. At present, the avifaunal is gradually turning poor. Some of bigger birds, for example, Cygnus olor, Pelecanus philippensis, Anser anser, Egretta alba and Ardea cinerea, etc. have decreased clearly. Such birds of prey as Circus aeruginosus have been almost stamped out in the lake.

乌梁素海为内蒙古第二大淡水湖。面积200多平方公里。这里水草丛生,芦苇繁茂,有充足的食料和隐蔽条件,为众多的游禽和涉禽提供了栖息条件。该地有鸟类124种,隶属于75属35科14目。其中夏候鸟64种,旅鸟41种,留鸟19种。5种为内蒙古鸟类分布新记录。这些鸟分布于5种不同的生态环境中。由于湖底沉积,湖水变浅以及人类经济活动的严重冲击,使得这里初级生产力发达,次初生产力不足,生态系统正在迅速失去平衡,其演替的过程可能是芦苇潍以至盐化荒漠。目前,鸟类区系正在逐步走向贫乏,一些大型鸟类如疣鼻天鹅、斑嘴鹈鹕、灰雁、白鹭、苍鹭等明显减少,白头鹞等猛禽几乎绝迹。

抗战时期西北工业合作运动弥补了战时工业生产力的不足,对战时西北经济生活产生了积极的影响。它以抗战建国为总体目标,尽管始终面临资金缺乏等困难,但它仍然对稳定战时西北经济生活作出了自己的贡献。战时中国工业区的破坏和因运输困难使外货输入减少是它产生的前提,而一旦这种条件消失,西北工合就可能面临严重的生存危机。
