This paper, based on the information obtained both from home and abroad, discusses the ecological and physiological characte rastics of yak in adapting to the enviroment of low oxygencontent in the air. Yak have well-developed heart and lungs, and their tracheas are thick and short. The range of respir ation and pulse of yak varies greatly. Yak have a high content of red cell and hemoglobin in the blood, and the composition of types of hemoglobin is different from that of ordinary cattle. The early-period fetus'...

This paper, based on the information obtained both from home and abroad, discusses the ecological and physiological characte rastics of yak in adapting to the enviroment of low oxygencontent in the air. Yak have well-developed heart and lungs, and their tracheas are thick and short. The range of respir ation and pulse of yak varies greatly. Yak have a high content of red cell and hemoglobin in the blood, and the composition of types of hemoglobin is different from that of ordinary cattle. The early-period fetus' hemoglobin was found in the newborn's blood. The characterastics mentioned above have been discussed in the paper and some recommendations for yak. breeding and man- agement have also been given.

本文根据国内外有关资料,阐述了牦牛适应少氧环境的生态生理特性,主要表现在胸腔和心、肺脏发达;气管粗短,呼吸、脉搏变化幅度大;血液中红细胞和血红蛋白含量高,血红蛋白类型组成变化较特殊,初生牦牛犊血液中含有早期胎儿血红蛋白等。并对上述特性作了初步分析和讨论。本文为牦牛选育、饲牧管理提供了一些依据。

This paper reports the anatomical results of the parasympathetic nervous system of goose. The parasympathetic components are of cranial nerves Ⅲ, Ⅶ, Ⅸ, Ⅹ and caudal synsacral pelvic nerves. The essential characters of parasympathetic fibers in the glossopharyngeal nerve (Ⅸ) and vagus nerve(Ⅹ) ultimately innervate the cervical, thoracic and abdominal viscera. There is a vago-glossopharyngeal communicating rarnus connects to the glossopharyngeal ganglion. The glossopharyngeal ganglion has a longer descending ramus,...

This paper reports the anatomical results of the parasympathetic nervous system of goose. The parasympathetic components are of cranial nerves Ⅲ, Ⅶ, Ⅸ, Ⅹ and caudal synsacral pelvic nerves. The essential characters of parasympathetic fibers in the glossopharyngeal nerve (Ⅸ) and vagus nerve(Ⅹ) ultimately innervate the cervical, thoracic and abdominal viscera. There is a vago-glossopharyngeal communicating rarnus connects to the glossopharyngeal ganglion. The glossopharyngeal ganglion has a longer descending ramus, which innervates the trachea, esophagus arid thyroid gland. The preganglionic fibers of pelvic nerve are found in ventral roots of synsacral spinal nerves 7—10, while that of pelvic nerves is distributed to the ureter, duetus deferens, rectum, oviduct and urodeum.

草鹅的副交感神经,除头面部动眼和面神经副交感纤维外,颈部迷走、舌咽神经广泛支配着气管和食道。舌咽神经节有专一连接颈动脉窦和颈动脉体的窦神经。迷走结状神经节有连接后颈动脉体的专一功能性神经。右侧迷走心肺神经有与主动脉弓相连的减压纤维。舌咽神经的下行支,除支配气管食道的纤维外,其末端纤维还分布到甲状腺以及食道膨大部。支配胸部心脏和肺的副交感纤维,均来自两侧迷走干,有从结状节后端发出的心脏神经长支,也有从相应部位迷走干发出的心肺神经短支,分别入心脏和肺。腹部两侧迷走主干,在食道末端形成了食道腹干,其分支经腺胃腹面向腹部有关内脏分布。右侧迷走干在返神经基部发出一独立的神经向后延伸,在食道末端形成食道背干,其分支分布于腺胃和肌胃的背侧面。腰荐部副交感纤维,分别来自第七、八、九、十对腰荐脊神经腹支,形成两侧盆神经,向骨盆内有关脏器分布。新疆草鹅作为一种新型家禽,对其饲养,繁殖及生态生理特性,特别对提高其生产能力的调控效应方面应作深入研究。本文作者在研究其交感神经基础上,又对其副交感神经进行了系统的解剖和探讨,现将结果整理于后。

On the coast of Shandong Province there are some coastal psammophilous vegetations which consist of psammophytes and some sandy tolerant plants. They are characterized by: 1. Simple floristic: There are 68 species of spermatophyte Which are subordinate to 55 gen- eras in 22 families. 2 The plant flora composition on families or generas has some obvious features that the veg- etation in the North Temperate Zone and the Temperate zone has. It also involves a part of tropi- cal plants and subutropical plants....

On the coast of Shandong Province there are some coastal psammophilous vegetations which consist of psammophytes and some sandy tolerant plants. They are characterized by: 1. Simple floristic: There are 68 species of spermatophyte Which are subordinate to 55 gen- eras in 22 families. 2 The plant flora composition on families or generas has some obvious features that the veg- etation in the North Temperate Zone and the Temperate zone has. It also involves a part of tropi- cal plants and subutropical plants. 3. Most floral element of psammophytic belongs to boreal distribution speices, whereas a quantity of sandy tolerant plantsin cosmopolitan. 4. Xeric traits: plants in the region have some physiological eco--characteristics to tolerate dry. poor. hot. and salt environments. Morphologically. they have short, prostrate, thorny, and succulent aboveground componens and extraordinarily perfeca rootsystems. The protection. exploitation and utilization to the psammophytie vegetation on the coast of Shandong Province is discussed in the end of the paper.

山东海岸沙滩滨海沙生植被由沙生植物及部分耐沙植物组成,其特点是: (1)组成植物种类简单,有种子植物68种,隶属于22科55属;(2)植物科、属的区系地理成分具有明显的温带、北温带性质,并含有一定数量的热带、亚热带成分;(3)沙生植物种的区系成分多数是北方分布的种类、而耐沙植物则大多数是广布种;(4)植被具有旱生性质,组成植物有耐旱、耐瘠、耐热、耐盐的生态生理特性,在形态上表现为低矮、匍匐、具刺、肉质和根系特别发达等形态学特征。最后从植物生态学角度论述了山东海岸沙生植被的保护与开发利用。滨海沙生植被是海岸带生态系统的重要组成部分,是沙滩生态系统中最基本的生物资源,其种群数量变动对沙滩生态及海岸带环境有着重大影响。对滨海沙生植被的研究国内虽有报道,但还无人对地处暖温带气候区山东的滨海沙生植被种类组成及其群落性质进行系统地研究。
