The main factors to threaten large and middle mammals on Zhoushan Islands are area loss, fragmentation, quality descending of the natural habitats which are resulted from human activities and hunting. The area lOSS Of the natural habitats has lost 56. 3%. The natural habitats have been fragmented into many fragments, and the fragmented degree has being deeped, and the quality of the natural habitats was declined in 1912~1950. The threatened history of the large and middle mammals can be divided into three Periods. Before 1912 the large and middle mammals were threatened lighter; the middle and large mammals were threatened heavily in 1912~1950, and the main threatening factors were area loss, fragmentation and quality descending of the natural habitats. The large and middle mammals also have been threatened heavily in 1950-present, and the main threatening factors are the area loss and fragmentation of the natural habitats and hunting. The area loss, fragmentation and quality descending of the natural habitats have haportant influences on the large and middle mammals extinction. The area loss and fragmentation of the natural habitats and hunting are mainly resPOnsible for endanging, distribution reducing and Population declining of the large and middle mammals. The social, political, economical factors and so on determine the rate of natural habitat area loss, fragmentation and quality changes and hunting level.

威胁舟山群岛大中型兽的主要因素是人为活动对自然栖息地造成的面积损失,破碎,质量下降和捕杀。自然栖息地面积已损失了56.3%,自然栖息地破碎成许多碎片,破碎程度在加深,而自然栖息地质量在1912~1950年间严重下降。大中型兽受威胁历史可分为三个阶段,1912年前,大中型兽受威胁较轻;1912~1950年间,大中型兽受到严重威胁,主要威胁因素是自然栖息地面积损失,破碎和森林覆盖率下降;1950年至现在,大中型兽受威胁同样很重,主要威胁因素是自然栖息地面积损失,破碎和捕杀。自然栖息地面积损失,破碎和质量下降对大中型兽绝灭有重要影响。自然栖息地面积损失、破碎和人为捕杀是大中型兽濒危、分布区缩小和数量下降的主要原因。社会,政治,经济等因素决定了自然栖息地面积损失,破碎和质量变化的速率以及捕杀的水平。

They are fragmented into many fragments and their quality is greatly changed. Just for these, and over-hunting, 5 species of mammals are extincted and 3 species of them are going to extinction, the extinction rate being higher than that on the continent closed by. Population growth is the main cause of the disappearance. fragmentation and quality descending of natural habitats...

Owing to the anthropogenic disturbance, the natural habitats on Zhoushan Island, whose area occupies 56. 3% of the total, are disappeared. They are fragmented into many fragments and their quality is greatly changed. Just for these, and over-hunting, 5 species of mammals are extincted and 3 species of them are going to extinction, the extinction rate being higher than that on the continent closed by. Population growth is the main cause of the disappearance. fragmentation and quality descending of natural habitats and the extinction of mammal species. Some countermeasures and their principles for conserving natural habitats and species diversity are discussed in this paper.

舟山岛自然栖息地和物种受到人类活动的强烈干扰.占总面积56.3%的自然栖息地已经消失,自然栖息地已破碎成许多碎片,碎片面积不断变小,碎片数量在增加.自然栖息地的质量发生了很大变化.自然栖息地的易破碎带与其地理特征有关,破碎易发生于被开垦和开发的地带.由于自然栖息地面积损失、破碎、质量下降和过度捕杀,已有5种兽绝灭,3种兽正走向绝灭,绝灭速度高于临近大陆.人口增长是舟山岛自然栖息地损失、破碎、质量下降和物种绝灭的根本原因.本文还讨论了保护自然栖息地和物种多样性的一些措施和原则.

Using the oligonucleotide probes of LZF-I and F2ZGP 96060801 and the materials of excrements of giant pandas,we have obtained an ideal result on determining the numbers and families of wild giant pandas,and here we will report the methods of determining the number,sexual distinction,family and the structure of age of wild giant panda′s population by means of DNA fingerprinting and PCR and extracting DNA from the excrements of wild giant pandas,and we hope it can solve the problems of determining giant panda′s number of Nature Reserve,the distribution of individuals,the quality of Nature Reserve and the developing trend of Nature Reserve.

作者应用寡核苷酸基因LZF-I和F2ZGP96060801探针,对野生大熊猫粪便样品材料作DNA指纹图分析,确认大熊猫野生种群的个体数量和家系,获得了满意的结果。文章还介绍了在不同自然保护区、山系或行政区域内,大面积上作大熊猫的种群数量调查采用的方法:A在已知大约数量时,则以1∶5采集粪便样品为宜;B在未知数量及密度时,则以面积和路线法布点,采集粪样,避免遗漏,影响真实的种群个体确切数量;C利用空白地形图标注粪样编号,用以核对大熊猫的数量、家系、领域以及每只个体的性别与大致年龄结构,便于评估大熊猫的数量、分布、栖息地的质量与发展趋势,有利于制定保护管理规划,更好地保护大熊猫物种。本法突破了现有陆生哺乳动物数量调查方法,并具有推广和应用价值。
