Therefore, the chiru attracted a lot of attentions of the Chinese government, conservation scientists and other conservative organizations in the world.In the present study, 57 chiru individuals were sampled from Arjin Shan Nature Reserve in Xinjiang, Chang Tang Nature Reserve in Tibet and Kekexili Nature Reserve in Qinghai. The present study, based on the analyses of the chiru mitochondrial control region with MEGA, DnaSP and ARLEQUIN programs, investigated into the genetic diversity background, evolutionary history and population relationships and aimed to provide scientific basis for the protection of the chiru.

本研究以采集于新疆阿尔金山自然保护区、西藏羌塘自然保护区和青海可可西里自然保护区的57个藏羚羊个体为研究对象，应用MEGA、DnaSP和ARLEQUIN等分析软件对其线粒体DNA控制环区序列进行分析，以研究当前藏羚羊种群的遗传多样性背景，地理种群关系及其进化历史中种群变化情况，并为藏羚羊的保护工作提供科学依据。

Although theoretical principles have been proposed for designing the nature reserve based on the knowledge of island biological geography, population viability analysis and landscape ecology, they appear unsuitable in practice.

During the first part, investigate the numbers and location of the different nature reserve, and review about its development, discuss the cause about the rapid developmeng about the protection areas of nature around Beijing. During the second part, this paper use the Geographical Information System to analyze the different sight function, plot our distinct function about the protection area of nature around Beijing. In the third part of this paper, the ecology function was special analyzed. This paper picked up several factor about the ecology and establish mathematics model to detect the most rational ecology distribution, bring forward the new constructive, wilder constructive and combination project. In the last parts of the paper, this paper use the Geographical Information System to analyze the different brim about the protection area of nature around Beijing, calculating the p/a and figure coefficient, and bring forward the brim theory for the nature reserve and city system.

在数量布局方面，包括北京周边各个不同级别的保护区的数目、位置分配布局和发展趋势研究，探讨北京市周边自然保护区数目和面积在99年和2000年突然增长的主要原因，以及今后北京自然保护区的发展方向；在景观布局方面，主要根据不同自然保护区的空间和功能的不同，计算延庆县各个自然保护区的景观多样性指数和景观优势度指数，并结合地理信息系统和航片，划分出不同的景观功能区间，以及各个功能区间之间的相互关系；在生态布局方面，综合考察北京周边自然状况，提取多项因子，建立评价模型，计算出各项因子权重，从而对其自然保护区的生态功能布局的合理性进行评价和趋势分析，为本文提出北京市周边自然保护区新建、扩建与合并的方案提供依据；在边缘布局方面，利用边缘效应理论和研究方法，创新提出&边缘类型样块分析法&，提取多个样方并结合地理信息系统，计算p/a比和自然保护区边缘的形状系数，划出自然保护区边缘效应趋势变化图，考察北京周边自然保护区的边缘效应，以及对城市的生态边缘功能。

此外，在自然低温和冷水胁迫下，各省粳稻地方品种的聚类结果总体上与各省品种的地理位置及其耐冷性有密切的联系，而在冷水胁迫下品种的聚类结果与品种地理位置的关系比自然低温下更为密切。

The reason included five aspects:①the effect of physical environment: the open geographical environment and barren soil urge the Greeks to look for development outward while the close geographical environment and advantaged condition for agriculture shaped the Chinese conservative thought and obstructed their steps of going out.②the advancing and blocking of the economic: the frequent trade offered an abundant living supply and open view while the self-sufficient agriculture with restraining trade rigidified the thought.③ the difference in politic institute and situation: the democracy polis of ancient Greece is exclusive in the ancient world. It shaped the atmosphere of freedom, democracy and adversary. While the monarchy in ancient China pursued the "united country" and shaped the atmosphere serving for politic and consolidating thoughts.④the guiding of traditional culture: the Greeks pursued freedom and wisdom and were curious about nature while the Chinese adored ancestor and obeyed the authority and prefer to pragmatism.

出现这种关系的原因本文从以下五点进行分析：①自然环境的影响：古希腊开放的地理环境和贫瘠的土壤种植条件促使古希腊人向外寻求发展，而古代中国封闭的地理环境和优越的农业环境阻碍了中华民族外出的脚步和开放的思维；②经济条件的推动与束缚：工商业发展的农业经济和自给自足的小农经济所创造的物质条件和对思维影响的差别是很大的；③政治制度和政治形势的差异：古希腊民主城邦制在古代世界是独树一帜的，它所营造的自由、民主的氛围和古代中国追求&大一统&的君主专制下为政治服务、思想趋向统一的氛围截然不同；④传统文化的引导：古希腊人在长期的城邦生活和参与海外贸易的生活中形成的开放、自由、对自然充满好奇、追求智慧等民族文化传统与中国保守崇古、讲究实用的文化传统形成了鲜明的对比；⑤思想家本身(来源：A58BC论文网www.abclunwen.com)目的不同：古希腊思想家为了变得智慧而获取知识，享受知识带来的乐趣，而古代中国思想家的一切动机都是为了&成化天下&、&以政裕民&服务。
