大型固定样地(简称大样地)能够为人们系统地了解生物多样性、群落动态、物种共存机制等问题提供翔实、充分、长期的数据(马克平,2008;兰国玉,2007).因此,通过建立大型固定样地开展森林生态系统定位研究越来越受到重视(叶万辉等,2008;张建侯等,1994;Condit,1998).1980年,Stephen Hubbell和Robin Foster在巴拿马的Barro Colorado岛建立了第1个大型监测样地,美国Smithonian研究院热带森林研究所(Smithonian Tropical Research Institute)热带森林科学研究中心(Center for Tropical Forest Science,CTFS)建立的热带森林监测网络则是大型固定样地最优秀的代表之一.大样地的建设有效监测了物种的时空分布模式,为研究物种多样性的维持机制、物种空间分布格局、群落动态、自然干扰等提供了重要的研究平台,并取得了大量成果(兰国玉,2007).%Based on former work, Xinjiang Tianshan forest ecology station and Xinjiang University, set up a large scale permanent plot in northern Picea schrenkiana var. Tianschanica forest covering 8 hm and then all-around investigation on the plot have been carried out favourably in order to make the long-term observation and research. On the base of its foundation and investigation, the three-dimension visualization analysis and management of the basic information of the plot have been realized based on CIS. This study work is essential and useful for the long time management and maintenance, the refreshment and analysis of basic information and investigation data, the detailed illustration of forest community movements of this large scale permanent plot. It also provides a beneficial case for same work about forest ecology.
