生态建设背景下的宁夏生物多样性保护问题研究

宁夏地处西北半干旱地区，生物多样性组成简单，但同时又具有很强的过渡性，在物种的区系构成上也具有复杂性．由于生态环境破坏、生物资源过度利用、土地资源不合理开发、建设性破坏、对生物多样性认识不足以及保护措施不利等问题，严重妨碍了宁夏生物多样性的保护工作．在目前实施生态建设工程的背景下，提出了保护生物多样性的相应措施：实施生物多样性保护战略；加强基础研究；强化自然保护区建设；推行生态旅游战略；加强湿地保护．     

温州滩涂湿地的现状、问题及保护对策

温州滩涂湿地的现状不容乐观,生态问题日益突出,面临的主要问题是：人类干扰不断加剧,且缺乏有效的监测手段和管理措施,使得鸟类栖息地破坏严重,滩涂湿地污染加剧;外来种互花米草的入侵也对滩涂湿地的生物多样性造成了严重的干扰和影响。针对温州滩涂湿地存在的问题,提出了相应的保护和恢复对策：不断健全湿地保护的法律法规;科学围垦;加强对外来入侵种的监测和控制;加快滩涂湿地自然保护区的建设;严格管理滩涂湿地,加强污染控制,开展生态治理,增强保护意识等。以切实保护温州滩涂湿地生物群落的多样性,持续发挥其生态服务功能。     

A Study on Forest Species Diversity and Its Ecological Service Function in the Plateau Area of Western Sichuan

This paper presents a study on species diversity and its ecological service function in the plateau area in western Sichuan. The results show that species diversity in the plantations on the cutover land has a tendency to increase and that its ecological service function is to be improved with stand age growing. The species diversity in forest communities is also gradually increased on different succession stage till reaching a climax level. But the species diversity in the climax community is slightly decreased before it reaches a relatively constant status. Ecological service function of diversity is gradually strengthened with the progress of succession. In addition, species diversity in a stand in a similar site and at a same age differs among forest types. Species diversity index within a coniferous and broad-leaved mixed forest is larger than that within a coniferous forest. Meanwhile, species diversity enriches as the tree density increases.     

On bio-diversity, complexity of M-CSF and its receptor

With the development of science, the methods and the views of scientific research changed from analyses to syntheses. Recently, more attention has been paid to bio-diversity and complexity. According to the study on M-CSF and its receptor for years, the author suggests that, the multi-level of bio-diversity also appears at the bio-macromolecular level. Probability of bio-diversity is one of the bases for bio-complexity. Cellular sociology and topobiology are important aspects in bio-complexity, and should be developed. If taking Chinese traditional medicine together with the advantage from Reductionism, joining the study on complexity, Chinese scientist would make a chair in the international scientific society.     

深圳福田红树林害虫及其发生原因

报道1994和1999年福田红树林害虫，其它昆虫及蜘蛛的调查结果，1994年在红树林采到昆虫96种及蜘蛛7种，其中天敌昆虫37种，占已知种类的35．8％；1999年采用昆虫53种及蜘蛛5种，其中天敌昆虫13种，占已知种类24％，对地林造成为害和具有潜在危害的种类也有所增加，Shannon-Wiener多样性指数（H），均匀度指数（J）和丰富度指数分别为：H1994＝2．47，H1999＝1．64，J1994＝0．54，J1999＝0．42，D1994＝16．1，D1999＝9．37，分析结果显示，1999年红树林生态环境比1994年急剧恶化，这是红树林害虫发生的根本原因。

Age-Structure and Dynamic of Dominant Population of Castanopsis carlesii Community in Dujiangyan City, Sichuan, China

It analyses the Castanopsis carlesii, Camellia oleifera and Symplocos laurina populations‘ status and role in the Castanop.sis carlesii community basing on the study on the dominant population size structure, survival curve and dynamic. It reveals the Castanopsis carlesi population acts as a main role in the community which maintains the stabilization and renovation of the community. The populations of Camellia oleifera and Symplocos laurina act as a secondary position. The development and succession dynamics of dominant populations is also discussed. The management method is preliminary draw nout which offers a theoretical basis for the evergreen broad-leaved forest restoration and reconstruction in the lower hilly of the west edge of the Sichuan basin.     

以人为本与保持生命多样化的精髓

当代环境危机使人类重新审视人类在自然界中的位置,从消极被动地适应自然到盲目乐观地征服自然,再到今天积极地协调人与自然的关系,表明人文视野的拓展影响着人与自然关系的重新定位.事实上,走出环境危机离不开人,以人类认识世界并掌握世界规律的文明为依据,保持生命多样化,是人类文化的必然归宿.
