The Systematic Diagnoses and Analysis of the Eco-vulnerability in Daqinggou National Natural Reserve

大青沟自然保护区生态脆弱性系统诊断与分析(英文)

[Objective] The aim is to conduct systematic diagnoses on the eco-vulnerability in Daqinggou National Natural Reserve. [Method] A kind of ＂problem pile＂ is proposed about 58 interrelated problems of ecological vulnerability by field survey and questionnaires and a ladder diagram of interrelations among the problems is established. The root problems, basic problems, core problems, interrelation and solving approaches are proposed, as well. [Result] It can be concluded from system diagnosis that fragile ecosystem of the Reserve can be observed from poor disasterresistibility, lower species diffusivity, lower system metabolism and poor system restorability. According to system diagnoses, management planning and control subsystem is key for protection of system vulnerability and solving different problems in process-oriented system. Conservation of the Reserve and ecological education on tourists are indispensible. It can be concluded from diagnoses that plant updating, evolution and ill growth in the Reserve are the focus of the vulnerable ecosystem, which influence species diffusivity, system metabolism and restorability and constitute central nodes of process-oriented and effect-oriented subsystems. [Conclusion] The research provides references for solving vulnerability issues of conservation and tourism management in Daqinggou National Nature Reserve.

[目的]对内蒙古大青沟国家级自然保护区生态脆弱性进行诊断分析。[方法]通过样地调查、问卷调查,利用系统诊断技术,针对影响该保护区脆弱性的58个相互关联的问题组成的"问题堆",构建了问题间影响关系层次递阶结构图,使"问题堆"层次化、结构化和模块化,确诊了影响该保护区脆弱性的主要"病根"问题、基本问题、核心问题及问题间影响关系和解决途径。[结果]系统诊断查明,该保护区生态系统脆弱性程度高主要表现为抵抗灾害性能差、物种扩散能力弱、系统生产代谢能力低、系统可恢复性能差等四方面。系统诊断确诊该保护区的规划管理控制子系统中的问题是控制保护区脆弱性的根子层问题,是解决控制对象过程子系统中各个问题的关键,其中,景区保育力度和游客生态教育是解决保护区生态脆弱问题的基本点。系统诊断表明,保护区植被的更新、演替和生长不良是该脆弱生态系统的中心问题,它影响系统脆弱性的物种扩散能力、系统生产代谢能力和系统可恢复性能等三方面,它是过程子系统和效果子系统的中心节点。[结论]该研究为大青沟保护区保育经营和旅游管理解决脆弱性问题提供决策参考依据。
