摘要
基于层次分析法和模糊综合评判,以GIS作为数据处理手段,建立生态承载力综合评价模型,评判宝天曼自然保护区受人类活动干扰最强烈的旅游资源——植被景观生态系统的生态承载力和生态荷载,结果得到宝天曼自然保护区处于潜在超载状态,生态环境呈现脆弱性,表明保护区植被景观的生态系统没有本质的变化,但存在一定的"量"的变化。
Based on analytical hierarchy process and fuzzy comprehensive evaluation,applying GIS as the data processing platform,a comprehensive evaluation model was established to judge ecological carrying capacity in Baotianman Nature Reserve in Funiu Mountain,Henan Province,China,which was seriously interfered by tourist activities.It was found out that the reserve was in the state of potential overload,ecological environment exhibited vulnerability,indicating that the ecosystem of vegetation landscape did not essentially deteriorated.However,some ＂quantitative＂ deterioration existed.
