顾渚山自然保护区生态质量评价研究

Ecological Quality Evaluation of Guzhushan Nature Reserve

本文以顾渚山自然保护区为研究对象,采用样方调查法、样线调查法等方法对保护区内的动植物进行调查,参照《自然保护区自然生态质量评价技术规程(LY/T1813—2009)》中野生植物类型自然保护区相关生态评价指标,以典型性、稀有性、自然性、面积适宜性、脆弱性和人为活动强度等影响因子构建评价体系;采用层次分析法对保护区的生态质量进行评价分析。研究结果显示,顾渚山自然保护区在物种典型性、物种濒危程度及地区分布、生境状况、自然度、生态系统稳定性、资源开发利用情况等方面经评价分析后,各分项指标得分较低,评价累计得分37.7,这表明该自然保护区的生态质量较差。顾渚山自然保护区生态质量总体情况不太乐观,虽然保护物种的生活力很强,但保护区的生态保护措施不到位,整体生态系统稳定性不强,资源开发利用情况和周边地区开发状况对自然资源存在潜在威胁。

In this paper,Guzhushan Nature Reserve was taken as the research object,and the fauna and flora in the reserve were investigated using the method of sample plot survey and line transect survey,referring to the ecological evaluation indexes of wild plant type nature reserve in the Technical Regulations for Evaluation of Natural Ecological Quality of Nature Reserve(LY/T1813—2009).The ecological quality of the protected area was evaluated by analytic hierarchy process based on the influence factors of typicality,rarity,naturalness,suitability of area,vulnerability and intensity of human activities.After the evaluation and analysis of the influence factors of species typicality,species endangerment degree and regional distribution,habitat condition,naturalness,ecosystem stability,resource development and utilization,the scores of each sub-index are low,and the evaluation score is 37.7,indicating that the ecological quality of the nature reserve is poor.The overall situation of ecological quality in Guzhushan Nature Reserve is not optimistic.Although the protected species are strong,the ecological protection measures in the reserve are not in place,the overall stability of the ecosystem is not strong,and the development and utilization of resources and surrounding areas have potential threats to the natural resources.
