东莞市自然保护区保护评估体系构建与应用

Construction and application on the protection and evaluation system of Dongguan nature reserve

自然保护区是我国重要的生态屏障,充分发挥自然保护区的保护成效是实现生物多样性保护目标的关键,开展保护成效评估对促进自然保护区的有效管理和宏观决策具有重要意义。文章以东莞市6个自然保护区为研究对象,基于现有研究成果和技术标准规范,采用层次分析法构建了包括3个基准层、10个因素层和28个指标层的评估体系和综合评估模型,对东莞市自然保护区的保护成效进行评估。结果表明,东莞市16.67%的自然保护区评估为A级,66.66%的自然保护区评估为B级,16.67%的自然保护区评估为C级;东莞市的自然保护区网络对区内自然生境景观的保护效益显著,减缓了边界范围内景观破碎化趋势。该研究可为地市级区域内的自然保护区保护成效评价方法的探索提供参考,研究结果可为地市级区域内自然保护区保护成效提升与优化调整提供科学支撑。

Natural reserves are important ecological barriers in China,and fully utilizing the protection effectiveness of natural reserves is the key to achieving biodiversity conservation goals.It was great significance for promoting effective management and macro decision-making of natural reserves with conducting protection effectiveness evaluation.Based on existing research results and technical standards and specifications,it was constructed an evaluation system consisting of 3 benchmark layers,10 factor layers,and 28 indicator layers.The weight values of the indicators were determined using Analytic Hierarchy Process and a comprehensive evaluation model was constructed.It was evaluated the effectiveness of natural conservation in six nature reserves in Dongguan City as the research object.The results showed that,16.67%of the natural reserves in Dongguan City were classified as Grade A,66.66%as Grade B,and 16.67%as Grade C.The network of natural reserves has a significant protective effect on the natural habitat landscape within the area,slowing down the trend of landscape fragmentation within the boundary.This study can provide reference for the exploration of evaluation methods for the protection effectiveness of nature reserves,and the research results can provide scientific support for the improvement and optimization adjustment of the effectiveness of regional scale nature reserves.
