摘要
目前对平潭综合实验区(平潭主岛)脆弱性评价方面的研究仅有地下水系统的脆弱性研究,对生态环境方面的脆弱性研究尚未见诸文献中。针对此情况,文章首先从自然因素、人为干扰因素和环境因素3个方面构建了生态环境脆弱性指标体系,然后运用主成分-聚类分析模型对平潭综合实验区的生态环境脆弱性进行分区。脆弱性分区结论为平潭综合实验区总体为中强度脆弱,其中极强脆弱区为白青乡,强度脆弱区为北厝镇和苏澳镇,中度脆弱区为中楼乡、澳前镇和敖东镇,轻度脆弱区为平原镇、潭城镇和流水镇,微脆弱区为芦洋乡。文章从增加防护林的面积和种类、调整优化土地利用结构、开展生态功能区划和生态环境保护规划的编制工作三方面提出了降低研究区域生态环境脆弱性的对策措施。
There is only research about vulnerability of groundwater system in vulnerability evaluation field, while eco- environmental vulnerability research has not yet appeared in any paper in Comprehensive Experimental Area of Pingtan （Pingtan Island）. Thus the paper first constructs eco-environmental vulnerability index system based on natural factors, human-influence factors and environmental factors. The principal .component-cluster analysis model was used for eco- environmental vulnerability partition in Comprehensive Experimental Area of Pingtan. Results showed that most towns in Pingtan Island are moderately intense vulnerable, among which Balqing is pole-intense vulnerable, town of Beicuo and Su＇ao are intensely vulnerable, town of Zhonglou, Aoqian and Aodong are moderately vulnerable, town of Pingyuan, Tancheng and Liushui are mildly vulnerable, and only Luyang town is micro-vulnerable. Finally this paper put forward measures about eco-environmental vulnerability reduction in three ways including increasing shelter-forest. area and kinds, adjusting and optimizing land-use structure, and implementing eco-functional regionalization and eco-environmental protection planning.
