摘　　要：我国南方丘陵地带公益林生态空间结构的合理有序是区域安全的保障和经济发展的基础。本研究基于公益林生态系统服务重要性评价和生态环境敏感性评估评价方法识别浙江省淳安县公益林的重要生态源地,分析公益林生态安全空间特征,并提出了相应的保护优化措施。结果表明:①淳安县公益林生态系统服务重要性整体状况良好,其中,高度重要公益林所占比例最大,占全县公益林总面积的41.93%;较重要、中等重要与极重要公益林所占比例相近,分别占全县公益林总面积的17.92%、19.53%与18.27%;一般重要公益林仅占全县公益林总面积的2.35%。②淳安县公益林生态环境敏感性整体状况良好,其中,高度敏感与中等敏感公益林分别占全县公益林总面积的37.28%和31.05%;较敏感和极敏感公益林所占比例差别不大,分别为占全县公益林总面积的17.05%、11.57%。③淳安县公益林生态源地总面积为50160.04 hm2,占研究区总面积的30.13%,生态源地斑块主要分布在千岛湖西北、东北、东南湖区沿岸,围绕千岛湖形成生态屏障。基于以上研究结果,认为生态源地是森林资源保护和城镇开发建设的生态底线,应切实保障现有公益林生态源地资源安全,严格禁止开发利用。The important of ecosystem service and eco-environmental sensitivity of ecological forest in Chun’an,Zhejiang province were analyzed by evaluation.The results showed that ecosystem service importance of ecological forest in Chun’an was great,and the proportion of highly important ecological forest was the largest,accounting for 41.93% of the total area of ecological forest in Chun’an.The proportion of relatively important,medium important and extremely important was similar,17.92%,19.53% and 18.27%,respectively.The general importance forest accounted for only 2.35%.The overall eco-environmental sensitivity of ecological forest in Chun’an was well,and the highly and moderately sensitive accounted for 37.28% and 31.05% of the total one of the county.The proportion of relatively sensitive and extremely sensitive was 17.05% and 11.57%,respectively.The total area of ecological source of ecological forest in Chun’an was 50160.04 ha,accounting for 30.13% of the total one.The fragments of ecological source mainly distributed in the northwest,northeast and southeast of Qiandao Lake,forming an ecological barrier around Qiandao Lake.Suggestions were put forwarded such as the safety of ecological source and no any exploitation.
