摘 要 为掌握云南宝台山国家森林公园的森林资源特点,并为制定森林公园的森林资源保护与利用规划提供依据,对该公园2019年森林资源监测数据进行了分析。结果表明:该森林公园林地面积占公园总面积的99.4%,森林覆盖率高达90.50%。林地以有林地为主,面积占比为90.9%。森林起源以天然为主,面积占比为77.8%;人工起源为辅。优势树种以栎类为主,面积占比为45.9%;其次为云南松林,面积占24.1%;再次为核桃林,面积占17.7%。栎类的蓄积量超过总蓄积量的一半,达51.4%;其次为云南松;再次为栲类。森林的龄组以中龄林为主,面积占比为55.2%;幼龄林的面积比例过小。

Abstract In order to grasp the characteristics of forest resources of Baotai Mountain National Forest Park in Yunnan Province,and provide the basis for formulating the forest resources protection and utilization planning of the forest park,the forest resources monitoring data of the forest park in 2019 were analyzed.Result shows that: the forest park is rich in woodland resources,the woodland area accounts for 99.4% of the total land area,and the forest coverage rate is as high as 90.50%. The woodland is mainly woodland,accounting for 90.9%. The origin of forest is mainly natural,accounting for 77.8%,supplemented by artificial origin. The dominant tree species are Quercus acutissima,accounting for 45.9%,followed by Pinus yunnanensis,accounting for 24.1%;the second is Juglans regia,accounting for 17.7%. Quercus acutissima accounted for 51.4% of the total stock,followed by Pinus yunnanensis & Castanopsis fargesii;the age group of forest was mainly middle-aged forest,accounting for 55.2%,but the area proportion of young forest is too small.

森林公園是充分发挥森林功能,特别是森林生态系统服务功能的主要载体,也是森林旅游事业发展最重要的阵地[1]。世界上第一个国家森林公园为黄石公园,建于1872年;而我国的森林公园建设起步较晚,直到20世纪80年代初,研究者才涉足旅游生态学的研究[2]。森林是陆地生态系统的主体,作为自然资源载体和环境保护、生态建设的对象,具有较高的生态效益、经济效益和社会效益,特别是在防风固沙、水土保持、水源涵养、调节气候等方面发挥着重要作用[3-6]。云南宝台山国家森林公园所在区域位于澜沧江大断裂带东侧,山峦重叠,立体气候明显,孕育了大面积的常绿阔叶林及针叶林,生物资源丰富,自然景观优美,加之园内有金光寺、古墓等丰富的人为景观,总体上该森林公园具有较高的社会、经济及生态效益。……
