Subtropical Plant Science 深圳市梧桐山风景区杜鹃花科资源及其 保育现状分析 景慧娟，王定跃 (深圳市梧桐山风景区管理处，广东 深圳 518004) 摘 要：深圳市梧桐山风景区杜鹃花科植物种类少，仅 4 种，分别为杜鹃属的毛棉杜鹃 Rhododendron moulmainense 、丁香杜鹃R. farrerae 、映山红R. simsii 和吊钟属的吊钟花 Enkianthus quinqueflorus ，但4 种杜鹃 花科植物资源储量丰富，形成独特的杜鹃林。在自然条件下，杜鹃林中杜鹃花科植物种群优势度处于退化状态， 生长状况较差。自 2006 年以来，梧桐山风景区分析杜鹃种群退化原因，对其资源进行保育研究，通过对强势 乔木进行间伐、修枝等措施，改善目的树种小生境；采取施肥等复壮措施，改善杜鹃资源生长状况；利用人工 繁殖，增加种苗数量；加强病虫害防治等保育措施取得成效，营造了一批杜鹃生态景观林。建议对梧桐山杜鹃 资源遵循保护大环境，改善小生境的原则持续进行人工抚育，并建立完善的生态景观林监测与管理信息系统。 关键词：杜鹃花科；保育；生态景观林；梧桐山 Doi: 10.3969/j.issn.1009-7791.2018.01.009 中图分类号：S718.54 文献标识码：A 文章编号：1009-7791(2018)01-0043-05 The Status Analysis on Conservation of Ericaceae Species in Wutong Mountain National Park, Shenzhen JING Hui-juan, WANG Ding-yue (Administrative Office of Wutong Mountain National Park, Shenzhen 518004, Guangdong China) Abstract: There were 4 species of Ericaceae in Wutong Mountain National Park, Rhododendron moulmainense, R. farrerae, R. simsii, and Enkianthus quinqueflorus . Wutong Mountain was rich in resources of azalea plants, and had unique Ericaceae species forest. But under natural conditions, the dominant species of Ericaceae was in degraded state, and the landscape effect was poor. Conservation of Ericaceae species resources were carried out since 2006. The intermediate cuttings and pruning for other dominant trees, applying fertilization management, artificial breeding, and reinforce the prevention of plant diseases and insect pests were effective measures to tending Ericaceae specie
