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。

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 species resources. The artificial tending to Ericaceae species resources was a sustained mission, which need to follow the principles of protecting the community ecosystem. Of course, it was necessary to establish a sound ecological landscape forest monitoring and management information system.

Key words: Ericaceae species, conservation, ecological landscape forest, Wutong Mountain
