Abstract: Density index of Rhododendron moulmainense aesthetic forest was studied. Results showed that R. moulmainense had sufficient growth space when the density of upper tree was 250—350 plants·hm-2. According to standard survey, the lower density of R. moulmainense, the better its growth. Considering the continuity of ecological landscape, and avoiding large forest window, the lowest density of R. moulmainense was confirmed by crown coefficient method. The lowest density of R. moulmainense in Wanhuaping was 437 plants·hm-2. The lowest density of Xiaowutong was 733 plants·hm-2.

Key words: Rhododendron moulmainense, aesthetic forest, density control, crown coefficient method

摘要： 通过标准地调查，对深圳市梧桐山毛棉杜鹃Rhododendron moulmainense风景林林分密度进行研究。结果显示，当上层乔木密度为250～350株·hm-2时，毛棉杜鹃拥有充足的生长空间，个体生长达到最优。在标准地内，毛棉杜鹃密度越低，长势越好。为保证毛棉杜鹃具有充足的生长空间，又兼顾生态景观林的景观连续性，避免出现较大的林窗，通过树冠系数法得到万花屏地区毛棉杜鹃最低密度437株·hm-2；小梧桐地区最低密度733株·hm-2。
