云南松具有较广的生态适应性和天然更新能力强的特点,但其天然更新效果是受各种自然因素所支配。在保证种源的条件下,自然因素是影响天然更新的主导因素。从大量调查材料整理分析看:海拨1300米以下地段更新困难,海拨升高,更新效果越好,过高也会影响更新;湿度过大不利于更新;阳坡、半阳坡的云南松天然更新效果优于阴坡;草本植物盖度以30—40％有利于天然更新;林冠下只见云南松幼苗,而不是幼树,不能更新成林;采伐跡地上保留一定的母树,天然更新良好,跡地清理比未清理的效果要好。同时,本文也对云南松人工林作了研究,根据立地条件和生长情况,对云南松人工林划了五个类型。此外还对云南松的演替规律作了初步探讨,为今后发展云南松林提供参考。

云南松林是我国西南地区一个特殊的松林类型。其分布范围较局限,分布区以云南高原为分布中心,仅限于云贵高原西部地区。由于云南松的生态适应性宽广,在分布区内形成云南松林的优势复盖和集中连片分布。但分布地区所处生境条件复杂,本文根据不同的水热组合状况,将云南松林划分为云南高原中部和金沙江中游、东南部南盘江中上游、西南部元江上游和怒江中游,以及西北部金沙江上游和澜沧江上游等四个云南松林区。依据生态环境的差异和相似性,将林内的伴生树种和主要森林植被相近似的林分,归纳组合了十个森林亚类型,以利于对云南松林的经营管理。

为了探究不同浓度赤霉素对去顶后云南松(pinus yunnanensis)生长及生物量积累、分配的影响,揭示云南松生物量分配特征及各器官间相对生长关系,为去顶后云南松激素促萌提供理论依据,以1年生去顶云南松苗木为试验对象,设置不同的赤霉素浓度进行处理。分析不同处理下云南松生长及生物量积累、分配的影响和云南松各个器官的异速生长关系。结果表明,不同处理对去顶后云南松地径生长有显著影响,对生物量积累与投资同样存在显著差异。叶与侧根生物量呈不显著的正相关,萌条和叶生物量呈显著负相关,此外其余器官两两之间呈正相关关系,各个器官之间存在等速或异速生长关系。赤霉素浓度300 mg/L有利于去顶后云南松地径的生长,同时萌条生物量和地上生物量积累为最高,萌条生物量分配比为最高。去顶后云南松各器官生物量分配积累存在着相关性,共同促进或者抵抗,与器官相对生长关系共同响应赤霉素的添加。
