【摘要】 长沙市麓山景区是中国四大传统红叶观赏胜地之一,枫香是著名的红叶树种,为了保护枫香红叶这一自然景观资源,恢复和营造岳麓山的秋色叶景观,笔者对麓山景区的秋季色叶景观进行了调查和分析研究,有以下几方面:(1)分析外界环境对秋色叶树种的影响,发现秋色叶色彩形成的原因是多方面的,包括内因(遗传)与外因(低温、光照、干旱、空气湿度)等息息相关。(2)秋色叶树种的调查与分类,是本研究的基础重点,据植物学家统计,全区内共有植物174科597属977种,其中有117科403属555种为野生种子植物,几乎具有北温带乔木属的全部典型属。经调查发现,景区内秋叶树种共74种,其中红色的有29种,占秋色叶的41.9%,黄色的有43种,占秋色叶的58.1%。(3)秋色叶景观林的保护和优化整理技术研究,将野外调查与室内分析相结合,分资料收集、外业调查和内业处理3个阶段,调查几十个秋色叶植物群落,其中对具代表性的8个枫香样地进行重点统计与分析。包括:栲树+枫香—尖叶杨桐—三脉叶马兰群落(样方1),苦槠+台湾冬青—石灰花楸—贯众群落(样方2),枫香+榕叶冬青—香楠—稗荩群落(样方3),枫香+越南山龙眼—冬青—淡竹叶群落(样方4),长毛八角枫+枫香—假死柴—杜茎山群落(样方5),香樟+枫香—白花苦灯笼—稗荩群落(样方6),枫香+青冈栎—柘树—苎麻群落(样方7),枫香+飞蛾槭—冬青—杜茎山+树麻群落(样方8)。(4)古枫香林景观保护和优化整理技术研究,麓山景区现有古树307株,主要树种为枫香221株,都有详细的纪录并附有照片,针对古树的现状,对危害古树的生存因素进行详细分析,存在以下问题:①立地条件差;②病虫危害;③树干空洞;④树冠不平衡;⑤风、雷、雪害和雨淞(冰挂)等自然力破坏;⑥人为因素破坏。并提出相应的解决对策:①对景区内古树资源进行全面深入调查,在此基础上进行注册、登记、建档工作;②对古树名木的立地环境及危害生存原因进行分析;③采取科学的技术措施,养护抢救古树名木;④利用现代或相关媒体手段,对古树名木保护工作的重大意义进行宣传教育;⑤制定《岳麓山古树名木管理办法》,实行保护责任制。更多还原
