广东大北山国家级森林公园森林景观问题分析及修复技术设计

Analysis of Forest Landscape Problems and Design of Restoration Technology in Dabieshan National Forest Park,Guangdong Province

在系统掌握广东大北山国家级森林公园森林景观现状的基础上,运用《中国森林公园风景资源质量等级评定》(GB/T18005-1999)等方法,对该公园的生物风景资源进行了逐项评价、打分和综合测评,得分为25.1分,仅为理想得分(40分)的62.5%;分析了其病理性问题主要为森林群落生物多样性欠缺、景观基调一般、观赏价值不高;进而提出了对该公园现有的8条公路两侧、总长度为34.33 km的森林景观林带进行生态修复施工设计,以期增加该公园的森林景观多样性,形成生态景观廊道,并指出该设计实施后具有较好的社会效益、生态效益和经济效益,可为广东省1359个自然保护地乃至国内相类似立地的森林景观修复提供借鉴和示范带动作用。

Based on the systematic understanding of the current situation of the forest landscape of the Dabieshan National Forest Park in Guangdong Province,the methods such as the Rating of China Forest Park Landscape Resource Grade Evaluation(GB/T18005-1999)are used to evaluate,score and comprehensively evaluate the biological landscape resources of the park item by item,with a score of 25.1 points,only 62.5%of the ideal score(40 points);The main pathological problems are lack of biodiversity of forest community,general landscape tone and low ornamental value.Furthermore,it is proposed to carry out the ecological restoration construction design for the forest landscape forest belt with a total length of 34.33km on both sides of the eight highways in the park,in order to increase the diversity of the forest landscape,and form the"Two Rings and Four Belts"ecological landscape corridor with red flowers and green leaves,colorful,obvious seasonal patterns and abundant red color.It is expected that the design will have the better social,ecological and economic benefits after the implementation of the design.It can provide reference and demonstration for the forest landscape restoration of 1359 nature reserves in Guangdong Province and even similar sites conditions in China.
