摘要
以汕头市中小水库水源林为研究对象,全面踏查区域内水源林的阔叶树种种类和主要森林群落类型;选择该区域林分形成时间较长、群落特征明显、建群树种以阔叶树种为主的林分设立标准地进行调查,根据调查中出现的阔叶树种、主要群落类型的树种组成和结构功能、造林试验和有关文献资料推荐的适宜该区域造林的树种等综合因素,提出了台湾相思等18种中小水库水源林优化的适生树种;以现有森林群落的评价选优为基础,根据主要森林群落的结构、功能分析数据筛选了台湾相思林等5个林分优化配置模式。为特定区域的林分经营提供一套具有科学依据、实用价值高的技术应用方案。
Taking the water conservation forest in the medium-small reservoirs in Shantou as research object, hardwood species and main forest community type of water conservation forest were investigated. Establishing sample plot to investigate forest stand which have longer formation time, obvious community character and dominant species based mainly on hardwood species. Base on the following comprehensive factors, appearance of hardwood species, structure and function of tree species composition in main community, suitable species in this region commended by afforestation experiment and relative document material, etc. Eighteen optimal adaptive hardwood spe- cies such as Acacia confusa were brought forward. Base of the optimizing evaluation of present forest community, five optimal allocation models of forest stand such as Acacia confuse which according to the analysis data of the structure and function of main forest community were selected. Then a technology application scheme which is scientitle and practical for forest stand management in specific region was provided.
