摘　　要：杉木作为我国目前十分具有价值的一个树种,其主要被种植在一些南方城市,并且具备用途广、产量高、生长速度快等优点,因此其也成为了广东省的速丰林造林最主要的树种。根据调查研究可知,杉木占据广东省人工林面积一半以上。而随着我国经济的飞速发展,通过大里的植树造林,使得林木数量得到显著提升。表面看,对于天然林的保护措施已经得到一定的推进,但其实这种模式已经很难满足在可持续发展背景下对林木所提出的需求。结合广东省连山林场的实际情况,为杉木日后实现速丰林目标提供技术支持与参考依据。Cunninghamia lanceolata is of great value.It is mainly planted in southern China.It has the advantages of wide use,high yield and fast growth.Therefore,it has become the main tree species of fast-growing and high-yield afforestation in Guangdong Province.According to the investigation,Cunninghamia lanceolata occupies more than half of the plantation area in Guangdong Province.With the rapid development of China’s economy,the protection measures for some natural forests have been further promoted,and the output of trees has been ensured by increasing the number of trees.However,this model has been difficult to meet the needs of forest production in the context of sustainable development.Based on the actual situation of Lianshan Forest Farm in Guangdong Province,this paper will provide technical support and reference for realizing the goal of fast-growing forest.
