对武夷山自然保护区星村镇桐木村茅排及观测站附近天然林中3个样地共25个林隙进行调查,探讨了武夷山中亚热带常绿阔叶林林隙动态及自然干扰规律。该天然林林隙形状近似于椭圆形,椭圆的长短轴比率EG和CG有所不同,平均分别为1.36和2.14;扩展林隙(EG)和树冠空隙(CG)在亚热带常绿阔叶林景观中的面积比例分别为80.18%和28.37%,干扰频率分别为1.604%.a-1和0.567%.a-1。林隙干扰返回间隔期约为176 a。EG大小一般变化在140~613 m2左右,平均约为241 m2,大多数CG大小一般都变化在75~467 m2左右,平均约为85.1 m2。林隙一般是在50 a以内形成的,而30~40 a之间形成的林隙最多。大多数林隙是由1~3株形成木创造的,而由1株形成木创造的林隙最多。林隙形成木通过干基折断死亡的形式存在。星村镇桐木村茅排及观测站附近天然林中的林隙主要是由10多个树种创造的,其中不仅有第1层的树种,而且还有第2、3层的树种。最后以林隙动态理论为基础,对武夷山常绿阔叶林的经营管理提出了参考意见。
A total of 25 forest gaps were surveyed in Mao Tong, Tongmu Village, Xingcun Town, Wuyishan Nature Reserve, and the natural forest in Wuyishan. The dynamics and natural disturbances of the gaps in the evergreen broad-leaved forest in Wuyi Mountain were studied. The natural forest gap shape is similar to the oval, the elliptic long and short axis ratio of EG and CG are different, with an average of 1.36 and 2.14; expanding gap (EG) and canopy space (CG) in subtropical evergreen broad-leaved forest landscape In the proportion of the area were 80.18% and 28.37%, the interference frequency was 1.604% .A-1 and 0.567% .A-1. Gap interference return interval is about 176 a. The general variation of EG size is about 140 ~ 613 m2, with an average of about 241 m2. Most of the CG sizes generally vary from 75 to 467 m2 with an average of about 85.1 m2. The gap is generally formed within 50 a, while the gap formed between 30 and 40 a is the largest. Most of the gap is formed by the formation of 1 to 3 wood, but by the formation of a wood to create the most gaps. Gap formation wood exists in the form of death by dry-base breaks. The gaps in natural forests near the pavilions and pavilions in Tongmu Village, Xingcun Town are mainly created by more than 10 tree species, including not only the first tree species but also the second and third tree species. Finally, based on the theory of gap dynamics, this paper puts forward suggestions for the management of evergreen broad-leaved forests in Wuyi Mountain.
