摘要:
为探明不同类型滨海防护林凋落物量的差异及其对气象因子的响应,以福建长乐大鹤国有防护林场的纹荚相思和湿地松人工林为研究对象,2014—2018年的每个月底调查凋落物量,分析凋落物量月动态及其与气象因子的关系。结果显示:湿地松人工林年平均凋落物量(10.29 t·hm-2·a-1)显著高于纹荚相思(7.21 t·hm-2·a-1),湿地松人工林的凋落物各组分含量大小为叶凋落物>花果凋落物>枝凋落物>其他凋落物>树皮凋落物,纹荚相思人工林的凋落物各组分含量大小为叶凋落物>枝凋落物>其他凋落物>花果凋落物>树皮凋落物,其中,凋落叶为2种人工林凋落物的主要成分,分别占年平均凋落物量的70.00%(纹荚相思)和76.24%(湿地松)。纹荚相思和湿地松人工林凋落物量最高的月份分别为7和8月,1—4月的凋落物量较低。月凋落物量与气象因子的相关性分析表明,2种人工林凋落物量均与平均温度、最高温度、最低温度以及日照时间呈显著正相关(P<0.05)。此外,湿地松人工林凋落物量与极大风速呈极显著正相关(P<0.01)。
Abstract:
The litter production, monthly dynamics of the litter, and effects of meteorological factors on litter production of two evergreen plantations(Acacia aulacocarpa and Pinus elliottii) in Changle Dahe Forest Farm, Fujian Province were investigated at the end of every month from January 2014 to December 2018. The results showed that the annual litter production of P. elliottii and A. aulacocarpa was 10.29 and 7.21 t·hm-2·a-1, respectively, whereas the annual litter production of P. elliottii was significantly higher than that of A. aulacocarpa. The order of litter size of P. elliottii litter was leaf litter> flower and fruit litter> branch litter> other litter> bark litter. The order of component size of A. aulacocarpa litter was leaf litter> branch litter> other litter> flower and fruit litter> bark litter, in which leaf litter was the main component of the two types of artificial forest litter, accounting for 70.00%(A. aulacocarpa) and 76.24%(P. elliottii) of the total litter. The maximum litter production of A. aulacocarpa and P. elliottii occurred in July and August, and the minimum litter production was between January and April. The correlation analysis of the two types of plantation litterfall production and meteorological factors showed that the litter production of the two types of plantations was significantly positively correlated with the average, the highest, the lowest temperature and sunshine duration(P<0.05). In addition, P. elliottii had a very significant positive correlation with extreme wind(P<0.01).
