摘要
绿竹(Dendrocalamopsis oldhami)作为一种优良栽培竹种,不仅能在生物固碳、涵养水源、保持水土等方面产生巨大的生态效益,还能通过集约化经营获得可观的经济效益。为克服引种工作的盲目性,提高引种成功率,以引种气候相似论作为理论依据,利用基于欧几里得距离的模糊优先比法,对比分析绿竹原产地福建省漳州市和引种地重庆市荣昌区、四川省营山县、长宁县的气候差异性,总结绿竹引种到川渝低山丘陵区的适应性,以期为绿竹科学引种提供决策方法。结果表明:1)绿竹引种地与原产地气候相似度由高到低的排序为长宁县>荣昌区>营山县;2)绿竹胸径、株高、枝下高、林分总生物量均表现为引种地大于原产地,表明绿竹在川渝地区具有较强的适应性,同时由于自然条件和林分管理措施的差异,绿竹的表型特征及生物量与原产地表现出一定的差异。基于气候因子的模糊相似优先比法能较好的反映原产地和引种地的相似度,在实践中具有一定的指导意义。
Dendrocalamopsis oldhami is an excellent bamboo species cultivated.It can not only generate huge ecological benefits in biological carbon sequestration,water conservation and soil and water conservation,but also produce considerable economic benefits through intensive management.In order to improve the efficiency and success of its introduction,this paper follows the principle of climate similarity for introduction and uses the fuzzy similarity priority ratio based on Euclidean distance,to compare and analyze the climate differences between its origin at Zhangzhou city in Fujian province and the introducing areas at Rongchang District of Chongqing municipality and Yingshan and Changning counties in Sichuan province,summarize the adaptability of introduced D.oldhami to the low hilly areas of Sichuan and Chongqing,with the aim to provide the support for the decision-makings for science-based introduction of D.oldhami.The results show that:1)The climate similarity between the introducing area and the origin ranks from high to low as Changning county>Rongchang district>Yingshan county;and 2)D.oldhami in the introducing areas has better performances in DBH,plant height,branch height and total biomass than in the origin place,indicating that D.oldhami has strong adaptability in Sichuan and Chongqing.At the same time,due to the differences in natural conditions and stand management measures,D.oldhami in the introducing areas show differences in phenotypic characteristics and biomass from those in the origin place.The fuzzy similarity priority ratio method based on climate factors can better reflect the similarity of origin place and introducing areas,which has certain guiding significance in practices.
