Growth Adaptability of Dendrocalamopsis oldhami Introduced in Hilly Areas of Sichuan and Chongqing
摘要
Abstract
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.关键词
