元谋干热河谷桉树人工林内坡柳叶片功能性状的变化
|
摘要
干热河谷是我国西南地区的典型脆弱区,过去开展了种植桉树林为主的植被恢复,但其生态效应评价研究较少。本研究以元谋干热河谷本地典型物种坡柳为研究对象,在人工桉树林和自然群落2个不同类型的群落中,测量了坡柳的比叶面积(SLA)和叶片饱和水分亏缺(WSD)等9项植物功能性状指数以及土壤水分含量的差异。结果表明:(1)WSD、LRWC、LDMC、LMP等功能性状指标以及土壤水分含量都表征出在人工桉树林的生境更加干旱;(2)桉树林下坡柳的LA、LT以及SLA增大,LD减小,这些指标的增大并不利于物种耐受干旱环境。本研究表明,生长于人工桉树林下坡柳的生境更加干旱,且产生了不耐旱的性状,对其生长极其不利。
Dry-hot valley is a typical fragile area in southwestern China.Although vegetation restoration has been carried out in eucalyptus forests in the past,there are few studies on the evaluation of its ecological effects.In this study,a typical native species of Dodonaea viscosain the dry hot valley of Yuanmou was studied.In 2 different Eucalyptus communities which were artificial type and natural type,9 plant functional traits such as the specific leaf area(SLA)and the water saturation deficit(WSD)and the difference in soil water content were measured.The resultsshowed that:(1)Functional traits such as WSD,LRWC,LDMC,LMP,and soil water content all indicated that the habitat of artificial eucalyptus forests was more arid;(2) Under the eucalyptus forest,LA,LT and SLA increased,while LD decreased.These indexes were not conducive for species tolerance to arid environment.This study indicated that the habitat of D.viscosa under artificial Eucalyptus forest was becoming aridand the plant showed a drought-resistant traitwhich is unfavorable for its growth.
