为了厘清中国近30 a来植被生长趋势及其对不同环境变化的响应,使用了3套长时间序列遥感叶面积指数(Leaf area index,LAI)数据集以及8套生态系统模型,对LAI变化趋势从总量、空间分布以及不同植被类型进行了分析与归因。总量上,1982~2015年遥感观测的LAI趋势(9.8×10^-3m^2/m^2·a)高于生态系统模型模拟的趋势(4.2×10^-3m^2/m^2·a),大气二氧化碳浓度上升是主要驱动因素(3.5×10^-3m^2/m^2·a);遥感观测到全国79.5%的区域LAI都呈现显著增长的趋势,而生态系统模型模拟LAI的增长面积占比为33.1%;除草地外,生态系统模型低估了其他植被类型的LAI变化趋势。模型对降雨变化的响应过于敏感以及对人为活动模拟能力不足是模型模拟中国LAI变化趋势不确定性的重要来源。本研究定量分析了近30 a中国各种植被变化情况及其驱动因子,并对模型低估中国植被生长进行了解释,为后续中国地区植被相关研究提供了参考。

OCEANOLOGIA ET LIMNOLOGIA SINICA is sponsored by the Chinese Society forDeeanology and Linmology and pubished by Science Press (Beijing). Its pubication commenced in1957. It is one of the leading academic journals in China; it is also intemationally *** ET LIMNOLOGIA SINICA is a multi-disciplinary academic journal in thefield of oceanology and limnology. The first Chief Editor was Professor ZENG Cheng-kui (C KTseng), a famous marine algologist who is a Member of the Chinese Academy of Sciences (CAS)and a Fellow of the Third Worid Academy of Sciences. The second Chief Editor was Professor LIURui-yu (J Y Liu), a famous marine biologist who is a Member of CAS and a member of theNational Committee of China Association for Science and Technology. Professor QIN Yun- shan, afamous marine geologist and Member of the CAS, and President of the Council of Chnese Societyfor oceanology and Limnology, is the present Chief Editor. The present Associate Editors arewell-known scientists among whom are Professors LIU Jian-kang (C K Liu) and WEN Sheng-chang(S C Wen), both Members of CAS, Professor ZHOU Ming-jiang, Director of the Institute ofOceanology of CAS, Professor QI Yu-zao, Director of the Institute of Hydrobiology of JinanUniversity and Professor WANG Ying, Director of State Pilot Laboratory of Coast & IslandExploitation, and the Dean, School of Geoscience, Nanjing *** topics of the journal cover hydrology, meteorology, physics, chemistry, geology,geophysics, aquatic environmental science, biology and their branches applied to the earth’shydrosphere and instrumntation. The journal consists of a number of sections including ResearchPapers, Notes, Reviews, Discussion, New Techniques, Book Reviews, Scientific News, andScientists’s *** on the achievements which have a close relationship with the national economic growth,or present new academic viewpoints, will have a priority to be published. Paprs of foreign scientistswill be welcome.
