Seminar on Nanling and Dongjiang Expedition and Research Collaboration

2022-10-25 Jing Li

On October 21, we had a seminar with researchers from Research Institute of Tropical Forestry (RITF) of Chinese Academy of Forestry (林科院热林所), School of Geography and Planning of SUN YAT-SEN University (中山大学地理规划学院) and South China Botanical Garden of Chinese Academy of Sciences (中科院植物园). This seminar mainly discussed：1) the analysis scheme of Nanling tree-ring samples acquired from Professor Wang Xu (王旭), RITF; 2) the water and sediment sampling strategy in Dongjiang area; 3) the cooperative cultivation of students with Professor Zhou Guangyi (周光益), SUN YAT-SEN University.

Many great ideas have been produced during this meeting, so fantastic! In the evening, we had a nice party.

Initiating the Dongjiang Campaign of the GeoBBC Program

2022-08-11 Gan Zhang

On August 10-11, Xiaofei, Shizhen, Li Jun and Zhang Gan joined with a group from SYSU led by professor Chen Jianyao (陈建耀）to visit Heyuan Hydrology Station (河源水文站）. This denotes a kick-off of our Dongjiang （东江） campaign dedicated to the NSFC Major Program ‘Geochemical Behaviours and Environmental Effect of Black Carbon (BC) Substances ‘ (The GeoBBC). By taking Dongjiang catchment as the research venue, we are hoping to illustrate a ‘regional’ picture of BC from the river source and the Pearl River estuary.

The visit, kindly arranged by Professor Chen, came out to be very successful, owing to his and SYSU’s strong influence on the Guangdong Hydrology Centre (广东省水文中心）and its branch Huizhou Centre (惠州分中心）to which the Station is affiliated. We had extensive discussions with the key staffs of Heyuan Station headed by Mr Tian Zhaowei (田兆伟）. Zhaowei and two of his colleagues Ms Chen and Ms Zhang Di are very professional, knowing Dongjiang in great details. Zhang Di, who obtained her MSc with Professor Chen in SYSU, introduced to us the whole picture of the hydrology stations across the Heyuan Section of Dongjiang. It seems that our Dongjiang campaign of the GeoBBC Program could be carried out as planned, with the expected strong support from Mr Tian and his teem.

After the official visit to Heyuan Station, our team was guided by Zhaowei to visit the Xinfengjiang Reservoir and had opportunity to discuss more with professionals there. We were also able to see inside the dam of the XFJ Hydroelectric Power Plant, and the beautiful scenery of the reservoir which is the second largest in China!

In the evening, Mr Zhou who is the head of the Huizhou Branch Centre of Guangdong Hydrology Centre joined us to ascertain kindly his strong support to our GeoBBC-Dongjiang Campaign.

Group visit to Inst Tropical Forestry

2022-07-23 Gan Zhang

On July 21, a group of us including 时真、李静、广财、扬之 paid a half-day visit to Research Institute of Tropical Forestry (RITF) of Chinese Academy of Forestry. RITF is located within 15 minutes away from our institute. We had a quite formal meeting between the SKLOG people and the 南岭北江源生态实验站. Professors We Zhongmin (吴仲民）and Zhou Guangyi (周光益）has been my long time friends. Guangyi gave a detailed introduction of their field facilities across Nanling and their research on the response of forestry ecosystem on climate abnormalities. I gave a talk introducing organic geochemistry and SKLOG . The two sides then had plenty discussion on potential collaborations. I summarized the possibilities as: i) tree rings for¹⁴CO₂; ii) sediment records of historical cold/frozen events and ecosystem response; 3) forestry breath of ¹⁴CO₂; and 4) BC/DBC in fired forest ecosystems in Nanling. We had a lot of drink after the fruitful discussion which last almost 3 hours. Li Jing would be very happy to receive a very precious gift from Professor Wang Xu of RIFT which are preserved tree rings of Guangdong Pine collected from each 3 altitudes from the South and the North aspectes of Nanling! Happy life and enjoyable gathering!

PS: On July 5-8, invited by Zhongmin, I had opportunity to go with a group of experts to the RIFT Nanling Observatory facilities across the mountains. I had a deep impression on the trip and the facilities; and was figuring ideas in mind for potential collaborations/further explores. Now it is clear. I wrote a Ci poetry (词）recording the great trip, below, with many nice poctures in the field.

【浣溪沙南岭记行】

其一
雨后江山肆意骄，白烟恋翠瀑声潮。轻车六月、路迢遥。
绿谷西瑶何所见？得参样地九方坳。层流渗漏、计厘毫。
其二
武水源流莽岭峤，分湘界粤入云霄。松杉针铁、竞粗豪。
百里平湖舒两岸，浊溪润草粉蝶娆。红军故事、乐昌谣。
其三
青嶂山青野草茅，玲珑铁塔过树梢，精心适配、水林交。
迤逦闲心说笑语，江山如画逝流韶，烧鹅就酒、酹滔滔。

Prof Wang Xu (王旭) transferred the precious tree ring samples from Nanling (South and North aspects, each at 3 elevations, from ca. 800-1500 masl) to Li Jing.
