On June 3, 2023, Prof. Pei Xiangjun, Dean of the School of Eco-Environment of Chengdu University of Technology, was invited to give a report titled "Ecological Restoration and Carbon Sinks" in the lecture hall of the Institute of New Concept Sensors and Molecular Materials. Teachers and graduate students of the institute attended the meeting, which was chaired by Prof. Ding Liping.

Prof. Pei has completed the high slopes of 13 hydropower stations such as the Three Gorges on the Yangtze River, Xiluodu on the Jinsha River, and Jinping on the Yalong River, as well as ecological restoration demonstrations in Lhasa's Gongga Airport New Area, Ruoergai Grassland, Tibet Mozhu Gongka, etc., and presided over the restoration of the "8.8" Jiuzhaigou earthquake-damaged Huohuahai Lakes, which was recognized by United Nations Educational, Scientific and Cultural Organization and the International Union for Conservation of Nature.

Prof. Pei presented his report from three aspects: ecological geological environment problems in western China, key technologies of ecological restoration in geologically and environmentally disturbed or damaged areas, and typical ecological restoration examples. In the report, he said that as there are difficulties of tight schedule, heavy task and high pressure for China in achieving carbon neutrality, we must continue to consolidate and improve carbon sink capabilities in order to achieve carbon peak and carbon neutrality. Geological disasters and major engineering projects have a great impact on geological environment, and ecological protection and restoration have made significant contributions to improving the capacity of terrestrial carbon sinks. Pei introduced the interdisciplinary application of materials science and ecological environment science with a variety of restoration cases, focusing on the application of glutinous rice mortar in the restoration of Huohuahai Lakes in Jiuzhaigou.

After the report, Prof. Pei discussed relevant issues with the teachers and students present, and took a group photo with the participating teachers.
