Recently, the research team led by Prof. Wang Kelin from the Institute of Subtropical Agriculture, Chinese Academy of Sciences pioneeringly analyze the surface process and the causes of human disturbance in the watershed in the historical period based on the filling process in karst depression and the historical environmental information of sediment. An important progress was made in the impact of human disturbance on soil erosion in the karst region of southwest China during the historical period.
In the previous studies, Prof. Chen Hongsong from the Institute of Subtropical Agriculture of Chinese Academy of Sciences, led the team to found that some plants in the soil-dominated habitat (called soil plants) usually preferred to absorb the shallow layer water, while in the rock-dominated habitat others (called rock plants) could rely on deep layer water to alleviate water stress. “Now, we try to quantified the effects of soil and epikarst water on transpiration based on the physiological characteristics of root and leaf in karst region in southwest China.” Prof. Chen said.
Large-scale ecological projects have significantly “greened” the karst region in Southwest China over the past 20 years. However, the fragile geological setting, the frequent occurrence of extreme droughts in recent years, in the context of global climate change, has increased uncertainty and risk in the recovery and growth of vegetation.
A Researcher team led by Dr. Xu Xianli, from the Institute of Subtropical Agriculture, Chinese Academy of Sciences, have made significant progress in understanding how agricultural ecosystems in the karst depressions of Southwest China respond to flood risks.
Recently, researchers led by Prof. Kelin WANG from the Institute of Subtropical Agriculture, Chinese Academy of Sciences, demonstrated that the spatial variation and controlling factors of runoff and sediment yield (SY) in different karst watersheds were quantitatively analyzed.
Researchers from the Institute of Subtropical Agriculture, Chinese Academy of Sciences, in partnership with international colleagues, made strides in reveal soil organic carbon sequestration mechanisms in Eastern China.
ssociate Prof. Yan Qiongxian and Prof.Tan Zhiliang visited Suranaree University of Technology (SUT), located in Nakhon Ratchasima Province, Thailand, and held in-depth discussions with international cooperation partner Dr. Pramote Paengkoum's research team during August 20 to 22.
