STORY: China's Yangtze River undergoes "physical examination" DATELINE: May 18, 2023 LENGTH: 00:01:25 LOCATION: WUHAN, China CATEGORY: ENVIRONMENT SHOTLIST: 1. various of staff members carring out examinations along the Yangtze River 2. SOUNDBITE (Chinese): ZHANG JING, Head of pilot project of Yangtze River water ecological assessment and monitoring STORYLINE: The Yangtze River, the longest waterway in China, has undergone "physical examinations." Since April this year, China has launched an assessment of the water ecology in the Yangtze River Basin. Researchers from multiple departments will carry out "physical examinations" for 331 point positions, which are set in the Yangtze River's mainstream and tributaries, main lakes and water reservoirs. These point positions are distributed from northwest China's Qinghai Province to Shanghai, and the examinations will last until June this year. One of the important tasks of the examinations is to collect samples of large benthic invertebrates and zooplankton,

Scientists investigate micro ecosystem in Yangtze headwaters

STORY: Scientists investigate micro ecosystem in Yangtze headwaters DATELINE: Aug. 3, 2022 LENGTH: 00:01:13 LOCATION: XINING, China CATEGORY: SCIENCE SHOTLIST: 1. various of Chinese scientists investigating micro ecosystem in Yangtze headwaters STORYLINE: Chinese scientists launched an expedition on Sunday in the headwater regions of the Yangtze and Lancang rivers in northwest China's Qinghai Province, to investigate the regions' water resources and ecological environment. The headwaters of the Yangtze River, located on the Qinghai-Tibet Plateau, are rich in microscopic organisms such as phytoplankton, zooplankton and benthic animals. 　　 These biological communities which need to be observed under a microscope contain various species of different shapes. They provide energy for the aquatic ecosystem including food for fish. 　　 They are an indicator for the ecological health status of the Yangtze headwaters, and can reflect water quality. 　　 Data from the expedition shows that now there are more than 40 sp

Chinese scientists launched an expedition on Sunday in the headwater regions of the Yangtze and Lancang rivers in northwest China's Qinghai Province, to investigate the regions' water resources and ecological environment. The expedition will conduct scientific investigations into the water resources, river hydrology, water ecology, glaciers, soil erosion and permafrost of the regions, among other things, according to the Changjiang River Scientific Research Institute (CRSRI) of the Changjiang Water Resources Commission, which is leading the expedition.
