Qinghai News Network · Damei Qinghai Client News On July 29th, the reporter learned from the Qinghai Provincial Administration of Qilian Mountain National Park that the three -year -old Qilianshan National Park Qinghai District Typical river and wetland water ecological environment and aquatic biological diversity special survey The evaluation work was successfully completed.

"Said Han Qiang, deputy director of the Qinghai Provincial Administration of Qilian Mountain National Park.

Since 2020, the Qinghai Provincial Administration of Qilian Mountain National Park and the Institute of Aquatic Biological Research of the Chinese Academy of Sciences have jointly launched a special survey and evaluation of the typical river and wetland aquatic ecological environment and aquatic biological diversity of the Qilianshan National Park. After 3 years, four field surveys were completed, covering different stages of rivers and wetland thawing periods. It obtained more than 6,000 water environment data and nearly 10,000 aquatic biological data. The survey scope includes all rivers and wetlands in Qilian Mountain National Park. A total of more than 50 sampling points are set up. Through the survey indicators, water -based algae, plankka, benthic animals, fish and aquatic plants such as rivers and wetlands are accurately evaluated the ecological environment of the water, and more than 600 aquatic biological specimens have been produced.

The survey results show that the quality of rivers and wetland in the Qinghai area and surrounding areas of Qilianshan National Park and the surrounding areas maintain the stable quality of the water environment of the groundwater environmental quality standard II level.

Comprehensive 'physical examination'. Accurately evaluated the water ecological health status of the source area of ​​the northwest, and provided scientific data for the protection management of Qilian Mountain National Park.
