Historical evolution

In 1995, the government of the Tibet Autonomous Region started the protection project in an all-round way.

In 1997, we completed the collection and investigation of wetland status, social, cultural and geographical data.

On May 25, 1999, the government of the Tibet Autonomous Region officially approved the establishment of the Lalu wetland as a nature reserve of the Tibet Autonomous Region.

In 2000, Lhasa municipal government issued the "Lhasa Lalu Wetland Nature Reserve Management Measures", and prepared the "overall planning of Lhasa Lalu Wetland Nature Reserve", and established the management station of Lhasa Lalu Wetland Nature Reserve.

In December 2004, Lalu wetland autonomous regional nature reserve was promoted to National Nature Reserve and passed the evaluation of national expert evaluation committee.

On July 23, 2005, the State Council approved the new Lalu Wetland Nature Reserve as a national nature reserve.

Development and utilization

scientific research

From 2001 to 2004, the bird resources of Lalu Wetland National Nature Reserve were investigated in detail by route statistics and sample point statistics. According to the current situation of bird resources in Lalu wetland, the paper puts forward some specific countermeasures for the protection of bird habitat diversity and waterbirds in Lalu wetland.

From 2001 to 2003, the vertebrate diversity of Lhalu Wetland National Nature Reserve in Lhasa, Tibet was investigated.

From July 2009 to August 2012, five sample plots were set up in Lalu Wetland National Nature Reserve. Water samples and soil samples were collected in summer and autumn respectively. The protozoan species diversity and community structure characteristics of Lalu wetland were studied by living culture and fixed staining.
