| Abstract: | This study was carried out in the national reserve area, Lhalu wetland from 2001 to 2004. Routing statistics and sampling point method were used in this study to conduct a intensive survey about bird resources at the study site. The Lhalu wetland is located in the northwest of Lhasa, with the longitude range from 29° 39' 46.3" to 29°41'05.5"and the latitude range from 91°03' 48.5 "to 91° 06' 51.4 " and its present area is 6.2km2. Lhasa is the capital of the Tibet Autonomous Region and is located in the mid-south of Tibet. It is at the middle reaches of the Yalhong River and also on the riverbank in the valley of the Kyichu River which is one of the major tributaries of the Yalhong River. Numerous wetlands have been built on the Quaternary alluvial sediments and fluvial sediments along the Kyichu River. Lhalu wetland is a relatively well-preserved alpine natural wetland ecosystem and it plays an important role in maintaining the ecological balance, retaining the biodiversity, increasing the air humidity and influencing the climate of Lhasa City. It also provides important habitats for various animals. In this paper, birds of 13 orders, 24 families, 44 genera and 62 species are observed and recorded in the three years' fieldwork, including two bird species which are the national first-grade protected wildlife and 7 species that are the national second- grade protected wildlife. Also, two bird species are the second-grade protected wildlife in Tibetan Autonomous Region. There were 39 species of palearctic realm, 17 cosmopolitan species, 3 endemic species, and 3 species of oriental realm. In addition, 24 bird species are resident birds, 12 bird species are summer birds and 24 bird species are winter birds, and 2 bird species are passing bird. According to the present status of bird resources in Lhalu wetland, detailed countermeasures or approaches for the diversity conservation of bird habitat as well as water bird protection are suggested. |
