Bio-ecological resources of saline lakes in Tibet and their economic prospect

In the paper, the concept of "saline Lake" and its studies are reviewed, focusing on the historical survey data of biological and ecological resources of Tibet Saline Lakes. Based on the survey data obtained by our research team during the last 20 years, the 209 lakes in the northern Tibet are classified into various salinity groups and various area groups. Based on both the northern Tibet ecological characteristics and the ecological demand for the regional economic development, the lake resource potential is analyzed with respect to the Artemia ecological restoration in Tibet saline lakes, as well as the advantages and the significance of developing the saline lake agriculture. Some principles of ecological protection and development of biological resources in the Saline Lake system are proposed.The species resources and the distribution characteristics of phytoplankton and zooplankton and macrophytes are discussed, focusing on the biological resources and their scientific values, including the diatom, the Artemia, the salt alga (Dunaliella sp.), the water agaric (Nostoc sp.), the stonewort(Charophyta) and the pondweed (Potamogeton sp.).From the successful experiences of the ecological restoration in the Tibet Dangqong Co saline lake, the significance and the economic importance of the saline lake ecological restoration are clearly seen. The resource situation and the prospect of development and utilization of Daphniopsis tibetana Sars and Dunaliella sp. in Tibet are discussed, and the cold-water fish aquaculture as the competitive industry is proposed; the sci-technological base and the government effective management are considered as the fundamental guarantee to develop the bioindustry of salt lakes in Tibet.
