description |
The two large lakes in the center of Mongolia, located between the Khangay mountain ranges and branch ranges, are the sites of environmental changes affected by recent climate change. There is scarce research in Mongolia that examines and evaluates how climate change affects major tourism destinations that are part of the forest-steppe region with an abundance of climate resources. In this study, Trend analysis, Statistical analysis methods, and Water Normalized index (NDWI) were used. The results indicated that, in the area of Ulaagchiny Khar Lake, Terkhiin Tsagaan Lake, evaporation increased when the Mann-Kendall value of the average air temperature trend increased by Z=2.61 and Z=0.90, respectively. Precipitation decreased Z=-0.65 or sharply in the vicinity of Ulaagchiny Khar Lake, and the average air temperature increased, resulting in a sharp decrease in the volume of the lake y=-0.0067x+0.5307 R²=0.6957. But bytime's periodicity, the water's volume increased from 1993-1999 before abruptly declining after that. However, precipitation Z=2.72 trend increased near Terkhiin Tsagaan Lake, while the lake's volume slightly decreased y=-0.0003x+0.3702 R²=0.0341, which is associated with an increase in air temperature.
