Huge mountains extend from the forest with trees covered resembling a sea of forest. The are deflated hills around the Kanbula Forest that are formed due to erosion from wind and sand. The hills are called red cloud landforms (China Ecotourism 2009).
Amid the mountains, the weather of the forest change frequently. The forest does not experience four distinct weathers, but the hot and cold weathers that it experience are divided into two quarters. Cold seasons at the forest features cold, windy and dry air. Warm season features monsoon and warm and humid air. The forest’s tough topographical features form a role of microclimate. According to meteorological data records, the average temperature of the forest is l-2.9. The warmest month (July) has a daily temperature of 11.5-13.4. The coldest month (January) has average daily temperature -12-10.1. 3-9 month average is temperature of 7-8.4 ℃; stable over time through 0 ℃ for 190 days; plant growing period mean diurnal temperature 13.l ℃, frost-free period is about 120 1 134 days; ≥ 0 ℃, ≥ 5 ℃, ≥ l0 ℃ accumulated temperature were A 1500 ℃ 1800 ℃, 1300 ℃ for a 1700 ℃, 900 ℃ for a 1100 ℃. 2622-2900 hours of annual sunshine hours, global solar radiation 609-647 kJ / cm. Annual rainfall is 450-490 mm, annual evaporation 1923 mm. Annual average wind speed 19 meters / second, more concentrated in the January-April.
Kanbula forest’s soil has five categories. First type is alpine shrub meadow soil that is found at the altitude between 3600 and 3900 meters. Second is the upland meadow shrub soil that is found at an altitude between 3200 and 3700 meters. Third is the grey cinnamon soil that is found at 2600 and 3400 elevation. Fourth type is the chestnut soil that is found at an altitude of 2600 and 2800 meters. Fifth is the grey desert soil that is found at an elevation below 2400 meters (Qinghai Forest Survey Records).
