Location
Site location: Tianmu Moso bamboo flux site is located in Liyang city of Jiangsu province. (31°10′58ʺ N and 119°24′56ʺ E; elevation approximately 199 m). It belongs to the field plot of tate Key Laboratory of Lake Science and Environment, Nanjing Institute of Geography and Limnology, Chinese Academy of Sciences. The Moso bamboo forest in the upstream of Taihu region is also the typical vegetation type of the humid area of Southeast China.
Climatic
Climate condition: This site is in a subtropical humid monsoon climate. Multi-year mean annual temperature is 15.8 ℃ and mean annual precipitation is 1155.8 mm. Owing to the joint effects of plum rains and typhoon, rainfall during the period of March to September occupies 76% of the annual precipitation. Total annual solar radiation is 469.3 KJ/cm2. The yearly frost-free time add up to 224 days. The annual average sunshine time adds up to 2006.6 hours. It is also characterized by hot, usually humid summers and mild to cool winters. However, it is very suitable to the growth of vegetation.
Vegetation and soil
Vegetation and soil: Moso bamboo forest is the study vegetation type of tower-based measurements. Yellow sand soil is the main soil type, with the thickness of approximately 1 m. The content of organic matter is about 4.25%.
Observation system
Observation system: The flux tower was installed from the start of 2014 about 30 m high in the Moso bamboo forest. EC-150 was equipped at the height of 20 m. The conventional meteorological data comprise of wind direction/speed, air temperature/humility, and PAR quantum with five layers. Soil temperature, soil water content and electrical conductivity are measured at three layers. The sampling frequency is 10 HZ, and the average time of flux data is 30 min.
