Station Description:

General Description:

Yingke observation station, located in the middle reaches of Heihe river basin, was installed in the farmland of yingke irrigation district in Zhangye, Gansu province. The perimeter of experiment field is very flat and open, the spacing of windbreak forest is 500m from east to west, and from south to north it is 300m. So, Yingke observation station is an ideal site for oasis cropland, which is 20m long from east to west and 15m wide from south to north. In the east of experiment field, there existed an observation tower about 10m high for microclimate, but an eddy covariance measurement system is installed in the west.
