The answer is: They cut down trees for heating & building
Until today, the chinese government hasn't developed a sustainable plan to address the issue that arise from over exploitation of the environment.
Because of this, people and corporations in china often conduct unsafe measures when they cut down trees. They do not have to pay attention to the regeneration of the forest. Because of this, forestland has declined in eastern China.

The piece of spectral data necessary to determine the spectral class of a star is Temprature.
Spectral records are. Data measured for precise wavelengths of radiation associated with the phenomenon being found. The statistics can be a non-stop feature of wavelength fee or can also imply the most effective values at discrete wavelengths.
Spectral data is the procedure of estimating the power spectrum (ps) of a sign from its time-domain illustration. Spectral density characterizes the frequency content material of a sign or a stochastic manner.
Spectral data allows remodeling a time collection (time signal) into its coordinates in the area of frequencies, after which to investigate its traits in this area. The magnitude and phase can be extracted from the coordinates.
