I learnt that phonon is quantum something of vibration. But I cannot understand what 'phonon concentration' and 'phonon scattering' mean, and how they relate to the temperature or carrier mobility. Does it have a intuitive picture?

You can consider (acoustic-)phonons as particles of sound waves. Sound waves travel through crystals, they can scatter, their propagation speed depends on temperature (volume expands), carrier mobility, ... – Timeless Nov 16 '15 at 17:17
