his paper, aiming at Chinas strategic adjustment of energy structure and a healthy biomass industry, uses related data and past research to reveal the main issues,and to analyze the constraints, and to clarify the future key missions. The main issues include high cost,lack of core technologies and overall planning, rough supportive policy, which, if resolved,will be constrained of biomass energy supply, current energy system and environmental protection. This paper present suggestions on clarifying the situation,overall planning, optimizing standards,technical innovation,improving services,cultivating markets and exploring Chinese featured industrial developing path and modes.

The changes in land occupancy forms bear the characteristics of times. The imperialist invaders broke the normal development of old China’s self-demand-self-supply economy. During land privatizing, the land ownership had been concentrated on the hands of old landlords, new bureaucracy, business men, usurers and imperialist invaders, resulting in a worsening living condition to China’s peasants. This paper, based on the changes in land occupancy forms and landlord class, insists on a necessity of “collective ownership of land” during land moving and contracting.
