根据欧阳首承提出的“搅动能守恒定律”揭示的能量不能脱离物质，而必须给能量留有空间的理论，论述了能量空间与自然灾害和灾变动力的相互关系和作用，给出了能量空间在灾后重建工程、防洪减灾规划和生态环境规划等的应用和对策。并强调自然灾害、人为建筑工程“必须给能量留有空间”，才能更为有效地防灾、减灾。提出了“给能量留有空间”是针对当代科学遗漏了能量空间问题提出的新的科学命题。

Based on the theory of stir kinetic energy conversation law proposed by Ouyang Shoucheng, which revealed that energy can not break away from matter and space should be remained for energy, the relationships of energy space and natural disaster and catastrophic dynamics were discussed. The application and countermeasures of energy space in reconstruction after disaster, plan of flood control and disaster reduction, ecological environmental plan and etc. were proposed. It was emphasized that natural disasters and artificial construction project should remain space for energy for effective disaster reduction and prevention. It was suggested that "remaining space for energy"  is the new scientific proposition aim at the modern science's omission.
