摘　　要：生态力指生物与环境之间物流、能流和信息流的驱动力。生态内力是生物的生理代谢活动能力，它把从环境中吸入的物、能转化为生物本体的物、能，并将部分内在的物、能输出体外，显示了生物本身的活力和生产力；生态外力则是环境综合作用向生物输送物、能的力量。生态内力与生态外力之和称为生态合力，它是生态动态平衡的指标，表示环境条件的适宜程度。生态力的研究尚属起步，其概念、理论和方法有待进一步发展和完善。Ecological foreces (or ecoforces) refer to the driving mechaninsms of material exchange, energy flow and information transmission between organisms and their surrounding environments. The internal ecological forces ale the physiological dynamics of organisms used to convert the materialenergy absorbed from the environments into the components of their wiles and at the same time to release a part of their inner material-emergy into the surroundings that indicate the vigor and productivity of organisms. While the external ecological forces derived from the integration of environmental factors function to supply the material-energy to the orgsnisms. The internal and external ecological forces interact simultsneously to form resultant ecological forces which could serve as an indicator of ecological dynamic equilibrium. Research on ecological forces is still in an initial stage: Yet their conception, theory and method need further to be developed.
