Abstract: 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.
