Abstract: Based on the summing up of the concepts of"ecological effect"at home and abroad,this paper pointed out that in researching ecological effects,both the extrinsic process and the intrinsic mechanism should be regarded.The extrinsic process includes the changes of the structure and function of ecosystems caused by anthropogenic disturbance,while the intrinsic mechanism contains the relationships of ecological disturbance with its driving forces,and with the dynamics of ecological changes(environmental pollution and ecological deconstruction).The negative ecological effects caused by environmental pollution(water,soil and air pollutions)and ecological deconstruction(road building,hydroelectricity dam construction,and land use/cover change)were reviewed,and the present problems and further research topics(comprehensive research of extrinsic process and intrinsic mechanism,systematic multi-scale research,etc.)were put forward in light of available information.
