In order to determine the degree of anthropogenic disturbance potentiality (ADP) of the area a rapid ecoassessment technique was developed on the basis of actual vegetation map. ADP degree of relevant unit cell was computed by using four criteria of land use patterns such as forested area, open water and stream, agricultural area, and urbanized area. Ultimate ADP degree of each cell was obtained by means of direct and indirect computation process. Finally the map of ADP was drawn and analyzed. Vulnerable cell and disturbance nuclei were determined according to disturbance vector which is a kind of potential disturbance pressure of relevant cell influenced by surrounding cell. A case study was accomplished in the Gijang area of Pusan metropolitan city. 973 meshes (500m×500m) were analyzed and a total of 79 meshes were currently threatened. Present technique of rapid ecoassessment was practically useful for diagnosing and planning land use.
