文摘内容 During land transformation process in the human history,naturalized plants were introduced to several land use patterns by the different ways of plant itself .Including some naturalized plants that had been contribute to land restoration,many naturalized plants have been invaded to original habitat or landscape for native plants.Once the plants were colonized,they extend their area and population size.Urban developed areas often give an impotant role of source habitat for naturalized plants and expanding their popuation size.In recent,this tituation is appearing as one of environmental problems about the urban landscape management controlling the naturalized plants that invaded in the developed area and conserving the native vegetation.This paper is focusing on relationships between distribution of habitat of naturalized plants and landscape patch in urban area in Seoul.Gengdong-Gu ,one of the administrative areas in Seoul was selected for this study.We examined the recent land use change using LANDSAT TM data and spreading of the representative naturalized plants(Robinia pseudoacacia and Eupatorium rugosum)by Seoul Biotope Mapping Project and field survey in 1999.As a result,these two species were often occurred in the same habitat and distributed in forest edge disturbed by man.Their distribution patterns were related to landscape indices (patch size and shape)in the forest edge。
