Abstract
In this paper,Liaohe Delta was taken as the study target.Correction factors of the ecological service value equivalent table was used in combination with the ecosystem service value assessment to analyze the spatial-temporal dynamic variation characteristics of land use patterns in three periods as well as the service value changes.The results showed that the land use structure was mainly composed by paddy field (56.76％),followed by wetland (15.29％) and construction land (14.77％),accounting for 86.82％ of the total area.Land use pattern changed quickly from 1986 to 2000 but slowly from 2000 to 2010.A common feature during these two periods was that the area of construction land increased steadily,but that of wetland decreased gradually.The total value of land use ecological service reduced year by year.Wetland service value contributed the most to the total service value,accounting for over 60％.关键词
