| Abstract: | Based on the introduction to urban forest resources in Nanjing and the guidance of scientific,dynamic and operational principles,this paper puts forward the composite index system of regional forest ecological service quality evaluation.First,the reliable basic data quantifying the index factors is derived from the remote sensing images in 2000 and 2007 based on 3S technology.Then it plans for an analysis of the main factors and confirms the relative importance and structure through applying the Analytic Hierarchy Process(AHP).The weighted method evaluates the rate of Nanjing urban forest.The result indicates that the construction for forest ecology has succeeded in Nanjing in recent years. |
