以2008年生态观测定位站调查数据和Landsat-5TM遥感影像为基础数据，建立森林水源涵养生态效益的常规多元统计模型得到回归模型的决定系数为0．788，平均检验精度81．1％。以模型估计的参数作为地理信息系统（GIS）的输入数据，估算2008年老山施业区物理量和价值量的空间分布特征，并核算出水源涵养生态效益物理量总量I=263．78万t，建立货币构造模型估算出水源涵养生态效益价值量总量E=131．89万元。分析物理量随地形变化的特征，其变化符合客观实际。

A conventional multivariate statistical model for estimating the ecological benefit of forest water conservation was con- structed by using the survey data from an Ecological Observatory Station and Landsat -5 TM remote sensing image data in 2008. The determination coefficient of the regression model was 0. 788 with average fitting accuracy of 81.1%. The parameters of this model were used as the input data in Geographic Information System （GIS） to reveal the spatial distribution of quantity and value in Laosban area in 2008, then the quantity of the total forest water conservation was computed as 2. 64 million tons. The total value of water conserva- tion derived from the currency structure model in the study area was estimated to be 1.32 million yuan. Finally, the variation features of the quantity changed with topographies were analyzed, which are in accordance with the actual situation.
