森林水源涵养是森林生态功能的重要指标，测定森林的水源涵养量能很直观地了解森林资源的生态价值，能够为确定森林资源保护措施与经营策略提供有力的数据支持。以吉林省柳河县为研究区，以Landsat-5 TM遥感影像为基础数据，提取相关因子，根据样地实测数据建立森林水源涵养遥感估测模型，经过精度检验，模型的预测精度达到79.24%。利用模型进行了柳河县森林水源涵养量反演，得出柳河县森林水源涵养量为4.62×106 m3。形成柳河县森林水源涵养量分布图，并从空间上分析了森林水源涵养能力与空间要素的关系。
Abstract
Forest water conservation is an important indicator of the state of the forest ecological function, the estimation of the volume can be a very effective way of understanding the ecological value of forest resources, and the data support for the determination of management strategy for the forest resources. The author chose Liuhe County in Jilin Province as the study area, and extracted relevant factors to establish the model of remote sensing estimation of forest water conservation volume in Liuhe County based on Landsat-5 TM remote sensing image data. It showed that: the prediction accuracy of the model was 79.24%, after precision test. From the distribution map of the forest growing stock of Liuhe, as a result of the inversion of the model, it showed that the forest stock volume was 4.62×106 m3. The distribution of forest water conservation quantity Liuhe Country was formed for analysis of the relationship between ability of water conservation forest in space and spatial elements.
