Study on the Structure and Functions of Water ConservationForest at the Watershed Level in Mountainous Area of Beijing

Abstract

Abstract: This paper explores the relationship between structure and function of water conservation forest at the watershed level from the basin forest age structure,ratio of the area and spatial pattern.It establishes coupling model between structure and function at the watershed level.Finally,the model is used for evaluating the water conservation forest of Beijing mountainous area.The results show that,middle-aged and young forests are primary in the water conservation forest of Beijing mountainous area,and the area ratio is 30% of water conservation forest.The space configuration of the forest patches are uniform,and the function of forest will grow gradually along with the increase of age.

Key words: mountainous area of Beijing, water conservation forest, watershed, structure, function
