| 摘 要： | 在对北京市密云水库密云县境内集水区的土壤、地形、植被类型等因子实地调查的基础上,分析了该区域的立地条件的异质性。根据立地分类主导因子原则和科学实用原则,确定了海拔、坡向、土层厚度等为主导因子;将密云水源涵养林立地类型划分为3个立地类型小区,9个立地类型组,15个立地类型。同时,结合地理信息系统技术对密云立地分类进行了研究,对最大蓄积量进行了估算,并编制了密云水源涵养林区立地类型图,为密云水源涵养林的林种配置和经营方式提供了科学的依据。

| Abstract: | Through the investigation of soil,topography,and vegetation in the forest lands of Miyun County,different site types are analyzed.According to the principle of key factors and the principle of practicality,evaluation,slope orientation,soil thickness and so on are selected as the key factors.Site types in the county are classified into 3 small site-type districts,9 site-type groups,and 15 site types and then the potential of accumulation is calculated.Moreover,the map of the site type classification is made by using GIS.It can provide a scientific reference for the allocation and plant management pattern of water conservation forests in Miyun County. |
