摘要
在结合南安市山美水库库周水源涵养林地形、土壤和植被类型实地调查的基础上,利用遥感影像图、二类森林资源调查数据及地形图,分析该区域立地条件的异质性。根据立地分类主导因子原则和科学实用原则,选取海拔、坡向、坡度等为主导因子,将山美水库山美工区水源涵养林立地类型划分为2个立地类型小区,4个立地类型组,8个立地类型。同时利用GIS编制山美工区水源涵养林立地类型图,为构建树种配置合理的异龄复层混交水涵林提供参考。
Through the investigation of topography,soil and vegetation in the forest lands of Shanmei Reservoir,Nan'an city,different site types were analyzed.According to the principle of key factors and the principle of practicality,evaluation,slope orientation and slope gradient were selected as the key factors.Site types in the county were classified into two small site-type districts,four site-type groups,and eight site types and then the map of the site type classification was made by using GIS.It can provide a scientific reference for constructing unequal age multi-layer mixed water conservation forest that reasonable allocation of tree species.
