北京密云水库集水区森林景观生态分类研究

以遥感影像和地形图件为基础,结合二类调查资料和GPS实地布点,借助于ARC View和Fragstats软件,从不同尺度将集水区森林景观进行了分类归并,包括2个森林景观类、3个森林景观系、6个森林景观组、5个森林景观型和9个森林景观亚型。其中,生态型森林景观系是研究区域内的森林景观主体,森林景观多为幼龄林和疏林,针阔混交林的比重相对较低。各种森林景观类型景观斑块面积较破碎、形状较规则,受人类活动干扰普遍较为严重,宜以培育水源涵养与水土保持功能为主要目标,加强森林抚育,发展多种模式的混交造林。

Ecological Classification of Forest Landscape in Beijing Miyun Reservoir Water Catchment

The forest landscape in Beijing Miyun reservoir water catchment is ecologically classified based on remote sensing images and digital topographical maps and by using ARC View and Fragstats.Some data from forest field survey and GPS locations are also used in this work.The forest landscape in this research area can be divided into two forest landscape kinds or three landscape series or six landscape groups or five landscape types or nine landscape sub-types.The ecological type forest landscape is the dominant one in this area.Most of the forest landscape is covered with young forest and open forest.The proportion of mixed forest is relatively low.The area of each landscape patch is mostly fragmental with regular shape,which means a heavy human disturbance occurred in the forest landscape.Therefore,the forest management should aim at water resource reserving and soil and water conservation.And some work as to forest tending and diverified practices of planting mixed forest should be strengthened.
