济南市南部山区山脊生态廊道研究

[目的]对济南市南部山区山脊生态廊道建设进行研究。[方法]在分析济南市南部山区自然概况以及存在问题的基础上,通过对2004年研究区土地利用类型图与地形图的叠加分析,研究不同坡度和坡向对山脊生态廊道建设的影响,并有针对性地提出了具体的建设方案。[结果]耕地、林地、草地以及裸岩石砾地均以0～5°坡度为主,其面积比例分别为83.2%、72.43%、85.05%和96.13%;耕地、林地、草地主要分布在阴坡,其面积比例分别为29.20%、31.00%、34.61%,这与阴坡水分条件较好有关。由于研究区不同坡度和坡向下土地利用类型不同,在山脊生态廊道建设时应因地制宜,依据不同的坡度和坡向提出合理的廊道建设方案。[结论]该研究为济南市南部山区的生物多样性保护提供了依据。

Research on the Ridge Ecological Corridors in the Southern Mountain Region of Jinan City

[Objective] The aim is to study the construction of ridge ecological corridors in southern mountain region of Jinan City.[Method] The general natural situation and existing problems of southern mountain region of Jinan City were analyzed firstly,then the effects of slope and slope direction on the construction of ridge ecological corridors were studied through the overlapping analysis of land use type map and topographic map,and the corresponding construction schemes were put forward.[Result] The main slope...
