摘要
济南市南部山区是济南市的生态屏障,也是济南市泉群的水源补给区,但是长期以来人类的不合理开发利用,引起生态系统严重退化,表现为植被覆盖率降低、生物多样性降低、水土流失加重、景观破碎化提高等.生态系统退化严重限制了生态系统服务功能的正常发挥,妨碍了济南市的可持续发展.本文在分析济南市南部山区生态系统退化现状和原因的基础上,提出了生态系统恢复的合理对策.
Jinan southern mountain region is the ecosystem barrier of Jinan city,and is the recharge area of Jinan spring cluster as well.But due to irrational utilization for a long period,a series of ecosystem problems have come into being,such as reduction of vegetation coverage ratio,reduce of biological diversity,water and soil loss,landscape fragmentation and so on is presewted.The degradation has restricted the exertion of ecosystem services badly,and prevented the sustainable development of Jinan city.This paper puts forward reasonable countermeasures for restoring of degraded ecosystems in Jinan southern mountain region,based on analysis of actuality and reasons of degradation.
