人为干扰对滨海红树林湿地的影响

红树林是热带和亚热带的重要滨海湿地类型,在维护海岸生态平衡方面有独特的作用。国内外学者对人为干扰红树林湿地进行了广泛研究,这些人为干扰可分为6个类型,包括具有显性影响的土地利用转化、城市化及工业化、木材及薪材过度利用和具有隐性影响的污染物排放、林内挖捕、林内禽畜放养。具有显性影响的干扰类型较容易得到重视与研究,具有隐性影响的干扰类型往往被忽视,而这些隐性影响也严重地危害红树林湿地的健康。针对这些人为干扰,提出了保护滨海红树林湿地的有效管理措施。

Impacts of Human Disturbance on Coastal Mangrove Wetlands

Mangrove forest is an important type of wetland in tropical and sub-tropical zone,which has special function in maintaining ecological balance in the coastal regions.Scholars both in China and foreign countries have widely studied the impacts of human disturbance on mangrove wetlands. Human disturbance is divided into six types,including obvious impacts such as mangrove land-use conversion,urbanization and industrialization, over use of timber and fuel-wood and subtle impacts like discharge of pollutants,fishing activities and livestock-raising in the mangroves.Usually the evident impacts are given attention and well studied,while the subtle impacts are easy to be neglected.In fact,the subtle impacts are also imposing serious threat to the health of mangrove wetlands.Some effective management measures were proposed for protecting coastal mangrove wetlands.
