三江平原湿地生态服务功能重要性

Ecological service function significance of Sanjiang plain wetland

湿地是地球上具有多种独特功能的生态系统,它不仅为人类提供大量食物,原料和水资源,而且在调节气候、调蓄水量、净化水体、保持水土、物质生产、保护生物多样性和提供动植物栖息地、教育休闲旅游等方面也具有重要的功能。三江平原作为我国最大的淡水沼泽湿地集中分布区,经过几十年的开垦,已成为我国重要的商品粮产地。尽管近些年对三江平原湿地进行了大面积的排水开垦,但三江平原湿地仍具有十分重要的蓄水、调洪功能与生物多样性价值,同时三江平原湿地对调节当地的气候也有着重要的作用。由于目前湿地生态系统破坏较为严重,生态服务功能日趋降低,所以保护湿地,恢复湿地,进行湿地生态功能的调控是一项刻不容缓的工作。

Wetland is an ecological system that it has a variety of unique features,it not only provides plenty of food for human beings,raw material and water resource,but also has important function in climate regulation,water regulation,water purification,soil and water conservation,material production,protection of biodiversity and provide habitat for animals and plants,education,leisure and tourism.Sanjiang plain as China＇s largest concentrated distribution area of the freshwater marsh wetland,after decades of development,already became our country＇s important commodity grain production.Although in recent years there were large drainage reclamation of wetland in Sanjiang plain,it is still important to water,flood regulation functions and biodiversity value,at the same time the Sanjiang Plain Wetlands also plays an important role in the regulation of the local climate.Due to the more serious destruction of wetland ecological system,ecological service function is reduced,so the wetland protection,wetland restoration,wetland ecological function regulation is a brook no delay work.
