卧龙湖湿地天然恢复的可行性分析

【摘要】 讨论了卧龙湖近期干涸的原因以及天然恢复的有利和不利因素。提出:气候趋于干旱化,流域连年降水减少,人为截流、分割统一的湿地生态系统是近期卧龙湖干涸的主要原因。从长期发展趋势看,周围气候正朝着干暖方向发展,科尔沁沙地扩张,人类干扰逐渐增强,导致卧龙湖湿地难以天然恢复;从短期发展趋势看,气候变化有很大的波动性,从2005年开始,卧龙湖所在地区进入丰水年,同时人类干预也有积极的一面,因此卧龙湖湿地的水量可以短期恢复,整个生态系统也能够在一定程度上得到恢复。更多还原

【Abstract】 The paper mainly discusses the reasons of drying up of Wolonghu lake in recent years and analyses the advantages and disadvantages of the natural recovery for the lake wetland.The main causes of the lake’s drying up are discussed,including:climate is changing to aridity,the annual precipitation of the drainage area has been reduced in successive years,the water of the lake has been intercept by people,and the whole wetland ecosystem has been split.For the long trend,the climate ambient is trending to drier and warmer,Korqin sands is expanding,and the destroy of humankind is boosting up gradually,so Wolonghu wetland has difficulty to come back naturally,it ultimately develops into wither away.For the short trend,the climate change has great fluctuation,the area of Wolonghu Lake has turned into abundant precipitation years since 2005,and human intervention also has positive function,so the water quantity of Wolonghu wetland may be recovered in a short time,the whole ecosystem can be restored in some way.更多还原
