扎龙湿地生态系统服务功能及恢复的研究

Study on Ecosystem Services and Restoration of Zhalong Wetland

扎龙湿地具有巨大的经济价值,其生态系统服务功能主要包括:调蓄洪水、净化水体、保护生物多样性、旅游服务、调节局地气候、补充地下水等。近50多年来,在人类活动和区域气候的相互作用下,扎龙湿地生态特征发生负面变化。具体表现如下:水资源严重不足;水环境恶劣、水体净化功能降低;生物多样性减少及生产能力的不可持续性;调蓄洪水能力降低等。为了阻止湿地的进一步退化,针对湿地的退化原因,提出了恢复湿地的具体措施。

<Abstrcat>Zhalong wetland has enormous economic value,and its main ecosystem services are as follows.Regulating and storing flood,purifying water body,protecting bio-diversity,tourist service,regulating the climate,and supplementing the groundwater,etc. In more than past 50 years,under the interaction of human activity and regional climate,ecological characteristics of Zhalong wetland produced the negative changes:water resource is seriously insufficient,water environment becomes abominable,and purifying function of water declines,bio-diversity is reduced,the production capacity is not sustainable,and regulating and storing the flood function is declined. In order to prevent the further degradation of the wetland,on the basis of the wetland degradation reasons,the concrete measures of wetland restoration are put forward.
