【摘要】 以乌裕尔河滨河湿地退耕还湿示范区为研究对象,筛选供给、调节、文化和支持等四种服务功能及其相应评价指标,建立评价指标体系,分析了自然恢复模式下示范区退耕还湿前后的生态系统服务功能价值变化。结果表明,退耕还湿后,2015年乌裕尔河受损湿地生态系统功能最终修复价值为1.38亿元。该示范区退耕还湿后(14 026.5万元)生态系统服务功能价值远大于退耕还湿前(179.8万元)。可见,退耕还湿可以极大提高受损湿地的生态服务功能,对改善湿地生态环境具有极为重要的现实意义。更多还原

【Abstract】 Based on the demonstration model of returning farmland and wetland in Wuyuer Riverside Wetland,the four service functions(supply,regulation,culture &support)and their corresponding evaluation were selected,and the evaluation index system was established.The analysis system of natural restoration mode was analyzed.Changes in the value of ecosystem services before and after wet.Result shows that the final restoration value of the damaged wetland ecosystem in Wuyuer River in 2015 is 138 million Yuan after returning farmland to wetland.The value of ecosystem services in the demonstration area is much higher than that before returning farmland to wetland(1,798,000 Yuan).It can be seen that returning farmland to wetland can greatly improve the ecological service function of damaged wetland,which is of great significance to improve wetland ecological environment.更多还原
