摘要
摘要: 对白洋淀在特别枯水年情况下,设计按最小生态水位补水、按适宜生态水位补水和不补水3种方案。对补水后湿地各类生态服务功能相比不补水(即只使用白洋淀湿地生态水权提供入淀径流)产生的变化进行计算,并运用市场价值法、类比法和影子工程法等方法,对各类服务功能变化的经济价值进行评估,得出白洋淀湿地补水的生态效益价值。结果表明:白洋淀湿地按最小和适宜生态水位补水,补水量分别为12610×104和26 819×104 m3,补水的生态效益价值分别为57 036×104和135 646×104元,其中间接使用价值分别为52 255×104和124 244×104元,分别是直接使用价值的10.93倍和10.90倍;按最小和适宜生态水位补水,单位补水量的生态效益分别为4.5和5.1元•m-3,2种方案补水的生态效益都很显著。
Abstract: Based on the situation of the Baiyangdian Wetland in the extremely dry year three water supplement schemes, i.e. minmimal water level scheme, appropriate ecological water level scheme and no water supplement scheme, were designed to explore and calculate variations of various ecological service functions of the wetland as affected by water supplement , and economic values of the variations were assessed using the market value method, analogue method and shadow project method, and hence values of the ecological benefits of water supplement were worked out. Results show that according to the minimal water level scheme and the appropriate water level scheme, 12610×104 and 26819×104 m3 of water should be supplemented, respectively, and 57036×104 and 135646×104 Yuan (RMB) of ecological benefits would be created, respectively, in anticipation, including the indirect use value of 52255×104 and 124244×104 Yuan, respectively, which is 10.93 times and 10.90 times of the direct use value, respectively.The ecological benefit per unit water supplemented to the Baiyangdian wetland of the two schemes is 4.5 and 5.1 Yuan•m-3,respectively. It is quite obvious that the ecological benefits of the two schemes for water supplement to the Baiyangdian wetland are both very significant.
