| Zusammenfassung |
| Water plays a significant role in
wetlands. Floodwater utilisation in wetlands brings a wide range of wetland
services, from goods production and water regulation to animal protection
and aesthetics related to water supply in wetlands. In this study, the
floodwater utilisation values of wetland services were estimated within the
Momoge wetland and Xianghai wetland in western Jilin province of
northeastern China. From 2003 to 2008, the floodwater diverted from the
Nenjiang and Tao'er River is 381 million m3, which translates into a
monetary value of approximately 1.35 billion RMB in 2008 (RMB: Chinese
Currency, RMB 6.80 = US$ 1), and the ratio of economic value,
eco-environmental value, and social value is 1:12:2. Besides the monetary
value of the water itself, excessive floodwater utilisation may bring losses
to wetlands; the threshold floodwater utilisation volumes in wetlands are
discussed. Floodwater utilisation can alleviate water shortages in wetlands,
and the evaluation of floodwater utilisation in wetland services in monetary
terms is a guide for the effective use of the floodwater resources and for
the conservation of wetlands. |
