Abstract Methods
for calculating the eco-environmental water demand in the Zhalong Wetland are
presented. The eco-environmental water demand for the main types of land use
including the lakes and reservoirs, the shallow water areas and the reed
marshes in the Zhalong wetland are calculated and the total appropriate and
minimum water demand quantities assessed. Results show that the
eco-environmental water demand for the whole Zhalong Wetland varied between 522
× 106 m3 and 592 × 106 m3 during
the period from 1986 to 2002. The appropriate quantity for the
eco-environmental water demand is calculated as 555 × 106 m3;
the minimum eco-environmental water demand, with an assurance probability of
75% or 95%, is 288 or 354 × 106 m3, respectively.
