Eco-environmental Demand for Water in Wetlands at Liaohe Estuary
摘要
Abstract
Determining the optimum and minimum eco-environmental demands for water in the wetland at Liao-he estuary is important to sustain ecosystem health and productivity. This paper established a wetland model by dividing eco-environmental demand for water into consumable and non-consumable water. The data needed in the model was obtained from satellite imagery using the 3S technology. We then applied the model to calculate the eco-environmental water requirement, sustainable eco-environmental water requirement, as well as mini-mum eco-environmental water requirement under different precipitations in 2000, 2005 and 2014 respectively. The results showed that the optimal eco-environment requirement was 99554.92 × 104 m3. For 100%, 75% and 95%of the average annual rainfall, the minimum eco-environmental water requirements were 20220.13×104 m3, 22362.31×104 m3 and 24314.98×104 m3 respectively.关键词
