摘要
以洪河国家级自然保护区湿地为例 ,对其各生态环境需水的配制要素—植物需水量、土壤需水量和野生动物栖息地需水量分别进行了计算 ,最后估算出了该湿地植被生长期内生态环境需水量。计算表明 ,洪河国家级自然保护区湿地最小生态环境需水量为 1 .0 2亿m3,优等生态环境需水量为 1 .95亿m3。最后 ,针对保护区湿地目前面临的水文危机 ,提出了相应的措施和对策。
The definition and contents of eco-environmental water consumption for wetlands were discussed. The eco-environmental water consumption for Honghe National Nature Reserve wetlands were analyzed, and three main components including water consumption of vegetation, soil, and wildlife habitat were calculated respectively. Results showed that the minimum eco-environmental water consumption for Honghe National Nature Reserve wetlands was 1.02×108m3, and the optimum water consumption was 1.95×108m3. It was a formidable task to meet this water demand. To mitigate the hydrologic pressure on Honghe National Nature Reserve wetlands, corresponding countermeasures were suggested.
