| 摘 要： | 以3S技术为基础,对研究区内土地利用信息进行提取,并对凌河口湿地功能区进行划分,这是凌河口湿地生态环境需水计算的数据基础。根据凌河口湿地的具体情况,其生态环境需水量由湖泊-养殖塘生态需水、芦苇和水稻生态需水、湿地土壤生态需水组成。综合分析生态环境需水的现有计算方法,结合凌河口湿地各生态系统类型的特点,建立适合于研究区的生态环境需水计算方法。计算结果表明:适宜生态环境需水量为28 666×104 m3/a;多年平均降雨下的最小生态环境需水量为7 174×104m3/a,并给出了不同降雨频率下的最小生态环境需水量。为便于水资源配置,给出了适宜与最小生态环境逐月用水过程。

| Abstract: | In this study,based on 3S technology,the information on land usage at Linghekou wetlands was collected and the wetlands were divided based on their functions.This formed the basis for calculating the eco-environment water requirement at Linghekou wetlands.According to the specific circumstances at Linghekou wetlands,the eco-environment water requirement includes the lake-breeding pool ecological water requirement,reed-rice ecological water requirement,and wetland-soil ecological water requirement.With a com... |
