摘要
从系统生态学的角度出发,将湿地生态系统储水划分为物理储水和生物储水两部分,物理储水主要指地下水和地表水,生物储水包括湿地生态系统内植物体和动物体储水。由于湿地生态系统是一个开放的系统,并且所有的湿地都有各自的特点,同一湿地的生态储水也会随时间发生改变,因此湿地的生态储水具有时空差异性。以九段沙为例,分析了湿地面积的变化和植被演替,以及由此而改变的湿地生态储水量的变化。
From the point of systematic ecology,the meaning of water storage in the wetland system was discussed. The water storage in the wetland system could be divided into two parts.One part included the water mainly stored in the soil or on the surface of the wetlands,which is called physics water storage.The other part was the water that stored in the body of living things.As the wetland system is an open one.And all wetlands have their respective characteristics.And the same wetland would change with time.So the water storage in the wetlands also has Spatio-temporal difference.To take Jiuduansha wetlands as a case,the wetland area change and the vegetation evolution were analyzed,at the same time,the water storage in summer for 6 years was calculated.
