Meeting landscape environmental water demand is one of the necessary conditions for realizing the stability and sustainablity of landscape environment. According to the characteristics of medium and small rivers in the northern cities, based on the river function, the concept of landscape environmental water demand was proposed, also its calculation method is studied in this paper. The landscape environmental water demand for medium and small rivers in the northern area can be divided into two parts according to the river functional types: environmental water demand and landscape water demand. To environmental water demand, according to river function, hydrological characteristics and water resources in different periods, the method to calculate the water demand by stages is put forward in the paper. Then integrating with landscape water demand, the landscape environmental water demand is calculated. Taking Shenyang Pu River ecological corridor as an example, it is divided into 9 sections combined with practical application and the landscape environmental water demand is calculated by the partition and staging. The results show that the landscape environmental water demand of Pu River ecological corridor is 6749.56×104 m³/year.

Abstract


Meeting landscape environmental water demand is one of the necessary conditions for realizing the stability and sustainablity of landscape environment. According to the characteristics of medium and small rivers in the northern cities, based on the river function, the concept of landscape environmental water demand was proposed, also its calculation method is studied in this paper. The landscape environmental water demand for medium and small rivers in the northern area can be divided into two parts according to the river functional types: environmental water demand and landscape water demand. To environmental water demand, according to river function, hydrological characteristics and water resources in different periods, the method to calculate the water demand by stages is put forward in the paper. Then integrating with landscape water demand, the landscape environmental water demand is calculated. Taking Shenyang Pu River ecological corridor as an example, it is divided into 9 sections combined with practical application and the landscape environmental water demand is calculated by the partition and staging. The results show that the landscape environmental water demand of Pu River ecological corridor is 6749.56×104 m³/year.
