水资源存量及变动表相关技术问题解析

Interpretation of technical issues in physical asset account for water resources

针对水资源存量及变动表中存在的一些技术问题,如水资源存量的意义及指标确定、降水形成的水资源与地表水和地下水资源关系、各类水体之间的转换与平衡关系、河湖生态耗水量的含义等,通过建立一套假定条件,基于相关技术标准和规范,结合具体实例,对这些问题加以剖析,以期使该表能够得到更好理解和应用。

Focusing on technical issues in physical asset explanation and interpretation on them with a practical account for water resources, this article proposes detailed example in a northern city of China by setting several assumptions and based on relevant standards or criterions. These issues may include the connotation and quantification of water resources stock and its changes, the relationship between annually renewable water resources with surface and ground water resources,＇ the transmission of various water bodies and its balancing, ecological water assumption from rivers and lakes, etc. It is hoped to give some assistance to those who engage in formatting the account.
