摘要

论文根据全国水资源分区和生态功能区划的具体情况,进行了水资源三级区生态功能内涵研究,采用空间叠置法对水资源三级区图和生态功能三级区图进行叠加处理,在此基础上制定了水资源三级区生态功能确定规则,得出全国各水资源三级区的主导生态功能和辅助生态功能。然后,依据水资源三级区生态功能,确定了基于生态功能的各水资源三级区水资源开发利用率阈值。将水资源开发利用率现状与水资源开发利用率阈值进行比较,结果表明,我国水资源开发利用程度合理性呈现出明显的地域特征,东部地区合理性程度低于西部地区,北部地区合理性程度低于南部地区。

关键词： 生态功能; 水资源开发利用率; 水资源三级区; 阈值

Abstract

According to the condition of water resources regionalization and ecological function regionalization, the ecological functions of the third class water resources regions were studied. The determining rules of ecological functions of water resources regions were developed by superimposing the water resources region map and the ecological function zoning map. Based on the rules, the dominant ecological function and the assistant ecological function of each water resources region were obtained. Then, based on the ecological functions of water resources regions, the threshold value of water resources utilization ratio can be determined. By comparing the threshold value of water utilization ratio with the actual value of water utilization ratio, it was concluded that the rationality degree of China’s water resources development and utilization presented obvious regional characteristics. The rationality degree in the east area was lower than that in the west area, and it was lower in the north area than in the south area.

Key words： ecological function; threshold value; water resources regionalization; water resources utilization ratio
