摘要
研究全面收集了全国31个省、直辖市、自治区的河流、行政区界、水文测站等基础信息,较为客观系统地分析了目前我国县级及以上行政区界水资源水量监测的现有覆盖率、潜在覆盖率和目标覆盖率。结果表明,各省县级以上行政区界现有水量监测能力普遍不高,平均覆盖率仅为40.9%,空间上呈现东南地区覆盖率较高,西北地区较低的特征;考虑有条件实现水量监测的可开展监测断面数量,目标覆盖率除了西藏、新疆、宁夏、黑龙江和青海这五个省份较低外,其余省份均能达到70%以上。研究成果将为跨界水资源管理考核、行政区界站网规划、水利基础设施投资估算等提供数据支撑。
This paper collected the basic information of rivers,administrative boundaries and hydrological stations of 31 provinces,municipalities and autonomous regions in China,and analyzed the existing coverage rates,potential coverage rates and target cover-age rates of water resources and water quantity monitoring above county level.The results show that the existing water monitoring capacity of each province is not high,and the average coverage rate is only 40.9%.In space,the coverage rates of southeast re-gion is higher than that of northwest region;Considering the number of monitoring sections that can be carried out for water quan-tity monitoring,the target coverage rates can reach more than 70%except Tibet,Xinjiang,Ningxia,Heilongjiang and Qinghai provinces.The results could provide data support for the assessment of cross-border water resources management,hydrologic net-work design of administrative boundary and investment estimation of water resources infrastructure.
