Abstract
Abstract. With the rapid economy development and social civilization progress, the Chinese Government also is improving ecological environmental conditions. More efforts have been made to solve water problems through the implementation of stringent water resources management, as a key government policy on water. Thus, monitoring of water resources has been strengthened, being a main component of the hydrological work in recent years. Compared with routine hydrological monitoring, water resources monitoring pays more attention to the quantity and quality variations of regional waters, to reflect the status of water in river basins and administrative regions. In this paper, the overall layout of the hydrometric network in China is presented, monitoring efforts of the natural water cycle and water consumptions are analyzed, methodologies of water resources monitoring, which are commonly applied in the country, are summed up. Taking the hydrometric network planning on interprovincial boundary waterbodies as example, a summary of the planning at interprovincial boundary river sections is presented. The planning can meet the need of water resources management of administrative divisions. It can also improve the overall water resources monitoring for the country.
Highlights
Water is an irreplaceable natural resource, and an important ecological and environmental element
The amount of available waters in China per capita is about 2200 m3, only 28 % of the world average, and the volume of water per unit land area is 83 % of the world average
Land area accounts for 36 % of the country, population accounts for 40 %, and the Gross Domestic Product (GDP) is about 56 %, with 81 % of total water resources
Summary
Water is an irreplaceable natural resource, and an important ecological and environmental element. Sive situation of water resources monitoring in China, taking the hydrometric network planning for interprovincial boundary rivers as an example. The distribution of monitoring stations at interprovincial boundary river sections is proposed to meet the needs of water resources management for provincial administrative divisions. Following the implementation of stringent water management in recent years, monitoring for interadministrative boundary water sections become a new task to meet the needs of water resources management for administrative divisions. For those areas and water bodies without hydrological stations, water survey is usually carried out at a regular base, including both regional water quantity and water quality investigations
