On Apr. 27, 2017, MWR Department of International Cooperation, Science and Technology (DICST) organized an acceptance meeting to assess the MWR public-good research project “Simulation of Stringent Water Resources Management System and Control Technology of Water Consumption Structure” in Beijing. The expert panel consisted of experts with MWR, Tsinghua University, China Institute of Water Resources and Hydropower Research, Changjiang River Scientific Research Institute, etc. Deputy Director JIN Xuhao with DICST and colleagues from NHRI Department of Research Management and project team attended the meeting.
The project adopted a research approach of combining water science with economics and management. The following major achievements were made after 3-year research.
1) Revealing the variation characteristics of quantity, quality and effect management indicators (i.e. total water consumption, water consumption per 10000 Yuan industrial added value, effective utilization coefficient of farmland irrigation water, and water function zone compliance rate) with incoming water and social and economic development. It was the first time to propose the interaction diagram of the indicators and discuss the compatibility and completeness of the "Three Red Lines".
2) Setting up the sub-industry and hierarchical driving factors recognition models which identify the key driving factors and provide the basis for the system simulation and selection of regulatory factors to implement the "Three Red Lines" based on the attribution of the variation of quantity, quality and effect management indicators to incoming water and social and economic development.
3) Constructing a model system of stringent water resources management system which analyzes the dynamic changes of quantity, quality and effect management indicators, and provides a model support for the implementation and assessment of the "Three Red Lines" based on the regional macroeconomic model, water demand and pollutant emission model, supply and demand balance model of a catchment and water quality compliance rate model in water function zones of a catchment.
4) Developing the transition relationship between the control target of the "Three Red Lines" and annual management targets varied with the frequency of annual available water or annual precipitation, simplified conversion method of annual management targets of total water consumption, and coordinated regulation model of industrial structure and water consumption structure under the constraint of the “Three Red Lines” so as to provide technical support for appropriate industrial restructuring programs and strategies.
5) Developing a digital simulation lab of the stringent water resources management system in Shandong Province integrating the system simulation, scenario prediction, dynamic regulation and assessment with the help of B/S framework so as to provide decision-making tools.
The research findings have been systematically applied in the formulation and perfection of assessment of stringent water resources management system in Shandong Province, in the implementation and assessment of the “Three Red Lines” at provincial and municipal levels in Shandong in 2015 and 2016, providing supports for the important planning of Shangdong Province such as the medium and long term planning of integrated water resources utilization.
27 papers relevant to the project were published in the mainstream journals of water resources management, such as Journal of Water Resources Planning and Management, Water Resources Management, Water Policy, Journal of Hydraulic Engineering, etc. Two books of Study on Evolution and Control of Regional Water Consumption Structure and Simulation Model of Stringent Water Resource Management System and Its Application were published as well. 1 software copyright was authorized, and 13 post-doctors and postgraduates trained.
The expert panel unanimously agreed that the research tasks had been comprehensively fulfilled with abundant research findings, remarkable economic benefits, promising prospect of promotion and application, outstanding progress and expected goals after carefully listening to the results report. The project smoothly passed the acceptance check with an excellent score.
