Abstract: The effect of consumption of water resources on economic growth is considered from the aspects of water consumption and structure. The magnitude of damping of water resources on the economic growth of five provinces in Northwest China is measured by using the improved C-D production function and the Romer damping analysis model from the aspect of the third industry, and the coefficient of structural deviation is used to measure the dynamic changes of consumption structure of water resources and industrial structure. From the consumption of water resources, the output elasticity of capital and technology of the third industry of five provinces in Northwest China is greater than that of labor and water resources, indicating that the economic development in the northwestern areas is strongly dependent on the capital and technology. And there are more areas with growth damping for the second industry, which means the second industry is more dependent on water resources. From the perspective of structure of water consumption, the allocation of water resources basically reaches the optimal efficiency between the second and third industries, but the distribution between the first and second and that between the first and third industries are uneven. The structural changes in water consumption lags behind those in industrial structure, and the consumption structure of water resources and industrial structure are not coordinated. Based on these results, some policy proposals are put forward as follows: increase of water use efficiency in various areas, decrease of water consumption, improvement of water use structure, and promotion of water resources towards the second and third industries.

Abstract: Quantifying the relation between industrial water use and economic growth is of great significance to industrial water saving. Taking the period from 1998 to 2015 as the research one, the PVAR model and VAR model are employed to study the relation between industrial water use and economic growth of the whole region and various provinces and cities in the east areas of China. The results of PVAR model show that there is a long-term coordinated relation between industrial water use and economic growth. One-stage lagging of the industrial water use has great positive effect on the industrial economic growth. The response of industrial water use to disturbance of industrial economic growth exhibits an inverse U process, that is, it first increases and then decreases. The water resources gradually restrict the industrial economic growth. The fluctuation in the industrial water use is mainly resulted from itself and slowly decreases. The effect of industrial water use on the industrial economic growth is gradually strengthened. The results of VAR model indicate that the VAR model cannot be established in Shanghai City and Fujian Province, and the results of VAR model, pulse response analysis and variance decomposition in the other provinces and cities are greatly different, indicating the necessity of researches of VAR model for various provinces and cities. Therefore, the PVAR model and VAR model should be combined, and different and specific policies of water resources should be formulated according to the local situations so as to form the beneficial cycle between the utilization of water resources and industrial economic growth.

Abstract: The pilot demonstration of water rights is taken as the research object under the background of carrying out the reform of water rights at all levels in China. According to the general needs of construction work of water rights and water markets and following universal, scientific, integral, purposive and dynamic principles, a four-level deformation evaluation system is established, which takes five pieces of reform work of water rights, “right confirmation work”, “water market construction”, “organization and supervision”, “infrastructure construction” and “reform and innovation”, as the standard layers. And then the weight of each index is assigned by AHP, and the Delphi method is used to score the second-level indices. The evaluation system is used to evaluate the two typical pilot projects of water rights in Shandong Province. The quantitative evaluation of reform of water rights in these two places is obtained after revising the results according to their respective pilot tasks. The proposed evaluation method is not limited to the evaluation of the pilot areas, and it can be used to evaluate the general performance of work of water rights in the future.

School of Water Resources and Hydropower, Sichuan University, Chengdu 610065, China; 3. China Renewable Energy Engineering Institute, Beijing 100011, China)

Abstract: The determination of pollutant reduction cost in the ecological compensation method for pollutant flux neglects the differences in various pollutant sources, and the estimation of pollutant flux does not consider the actual hydrology and characteristics of water quality within a year. Hence, the above method is improved based on the two aspects, namely, the cost of pollutant reduction and the total amount of pollutant discharges. The pollutant reduction costs are divided into two parts: point sources (mainly industrial wastewater, urban domestic sewage) and rural non-point sources (mainly rural domestic sewage, agricultural production sewage). The final costs of reduction are weighted according to the proportion of pollutant emissions. At the same time, the water period within the year is divided, and the flux of pollutants is calculated separately. A case study is carried out to validate the proposed method in the buffer zone between Chongqing and Sichuan on Laixi River, a branch of Tuojiang River. The results indicate that the calculated amount of compensation can essentially reflect the regional pollution characteristics and it is more realistic and credible,

Abstract: In order to analyze and evaluate the sustainable development level of water resources in Wuxi City, a comprehensive evaluation model for the sustainable development of water resources is established based on the model for calculating the ecological footprint and carrying capacity of water. This model includes three indices: ecological profit and loss of water, ten-thousand yuan GDP ecological footprint of water and ecological sustainability index of water. Combined with the ARIMA model, the sustainable development trend of water resources in Wuxi City is predicted. The results show that during the period from 2008 to 2015, the water ecological footprint of Wuxi City increases with fluctuations, and that of ten-thousand yuan GDP decreases year by year. Except for the water ecological deficit in 2013, the water resources are in a weak and unsustainable development state. In other years, the ecological carrying capacity of water is slightly greater than the water ecological footprint, and the ecological sustainability index of maintained in the rage of 0.55 to 0.66, which is in a weak and sustainable development state. If the current mode of water resources utilization is maintained, it can be predicted that the water ecological footprint of Wuxi City will increase year by year from 2016 to 2020, and the ecological sustainability index of water will be in a risk of falling to a weak and unsustainable level.

Abstract: Based on four types of indices of management rules, management implementation, management support and management effectiveness, a questionnaire survey is conducted involving 181 Chinese national water parks (abbreviated as CNWPs) to assess their management performance. The results demonstrate that 181 CNWPs have an average score of 58.4, and 54.7% of them have a score below 60 of the total score, illustrating that their general management performance is relatively low. There is a significant difference in the scores of the management performance among CNWPs with different types, established time, regions, economic levels, main functions and institutional independence, while there is no significant difference among CNWPs with different areas and types of business. The average scores of the management implementation are the lowest than those of the other three types of indices. From the whole factors, the scores of the land ownership, control of tourists, layout of catering and lodging, management plan, green performance appraisal, utilization of bio-toilets, community participation, resource censor, protection fund, environmental propaganda, environmental training and operating conditions are lower than the average ones. The following suggestions are proposed: reform of management system, implementation of classified management system, exploration of ecological compensation of inter-basin, marketization and multi-function, implementation of the franchise system, strengthening of supervision over natural protection and improvement of the system of natural protection.
