Abstract: In the background of the protection of Yangtze River, realizing high-efficient development of green ecology should be taken as part of the high-quality development of the Yangtze River Economic Belt.Therefore, focusing on the evaluation and improvement of hydropower energy efficiency in Yangtze River and comprehensively considering social, economic and environmental factors, an input-output index system is established.Based on the hydropower-related panel data of the various provinces along Yangtze River Economic Belt from 2008 to 2017, the DEA method is used to evaluate the hydropower energy efficiency of each region.The results show that the hydropower energy efficiency of Yangtze River Economic Belt is at high level as a whole, and Jiangsu Province and Hubei Province are the “benchmarking” regions.The index efficient score of the urban agglomeration in the middle and upper reaches of Yangtze River is generally high.Different provinces have different energy efficiency improvement directions, that is, Jiangsu Province and Zhejiang Province should reduce the investment in human capital, while Anhui Province and Jiangxi Province should increase the equipment utilization hours of the installed hydropower, and Chongqing Municipality and Guizhou Province firstly should develop local economy with high quality and improve the rate of return of the fixed asset investment.Some suggestions are put forward: development of hydropower with high quality, rigid constraint of water resources, establishment of green hydropower certification system, improvement of investment subsidy system, optimization of the balance between supply and demand, and training of high-level talents.

Abstract: During the key stage of winning the decisive well-off society, it is crucial to maintain and strengthen the strategic willpower of ecological civilization construction.Based on the pressure-state-response(PSR)model, an evaluation index for the strategic will power of ecological civilization construction is established, including 17 indices and 3 subsystems, that is, pressure of ecological protection, state and capacity of ecological civilization construction.The strategic willpower of ecological civilization construction and the coupling coordination degrees of ecological civilization strategy in 2017 are empirically evaluated in 30 sample cities in China by using the main component analysis method.Based on the evaluation results, the regional differences of the strategic willpower of ecological civilization construction in the major cities of China are analyzed, and some countermeasures are put forward to further maintain and strengthen the strategic willpower of ecological civilization construction.

Keywords: ecological civilization construction; strategic willpower; PSR model; coupling coordination degree

Abstract: It is the crucial direction of urban development in China to promote the sponge city construction, to realize pattern transition of urban construction and to alleviate urban water problems.Thus the sponge city construction has become one of the hot issues in the field of urban construction governance and attracted much attention.At present, the sponge city construction in China confronts problems of “fragmented phenomenon”, including difficulty in coordination among different participants, fragmented policies and systems and backward construction methods.In this case, complex urban water problems cannot be effectively resolved.Based on the analysis of the main performance and its causes of “fragmented phenomenon” of the sponge city construction and the lessons learnt from the experience in Zhenjiang, some suggestions for solving the “fragmentation phenomenon” of sponge city construction are proposed from the perspective of construction management system, governance mechanism and legal system.

AssessmentmodelforregionalfloodrisksbasedonANP-PP-SPA/LI Wanyu1, HUANG Xianfeng1, JIN Guoyu2, FANG Guohua1, SHI Zhikang1(1.College of Water Conservancy and Hydropower Engineering, Hohai University, Nanjing 210098, China; 2.Kunshan Water Group Co.,Ltd., Kunshan 215300, China)

Abstract: The flood risk assessment is an important basis for formulating the corresponding flood control and disaster reduction measures and plays an important role in the safety and protection of people’s lives and property.In view of the deficiencies and shortcomings of the existing assessment models for flood risks, an assessment system for flood risks is established from the four aspects of disaster-causing, disaster-breeding, disaster-bearing and disaster mitigation through analysis and calculation of 14 evaluation indices.The subjective and the objective weights are solved by using the analytic network process(ANP)and the projection pursuit(PP), respectively.An assessment model for flood risks based on ANP-PP-SPA is established by coupling the subjective and objective weights with the set pair analysis(SPA).Taking Yingde City of Guangdong Province as an example, the applicability of the assessment model for flood risks is verified.The results show that the flood risk grade of 2016 in Yingde City is medium, which accords with the actual situation of 2016 in Yingde City.The assessment model considers the relationship among the indices and reflects the ambiguity and randomness of flood risks, and it can provide a scientific basis for the regional flood risk decision-making and the flood management.

Abstract: The government’s retained water quantity of water right of Yellow River in Inner Mongolia has not been allocated through neither the initial water right nor the water right transaction.It does not match with the reality of the protection of ecological environment, construction of major projects and development of water right transaction in the regions in Inner Mongolia along the Yellow River.Therefore, it is proposed that the government’s retained water quantity of water right of Yellow River in Inner Mongolia should be allocated by the administrative or market means.At the same time, the vertical management mode combining the basin management with the regional management is implemented, and it is adjusted in time.

Abstract: To further reduce flood damages and to solve regional drainage disputes, on the basis of exploring the connotation of the flood drainage right, it is concluded that the flood drainage right is mandatory, exclusive, tradable, variable and urgent.The WSR analysis framework for the allocation of flood drainage rights is established by using the WSR system method.It is regarded that the allocation of flood drainage rights is subjected to physical, reasonable and artificial factors.The functions of the above factors are analyzed during the allocation process, and an index system for the initial allocation of regional flood drainage rights is established.This will help to systematize and stratify the driving factors for the effective initial allocation of flood drainage rights so as to provide the reliable basis and the decision-making of flood control and to play a supporting role in guaranteeing the safety of flood control and realizing the social fairness and regional sustainable development.
