“…So the results are useful for the policy makers around the country and abroad that are making decisions regarding control strategies of environmental problems in other similar lakes. And also the results could be a contribution to the management of water conflicts between human and ecosystems [10], [11].…”

Abstract-The evolution stage classification which contains adolescence, adulthood, and old age of China rift lakes was constructed by using BP neural network model. In this paper, the model was applied to eleven lakes from Yunnan Plateau Lakes region and the middle and lower reaches of the Yangtze River plain. Through the selection of training samples, test samples and optimal number of hidden layer nodes to determine, the precision of BP neural network classification is supposed suitable for evolution stage classification of rift lakes. According to the classification results, dianchi lake is an old age lake, erhai lake, chenghai lake, xingyun lake, yilong lake, qilu lake, yangzong lake and chaohu lake are all in adulthood, and fuxian lake, lugu lake and poyang lake are in adolescence.

“…To explore the impact on habitat suitability of carp in the Yangtze River following the construction of the Gezhouba and the Three Gorges dams, a habitat suitability index model that considered the spawning characteristics of the four main carp species was established and employed by Yi et al (2010). Cai et al (2009Cai et al ( , 2010 identified optimal strategies in the planning of energy and flood management aiming at fish protection and pursuing eco-environmentally friendly operations. Based on the calculated results, a minimum instream flow and suitable daily discharge increase during the reproduction season is suggested for the protection of the carp species.…”

Abstract. The presence of elevated total dissolved gas (TDG) downstream of a spillway may result in an increased incidence of gas bubble disease in fish. Supersaturated TDG is transported and dissipated more slowly in reservoirs than in natural rivers because of a higher water depth and lower turbulence and thus endangers fish. This paper presents the operational regulations concerning the mitigation of the TDG supersaturation impact on fish in the Bala Reservoir on the Zumuzu River. The paper includes the joint operations of the upstream and downstream power stations. A laterally averaged two-dimensional model is employed to simulate the TDG transportation and dissipation in the Bala Reservoir in addition to the hydrodynamics and water temperature. According to a comparison of the simulation results of different operational scenarios, this paper suggests a regulation scheme. With respect to the upstream power station, the adoption of an interval-discharge pattern instead of a continuous-discharge pattern is recommended to minimize the negative effect on the reservoir caused by supersaturated TDG. With respect to the downstream power station, the adoption of a surface tunnel rather than a bottom tunnel is recommended as a release structure. This paper is a reference for the eco-environmentally friendly operation of large and deep reservoirs.

“…Such situations have forced decision makers to contemplated and proposed comprehensive and ambition plans for managing and planning energy systems. However, such planning efforts are complicated with a variety of processes that should be considered by decision makers, including energy production, supply, import/ export, conversion, transmission and consumption [6]. It is necessary to develop effective optimization methods for supporting energy system planning under such complexities.…”

a b s t r a c tAn interval-fuzzy municipal-scale energy model (IF-MEM) is developed for energy systems planning. IF-MEM can effectively tackle uncertainties presented in terms of fuzzy sets and discrete intervals. IF-MEM is applied to a real case of energy systems planning in the City of Tianjin, which is the economic and industrial center of northern China. IF-MEM allows in-depth analyses for tradeoffs among economic objective, satisfaction degree, and constraint-violation risk. The results indicate that reasonable solutions have been generated. The results suggest that: (i) coal would be the dominant sources in city's energy systems due to the increasing energy demand; however, its consumption ratio would decrease over the planning horizon due to requirements of environment protection and sustainable development; (ii) clean (e.g., natural gas, liquefied petroleum gas) and renewable energies (e.g., wind power, solar power) would be vigorously encouraged during the planning periods; (iii) coal-fired technology (i.e., coal-fired power and heat) would be the major contributor for the city's atmosphere pollution; (iv) the pollutant emissions would be decreased over the planning horizon due to the restriction of fossil fuels and the development of renewable energy. Promoting the utilization of renewable energy sources is crucial for supporting pollutant emission reduction and solving energy shortage crisis.
