Highly-frequent extreme weather catches all eyes on eco-environment. A coordinated and sustainable development between human and nature is an unavoidable way to China’s high-quality development. Water transferring projects are designed to mitigate water resource imbalance among areas, and water transferring projects trans-streams may involve multiple stakeholders, that makes ecological compensation a necessary guarantee for their sustainable development. This paper, based on a case study on Niulan River-Dianchi Water Replenishing Project, establishes a gaming model, macroscopically and microscopically, to study multiple stakeholders’ gaming mechanism regarding ecological compensation situation and issues. Macroscopically, spontaneous gaming between water-supplying areas and water-receiving areas can not reach a ecologically evolutionary balance, which needs to be intervened by upper administration on complaining cost, allowance and anticipated valuation of water-supplying areas. Microscopically, evolutionary gaming among governments, firms and the public is influenced by harness fee, governmental compensation and punishment strength. Simulation of Niulan River-Dianchi Water Replenishing Project indicates an evolutionary trend of protection of Niulan River, uncompensated Dianchi, and no supervision from upper administration. Dianchi is impacted by its compensation and complaining, and upper administration is impacted by punishment fines for Dianchi and higher administration’s and costs. This paper presents suggestions on widening financing ways, improving complaining-responding system, adopting governmental supervision and control amid water-transferring projects’ ecological compensation for their sustainable development.

This paper, aiming at energy-saving-emission-reduction objective, establishes a low carbon optimized model of Hebei's energy consumption structure from economic growth, energy-saving, green-house gas emission control, energy resource abundance and technical advances, which is employed to optimize many objectives of low carbon energy consumption structure in 2020 based on Hebei's energy situation and planning. The premier energy consumption plan can not ensure the economic growth objective, the premier carbon reduction plan has higher energy consumption and lower feasibility in one-time power consumption objective, the premier energy intensity plan is a balance between energy saving and emission reduction, which makes sure the objectives of Hebei's “13th Five Years Plan” energy saving and economic growth with feasibility.

This paper, based on an analysis on land utilization and landscape pattern change, studies the tentative area in Hefei city and attains some land utilization data. Meanwhile, landscape shape index and diversity index increase while dominance index and concentration index decrease. The author gives views on some issues of land utilization and landscape pattern change in Hefei city.
