Initial allocation of stream water discharge right is a key factor in water right exchange mechanism, and a basis in promoting a fair water discharge and sustainable development. This paper, based on the research advances on rare resources allocation, presents an initial allocation model of water discharge right based on chaos optimization-projection pursuit by means of initial allocation methods of water right and waste water discharge right. Projection pursuit can avoid subjective evaluation, sample-driven optimization is more objective. Initial allocation proportion of water discharge right is finally determined through chaos optimization which is used to calculate the premium projection. Case study on Jiangsu section of Huaihe stream validates this method feasible, which covers historical loss, economic development and ecological environment that plays a leading role. The initial allocation proportion of central Jiangsu in Huaihe stream is generally higher than northern Jiangsu.

 Exploring the transformation of coal independent mining area is a vital task in the macroscopic environment of reducing coal production and transformation. This paper, based on a case study on Shenjiazhuang coal mine in Ci county, uses sustainable development theory which is based on generalized earth system theory and onsite investigation to analyze the issues in mining area, such as sole industrial structure, striking dual mine-country structure, worsening eco-environment, group conflicts and employments, and presents suggestions in coordinated development of three industries, overall mine-country planning, improving environment, multi-participated transformation and rational employment, aiming at a successful transformation of sustainable development in coal independent mining area, which is of value in reducing coal production, promoting mine-country united development, optimizing industrial system in mining area, improving eco-environment and stabilizing social order.
