Investment and coordination problems of high-strength eco-environment reconstruction in Yangou Basin of loess hilly region

Eco-environment construction in the loess-hilly regions of Yangou Basin was used as a case to analyze investment structure and management of hi-speed,hi-strength eco-environment engineering in order to harness and optimize investment.Prediction and expectations of future construction investment in eco-environment are discussed.The results offer theoretic foundation for investment mechanism of eco-environment re-construction in the middle-western regions,especially the loess hilly regions.
