The Jinshajiang River valley lies in the transition belt between the southeast edge of Qinghai Xizang Plateau and Sichuan Basin and it is a special ecological and economic zone of the upper reaches of the Yangtze River. The valley has characteristics as follows: high and steep mountains, wide range and large amount of soil erosion, sharp fall of the river branch and artery, strong scouring power, hard weather conditions, worsening ecological environment, uneasily resuming vegetation and undeveloped economy, etc. According to the spacial hiberarchy diversity and on the basis of analysing and investigating the ecological, social and economic conditions of 47 countries in the valley, this paper studies the diversity law of valley physiognomy system, weather system, forest and vegetation systems, social and economic systems and soil erosion system. All of these form the complicated and open landscape ecological system. Analysing and studying this valley is to realize the coherence between the system restoration and function requirements, and then to provide a scientific foundation for the ecological restoration of the valley.
