This paper conducts a quantitative estimation of sustainable development status in small watershed taking Heiniuhe river as an example. Thirty-one factors were chosen from three aspects of benefit remarkability (BR), resource and environment supportability (RES) and system functional stability (SFS) and evaluation indicator was built. The mean square difference method which has a relatively high precision was introduced to ensure the index weight, avoid the subjective judgment with artificial experience and improve the objectivity and accuracy. A two-step hierarchical indicator (BR, RES, SFS) evaluation model was built using multi-hierarchical synthetic method, and a drainage system integrated evaluation model was set up using multi-objective linear weight function method. The two-step hierarchical indicator and synthetic indicator were identified for evaluating sustainable development level of this watershed. Countermeasures and suggestions specially for small watershed sustainable development were put forward.

Key words: small watershed, sustainable development, indicator system, operational stability, Northeast China
