Urban landscape in Shenzhen was affected by numerous exposed hill pits. Applying the methods of expert estimation and comprehensive assessment, by the support of the Geographic Information System (GIS), landscape impact degree of the pit was analysed. The results showed that the major facts notably influencing landscape impact degree are traffic (T), visual area (A) and distance of vision (D). Among the factors, traffic is dominating. LID based on the combinations of different factor values provided the scientific basis for the soil and water conservation and ecological environment construction of the pit.
