By using hiberarchy analysis and comprehensive index method, the ecosystem service importance and its regional diversities in Liaoning Province were quantitatively assessed, based on the comprehensive analysis of biodiversity protection, water resources conservation, soil conservation, desertification control, and nutrients conservation. Overall, the ecosystem service in the Province was in importance. 60.66% and 30.71% of the total area of Liaoning Province had the ecosystem service in high and medium importance, respectively; while the rest had the one in certain extent importance.

In order to accelerate the harmonious development of regional economic and ecological environment,ecological function regions were divided in Liaoning province based to the actual status.It could be be divided into 4 ecological regions,15 ecological subregions and 47 ecological function regions.At the same time,the key regions based on ecological service function were determined.

Based on the formation mechanisms of the main eco-environmental problems in Liaoning Province,this paper studied the regional differentiation patterns of ecosystem sensitivity,and analyzed the sensitivities of manifold eco-environmental problems in the Province.The results showed that the areas of high,medium,and low ecosystem sensitivity in the Province occupied 34%,62.66%,and 3.34 % of its total terrestrial area,respectively.High ecosystem sensitivity area mainly distributed in east Liaoning mountainous region,Liaodong peninsula,west Liaoning hilly region,northwest Liaoning,Liurao area,and Dawa County,among which,east Liaoning mountainous region,Liaodong peninsula and west Liaoning hilly region were of high sensitivity on soil erosion,northwest Liaoning and Liurao area were of high tenderness on desertification,and Dawa County was delicate in soil salinization.

Based on the analysis of the basic eco-environmental characteristics of Liaoning Province,and by means of remote sensing,Geological Information System(GIS) software,and comprehensive analysis methods,this paper made an ecological zoning of this province on three levels,namely,ecological zone,ecological subzone,and ecological function zone.There were 4 ecological zones,21 ecological subzones,and 52 ecological function zones in Liaoning Province,named by three-structure method and mapped out,which provided theoretical bases for reasonable natural resources utilization,industrial and agricultural layouts,and sustainable development in this province.
