Abstract: The rapid process of urbanization in China is suffering from environmental pollution, traffic congestion, housing shortage and a series of urban problems. Urban ecological environmental quality continue to decline. The urban green landscape plays an important role in the balance of carbon and oxygen. Developing the urban greening vigorously will help to improve the urban environment. But at present, in our country, there is a lack of specific spatial distribution planning in city green space construction. Cities focuse only on the green coverage rate and green space of human settlements but pay less attention in the fairness of green space service function. This paper researches on the green space accessibility of Shahekou District in Dalian City by ArcGIS. By comparing the green space accessibility and the type of human settlement environment in Shahekou District, we found that high-income social groups have a higher green space accessibility than the low-income social groups. City planners should be aware of these issues and concern all sectors' need of green space in the future construction, so that urban residents can enjoy a more equitable public service resources.

Key words: urban green space, fairness, green space accessibility, Dalian
