Urban wetland parks (UWPs) play important roles in human daily life, particularly on supplying recreation services. However, rapid urbanization results in much loss of UWPs, that may aggravate human living environment. How to balance recreation services supply from UWPs and human needs on recreation become an important issue. In this study, the affecting factors of UWPs utilization in term of recreation, the supply on recreation service from UWPs and human demand on recreation in Beijing were addressed. First, it was found that distance decay is found on resident's using UWPs. Generally, the more time requires to reach, the less the UWPs are visited. The affecting factors on using UWPs for recreation are: distance, income, transportation, education, occupation, and age. Second, the serving radius of Beijing UWPs is about 37.5 km, and decreases from the downtown to the suburb. Supply capacity of UWPs on recreation was calculated based on interview data. Third, age and income are the main affecting factors of resident's needs on recreation, and declines from the downtown to the rural area. The total demand on recreation of UWPs in Beijing was estimated by using census data. Fouth, It was found that about more than 50% of administrative areas has a high accessibility to the UWPs in Beijing by overlaying the supply capacity and demand on UWPs in term of recreation services. Based on the above results, a conceptual framework for balancing the demand and supply on UWPs for a pleasant living environment was proposed.
