A STUDY OF COUNTY PUBLIC SERVICE FACILITIES DISTRIBUTION ASSESSMENT BASED ON BEHAVIOR INVESTIGATION AND GIS:A CASE STUDY OF MEDICAL FACILITIES IN DEXING

On the specific operation, this paper puts forward a four steps approach. First of all, a hierarchical structure of county public service facilities should be established, which generally contains three- tiered system at county-township-village. Secondly, we should calculate the facilities' spatial accessibility. Here we use commuting time instead of spatial distance as a measuring standard and consider the road network and travel mode, more in line with the actual situation of the county. Thirdly, we divide the actual service area based on the travel map analysis, which can reflect the residents' independent choices and cross- regional movement on account of the quality differences among the service facilities. The researchers can find the places where the cross-regional movement phenomenon is apparent and analyze the cause. At last, according to the actual service area, we can do further evaluation of the service facilities' quality, efficiency, availability and so on, which help to find the do a better public service facilities planning.
