title: [Study on spatial site selection assessment of urban medical waste treatment facility].
abstract: Based on the principle of regional differentiation and gravity model, this paper proposes a GIS-based urban medical waste treatment facility spatial site selection assessment method. And the method is implemented by use of the third generation GIS database model, Geodatabase. Taking a city in Pearl River Delta as a case, based on its 46 basic units, two scenarios for medical waste central treatment are designed and analyzed by means of scenario analysis (SA) and then the better scenario is recommended. The assessment result of traditional cost model shows the same conclusion. Further spatial analysis shows that the distribution of medical waste quantity and density are both related to the better scenario spatially.
