| 中文摘要 |
| 以地域分异规律和吸引力模型为理论基础,提出基于GIS的城市医疗废物处置设施选址的空间评价模型,利用第三代GIS地理数据库模型Geodatabase实现了该方法.以珠江三角洲某城市为例,将该市划分为46个镇级基本单元,应用情景分析方法生成了医疗废物集中处置的2个空间选址方案并进行了空间评价;为了进行对比分析,还构建了传统的费用模型进行了评价,两者结果一致.进一步的空间分析表明,该市医疗废物数量空间分布和密度空间分布和较优方案具有空间相关性. |

| 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. |
