摘　　要：随着旅游业的不断发展,景区环境污染问题越来越突出。采用系统聚类分析方法,通过环境污染要素指标数据,对天河潭区域(37个村和1个景区)环境污染程度的距离相似情况进行评价。结果表明:天河潭景区污染程度最为严重,归为第三类聚类;其次是围绕景区附近的22个村,归为第二类聚类;第一类聚类有15个村,分布在第二类外围。造成该区域污染状况的主要原因:1)景区内游客人数较多,且不断增加;2)畜禽养殖场的排放物未有效处理;3)生活垃圾堆放和回收设施不完善。Environmental pollution became more and more highlighted in tourism development in the scenic spot. Indicators of environmental pollution were selected to assess the environmental pollution degree of Tianhe Lake area（ 37 villages and one sight spot） with the method of hierarchical cluster analysis. As a result,three cluster were revealed. The third cluster involved the sight spot,the second cluster involved 22 villages,and the first cluster involved 15 villages. There were three reasons for this： 1） The number of tourists was high within the area,and the number of visitors was increasing; 2） emissions from livestock and poultry farms were not effectively addressed; 3） recycling installations of life garbage were not perfect.
