摘　　要：根据土地利用、地形、坡度、土壤质地、地质灾害等数据进行分类筛选,通过GIS空间叠加分析得到最佳用地条件、地形地貌良好、土壤质地适宜、无地质灾害风险且靠近自然河岸的,适合建设人工湿地的用地分布情况,作为最适合区域尺度人工湿地的选址地点。以广州市为例进行分析,结果表明:(1)各区均包含适于建设人工湿地的可利用地,但主要分布在番禺、花都、增城、白云和南沙等区;(2)广州市地势北高南低,地形地貌条件较好,土壤质地粘土和壤土较多,地质灾害只有少量分布,整体用地条件较好;(3)可用于建设区域尺度人工湿地的土地主要分布在广州市的中南部,以白坭水道、流溪河下游、增江中下游、莲花山水道东岸、沙湾水道西南侧等周边地区为主。In this paper, we used the land use data, topography, slope, soil texture and geological disaster data to classify and screen the land. Through GIS overlay analysis, we got the distribution of the most suitable location for artificial wetland in regional scale which had the best land condition, well topography, suitable soi texture, no geological disaster risk and close to the natural riverbank. The results show that(1)the available lands for artificial wetland are distributed in various districts, but mainly distributed in Panyu, Huadu, Zengcheng, Baiyun and Nansha.(2)The overall land condition of Guangzhou City is good.(3)The lands tha can be used to construct the regional scale artificial wetland are mainly distributed in the south-central area of Guangzhou. They are mainly distributed in Baini waterway downstream of Liuxihe River, middle and lower reaches of Zengjiang River, east o Lianhua Mountain channel and southwest of Shawan waterway.
