中文摘要：
我国拥有极其丰富的地表水资源,可作为热泵的低位冷热源而加以利用.对全国17个典型城市的冬季十二月份地表水温进行了实测,均在2～5℃之间,指出地表水源热泵开发的关键技术是如何提取凝固热.对我国102个大中城市的地表水供应面积进行了调查统计,分别计算了这些城市的供应比例、平均供暖热需求指标、平均空调冷需求指标,并根据这三个参数对上述102个城市进行了类型化.数据表明：我国的地表水平均可为42.1%的市区傍水建筑提供低位冷热源.
英文摘要：
The surface water resource in China is rather abundant and can be used as the heat or cool source of heat pmnp. The winter surface water temperaturcs of 17 typical cities are investigated in December, and they distribute in the interval of 2 - 5℃. So the key technology of surface water heat pmnp is how to extract the freezing latent heat. The urban surface water supply areas of 102 cities in China are measured and analyzed. The supply area ratio, mean heating or cooling need index are calculated separately, and the 102 cities are classified by the three parameters. The data indicate that surface water can supply heat and cool source for 42. 1% urban waterside buildings in China.
