摘要：

全球范围的城市扩张和能源消耗,导致人为热在不同时间和空间尺度上影响地表热环境,人为热排放与城市热岛的关系受到广泛关注。通过国内外文献总结源清单法、数值模拟法和能量平衡方程等3种人为热估算方法的优缺点,评价人为热研究在城市、区域和全球尺度的主要进展和区别,归纳出现有研究在城市尺度多关注人为热的时间动态变化,区域和全球尺度研究则更关注人为热的空间差异,以及人为热对于全球变暖的贡献和人类的适应对策。从中发现人为热研究中存在的问题和不足,包括研究尺度和研究方法匹配性、研究结果的验证和比较、人为热排放与景观功能的联系、人为热排放强度和周期对气温的影响机制等。根据现存问题提出多学科集成、人为热与景观功能耦合、时空尺度选择、数据获取等4个方面的建议,有助于在理论和方法方面深化和拓展城市人为热研究。
