摘  要：
以遥感、土地利用、气象以及绿地统计资料为主要信息源 ,利用GIS空间分析技术 ,对 2 0 0 0年以来上海中心城区热岛效应与绿地分布状况进行动态监测和综合评估。得出初步结果和结论为 :(1)上海从 2 0世纪 80年代起热岛效应明显扩大和强化 ,而城市的发展更强化了热岛效应。 (2 )城市绿化可以缓解热岛效应。科学规划和大力发展城市绿化建设可以产生“绿岛效应”。从延中绿地的作用看 ,集中的、大范围的绿地建设缓解热岛效应的效果明显。 (3)上海由于加强了城市绿化规划和建设 ,已经使夏季城市热岛效应的增强趋势得到初步减缓。中心区的热岛效应强度有所降低 ,特高温区有了减少。 (4)上海城市的地表热力状况若要恢复到 2 0世纪 6 0～ 70年代的水平 ,不仅需要进一步加强城市绿化规划建设与管理 ,还要继续加大绿化科学规划和建设力度

摘  要：
Based on main information sources from remote sens ing, the land utilization, and the statistical data from meteorology and green l ands, a dynamic monitoring and comprehensive evaluation on the heat island effec ts and the situation of greenbelt distribution has been made by use of GIS spati al analytic technique. The preliminary results are as follows. (1) The heat isla nd effect of Shanghai has been expanding and strengthening significantly since 1 980s,and the development of the city makes the effect much stronger. (2) Urban a fforestation can reduce the heat island effect. Scientific plan and development of urban afforestation can create "green island effect". According to the eff ect by the Yanzhong green land, a concentrated and large scale construction of Greenland can appreciablely reduce the heat island effect. (3) The trend of incr easing heat island effect in summer has been initially checked because of reinfo rcing the plan and construction of urban afforestation. The heat island effect i s decreasing in center downtown, and the number of extremely high temperature zo nes is also decreasing. (4) In order to restore the surface thermal condition fo r Shanghai to that in the 1960s and 1970s, the plan, construction and management of urban afforestation should be further reinforced.
