Abstract：Zhengzhou city and Yuanyang county were selected as typical sample area of Henan province for analysis of surface water temporal and spatial distribution in different periods (1988 , 2001 and 2004) with diversity index and spatial distribution similarity ,so as to provide a new evaluation for the study of surface water spatial distribution .The results showed that ,in the same study period ,the diversity index was increasing with the size expanding of the grid area ;for smal-ler grid size ,the surface water area had some positive correlation with surface water diversity in-dex ;otherwise ,they had negative correlation .The research time interval had significant influence on the similarity of the surface water spatial distribution ,the smaller the interval of time ,the higher the similarity of the surface water spatial distribution ;the surface water area changes of the sample area also had some impact on the surface water spatial distribution similarity .
