| 摘 要： | 对秦岭辛家山锐齿栎林生态系统对水质的影响进行了探讨，结果表明：锐齿栎林生态系统对水质具有净化作用，并以林冠层的净化作用为最强，效应指数达－５２．４％，枯落物层次之，效应指数为－６．６％，以土壤层最弱，效应指数为－１．０６％；对水质的评价表明，该地区大气降水的水质为轻污染（质量指数为０．９０５９），以迳流的形式输出系统时的水质为微污染（质量指数为０．３０４４）。

| Abstract: | The results indicate that the sharp-tooth oak forest ecosystem has a purificatory effect on the water quality,the purificatory effect of the canopy layer is strongest and then is that of the litter layer while that of the soil layer is weakest,their effect indexes are -524%,-66% and -106% respectively,the water quality of the precipitation in this area is lightly polluted (the quality index is 09059)and the quality of the water drained from the ecosystem as the runoff is minutely polluted(the quality index is 03044) |
