对会同第2代杉木林集水区的大气降水、穿透水、树干茎流水、地表水、地下水,集水区旁的小河水、水库水,县城河流水的水质进行了连续5个水文年的定位监测,研究了该集水区水质生态效应.结果表明:集水区地下水、集水区旁小河水、水库水、县城河流水之间的水质无显著性差异;大气降水中各元素含量按高低排列的顺序为K＞Zn＞Ca＞Org-N＞NH4-N＞NO3-N＞Fe＞Si＞Mg＞Mn＞P=Cu,穿透水和树干茎流水中,除Zn以外,其余元素的含量均比大气降水中的含量高,地表径流水中K、Ca、Fe、Si元素含量高于穿透水,地下水中NO3-N、P、Mg、Si元素含量高于地表径流水,而NH4-N、Org-N、K、Ca、Fe、Cu、Mn低于地表径流水;大气降...

The water quality in precipitation, throughfall, stemflow, surface runoff, and underground runoff in the secondgeneration Chinese fir plantation at Huitong Watersheds, and that in the near little rivers, the near reservoir and the town rivers, have been monitored for 5 consecutive hydrological years, and meanwhile the ecological effect of the water quality has been studied. The results indicate that the water quality shows nonsignificant deviation among underground runoff, the near little rivers, the near reservoir and the town rivers; ...
