1芬兰北部流域内林业、农业及沉积对氮输出综合作用的模拟显示文摘本文运用了以遥感为基础的土地利用和森林分类,研究了大流域氮输出-存留空间模型N_EXRET。根据经验研究,估算了用以描述农业、林业和泥炭产量(收获)所起作用的输出系数。通过一小块集水试验区内详细记录的数据,求得林业活动典型系数。讨论了将该模型应用于奥鲁(Oulujokj)河流域(22840km^2)的模拟效果。将氮通量预估模型与在该流域不同地点测得的氮通量值进行了比较。根据资源配比,农业占总输出的17%,变动范围为8%(最高的亚流域)约38%(最低的近海亚流域)。林业约占16%,不同亚流域间变化较小(11%~24%)。在各亚流域中,所得到的氮输出总额中有7%~37%存留下来。根据质量平衡和敏感度分析,估计湖泊存留为5~10kg/hm^2·a,泥炭地为0~1 kg/hm^2·a。从三条邻近的河流流域中取得的试验数据证实了模型结论。但是,对那些土地利用和沉积格局与北部流域明显不同的流域,还需进一步研究。Ahti Lepist Kaarle Kenttmies Seppo Rekolainen 王胜 2001AMBIO-人类环境杂志2001,30,6:3
