摘要：在浙江省安吉县赋石水库库尾选择有代表性的板栗(Castanea mollissima)林地设置径流小区,对自然降水条件下地表径流中污染物的流失特征进行观测、研究。结果表明:2012年3-10月共观测到10次产生地表径流的降雨事件,降雨量从28.2mm到303mm不等;径流水中TN、NH4+-N和COD浓度与降雨量均呈现显著正相关(p=0.05),TP浓度与降雨量则呈现显著负相关(p=0.05),而NO3--N与降雨量之间没有表现显著相关性;污染物浓度COD(6.12～11.14mg/L)>TN(2.163～5.371mg/L)>NH4+-N(0.733～4.220mg/L)>TP(0.276～1.742mg/L)>NO3--N(0.035～0.433mg/L)。这些结果表明,单一经营的板栗林地表径流污染物中N、P浓度均超过引起水体富营化的阀值,对水库面源污染和水质变化形成潜在压力。
The research on characteristics of soil erosion pollutants under the conditions of open field was conducted with selecting typical chestnut（Castanea mollissima） stands and setting up runoff plots in downstream area of Fushi Reservoir in Anji county of Zhejiang province.The results showed that there were 10 runoff events which had been observed with the range of rainfall from 28.2 mm to 303 mm during March and December in 2012.The concentrations of TN,NH＋4-N and COD all had positive correlations with rainfall amount（p=0.05）,while TP had negative correlation with rainfall amount（p=0.05） and NO-3-N had no correlation with rainfall amount.The order of pollutant concentration was COD（6.12～11.14 mg/L） TN（2.163～5.371 mg/L） NH＋4-N（0.733～4.220 mg/L） TP（0.276～1.742 mg/L） NO-3-N（0.035～0.433 mg/L）.The results indicated that concentrations of N,P under monoculture of chestnut stand were both higher than the threshold of causing water eutrophication,and had a potential stress to give rise to nonpoint source pollution around the reservoir.
