摘要：对浙江省庙山坞自然保护区天然次生常绿阔叶林的水文生态特征进行了为期1a的定位观测研究。结果表明:(1)研究区天然次生林土壤水分具有明显月动态变化规律和垂直变化特征,土壤含水量年均14.24%～22.55%,年内变化与降雨量趋势基本一致,为先上升后下降。表层(0—5cm)土壤水分垂直变化较大,随着深度的增加,森林土壤含水量变异系数减小。(2)坡面径流量月变化较大,与一次性降水有密切关系。集水区径流量月际间变动幅度较大,8月份径流量达到最大值389.11mm。(3)流域内的多次水质抽样检验结果表明,多数水质指标都达到一类水质标准,超标指标主要是总氮和pH值。
The eco-hydrological characteristics of natural secondary evergreen broadleaved forest in Miaoshanwu Nature Reserve were studied based on field observations within a time period of one year.The results show that soil moisture of natural secondary forest has significant temporal and spatial variations.The average annual soil moisture content ranged from 14.24% to 22.55%.Similar to precipitation,soil moisture content increased firstly and then decreased during a year.Soil moisture of the surface layer（0—5 cm） exhibited strong variability.With the increase of soil depth,the coefficient of variation of soil water content decreased.Strong variations of monthly slope surface runoff were observed and were found closely correlated with single-event rainfall.In the watershed scale,monthly surface runoff varied in a wide range with a maximum runoff of 389.11 mm in August.The results of water quality sampling show that most water quality indices qualified the first level in the governmental standards,except for total N contents and pH values.
