摘要:
 根据南京毛竹林小流域降雨径流数据的观测分析，毛竹林具有良好的水源涵养功能；毛竹林小流域月降雨量分别与月径流量、月壤中流+地表径流、月基流量、月产损呈正相关，降雨是影响该地区径流年际变化的主要因素；结合SCS模型反推得到的CN值计算式，分析表明：在产流过程中，CN值与土壤体积含水量无相关性，CN 值分别与降雨量、降雨量/土壤含水率呈指数负相关，与产损量呈负相关关系，并建立CN值与各显著影响因子的回归模型。此结果可为日后SCS模型在该流域的应用提供参考。
Abstract:
 Based on the analysis of the data from the observation of rainfall and runoff in Nanjing moso bamboo forest watershed, it was found that Phyllostachys edulis forest had the good function in water conservation. Monthly rainfall in the watershed was positively correlated with the monthly runoff, monthly interflow + surface flow, monthly base flow, and monthly capacity loss, respectively. According to the CN value calculation formula from the SCS model, we analyzed the relationship of CN value with rainfall, soil volumetric water content, and rainfall/soil volumetric water content. The CN value had no correlation with the soil volumetric water content, it had significantly negative exponential function correlation with rainfall and rainfall/soil volumetric water content, and negatively correlated with capacity loss. The regression model with CN values and various significant impact factors was established. The results would provide references for the application of the SCS model to the watershed area in the future
