摘　　要：为了提高森林水文研究过程中数据采集的精确性,应用现代测绘技术,包括水准测量、全站仪三维坐标测量、GNSS卫星测量及测深仪的水深测量等,研究了广州南香山水库的库容变化规律,反演水库上游森林径流。研究结果表明:南香山一年内的降雨量分布出现类似双波浪形的变化,波峰出现在5月份和8月份,波谷出现在1月和10月;降雨量与库容增量存在线性关系,相关系数为0.915 2;地表径流的大小主要与植被类型,土壤水分的饱和度及地形有密切关系。相比传统的测量方法,现代测绘技术更精确地反映了广州南香山地区森林水文的变化规律。In order to improve the accuracy of the data acquisition in forest hydrology research process, this paper studied the change law of reservoir capacity and inversion of the forest runoff data in reservoir upstream on Guangzhou Nanxiangshan Reservoir through the application of modern surveying and mapping technology, including leveling, 3D coordinate measurement based on total station, GNSS satellite measurement survey. The results of the study showed that： the rainfall distribution on Guangzhou Nanxi and sounder bathymetric angshan Reservoir within one year changed similar to the double wave shape. The peak appeared in May and August, and the trough appeared in January and October. There was linear relationship between rainfall amount and capacity increment, and the correlation coefficient is 0.915 2. The size of surface runoff has the significant relationships among the vegetation type, topography and soil water saturation. Compared with the traditional measuring method, the modem surveying and mapping technology is more accurately which reflected in the variation of forest hydrology in Guangzhou Nanxiangshan Reservoir area.
