汉中站-
在汉江汉中站集水区域植树造林将可能使年均蒸散发量增加2.1%～11.1%，年均径流量减少1.3%～7.5%，可以有效地削减洪峰流量、延缓洪峰；
Results also show that afforestation in the Hanjiang River basin might raise evapotranspiration by 2.1-11.1 % and reduce runoff by 1.3-7.5 % , and cut down and delay flood peaks effectively .

选取汉江上游汉中水文站以上集水面积为研究区域，基于栅格型数字高程数据，利用数字高程流域水系模型，生成栅格水流流向，构建数字流域水系及空间拓扑关系；
On the basis of grid digital elevation data , the grid flow vector , digital basin and spatial topographical structure were generated for the upper catchment of the Hanzhong hydrological station on the upper Hanjiang River by use of the Digital Elevation Drainage Network Model for river basins .
