研究目的:提出山地丘陵地区坡式梯田土地整治工程的快速测算方法.研究方法:根据山地丘陵区土地整治规划设计基础图件的特点,结合GIS软件的坡度分区等统计功能,应用数字高程模型(DEM)原理,根据推导的坡式梯田土地平整工程量公式,提出山地丘陵区土地整治项目坡式梯田土地整治工程量的快速简捷测算方法和流程,并以湖北省阳新县三溪镇低丘岗地改造项目为案例验证该方法的可行性.研究结果:运用GIS进行坡式梯田土地整治工程量的测算具有可行性,只需运用GIS统计获得整治区不同坡度分区的面积,就可依据坡式梯田断面设计要素(田坎高度、田坎坡度和降坡后地面坡度)快速测算不同坡度范围的土地平整量.研究结论:该方法具有简便、快捷的特点,具有较强的实用性,可大大提高土地整治工程规划设计的效率.

The purpose of the paper is to explore a new approach to estimate the earthwork of sloped terraces in hilly regions. The approach was developed by applying digital elevation model(DEM)theory and statistical function of the slope with GIS software according to the derived formula. A land remediation project was chosen as an empirical research example to use the proposed approach in Yangxin County, Hubei Province. Study found that the use of GIS for earthwork estimation of sloped terrace is feasible, the earthwork of different slope range could be estimated quickly according to sloped terrace section(i.e., ridge height, ridge slope and the field surface slope after down slope) after getting the area of different slope range using GIS. The paper concludes that the proposed approach is simple and fast with strong practical characteristics. It provided a new way to estimate the earthwork of sloped terrace in hilly area. The approach can improve the efficiency of project planning and design.
