摘 要:古梯田的形成与发展充分证实了坡改梯工程是山区水土保持的一项重要措施.通过无人机遥感技术获得分辨率为0.1~0.5m的遥感影像,利用ArcGIS等地理信息系统软件进行数据处理,结合景观软件Fragstats3.3计算特征指标,对贵州省黄平县4个古梯田景观格局进行研究.结果显示:研究区梯田景观和林地景观约占整个景观的80%,其中梯田约占30%,林地约占50%;单块田块平均面积多集中在100~200m2、高度0.7 ~1.7m、宽度0.5 ~0.6m;所在坡度为5~25°的梯田最多,约占总田块数的70%.运用古梯田中蕴含的水土保持思想,为坡改梯工程以及坡耕地水土流失治理提供借鉴.The formation and development of the ancient terraced fields fully confirmed the terrance mountain is one of the important measures of soil and water conservation. In order to study four ancient terraced fields landscape pattern in Huang ping County, Guizhou Province, we used geographic information system software such as ArcGIS for processing data, combined with the feature of landscape Fragstats3.3 to calculate software metrics by using Uav remote sensing technology for remote sensing image with resolution of 0.1 -0.5m. The research showed Terraced landscape and forest landscape in the study area accounts for about 80% of the whole landscape, terrace accounted for about 30% , forest land accounts for about 50% ; the area of single block field area mostly are 100 -200m2, their height is 0.7 - 1.7 m and width is 0.5 -0.6m ; where the slope is 5 - 25 ° terraces, most accounts for about 70% of the total number of plots in. According to the results. We can use science and technology in soil and water conservation of ancient terraced fields to provide reference for terrance engineering and farmland soil and water loss.
