摘要: 关中唐十八帝陵是古代中国留给后代宝贵的历史文化遗产,千年以来帝陵遗址区水土流失现象加剧,破坏了帝陵景观。为了保护文化遗产,本文以某唐帝陵为对象,使用卫星和无人机影像产品,估算53年来司马道冲沟的发育速率,建立了帝陵遗址区的水土流失体积-面积关系模型。结果表明:①遗址区受益于还林换草工程,坡耕地减少,草地林地增加。司马道下游林区NDVI指数达0.8,生态环境明显好转,水土流失等级转为轻度。②渭北旱塬地区,发育为卵状冲沟与其垂直面的切沟,周长与面积有良好的拟合关系。③唐帝陵遗址区的沟道发育模型,面积和体积之间有良好的幂函关系,即y=0.040 5 x1.493 6,决定系数R2=0.82,53年来的切沟年发育为0.36 m/a。可将上述模型作为渭北旱塬地区沟道发育模型。④遗址区水土流失和土壤沉积体积比率为38.5∶1,产生的侵蚀和土壤沉积面积比率为11.5∶1。

Abstract: Guanzhong Eighteenth Tang Dynasty Imperial Mausoleum is a valuable historical and cultural heritage in ancient China.In the past thousand years, soil and water loss existed in different degrees in the Imperial Mausoleum site area, which destroyed the landscape of the imperial Mausoleum.In order to protect cultural heritage, using satellitie and UAV imaging products to estimate the development rate of shallow gully erosion in the past 53 years.The volume-area relationship model and soil erosion level are established.The results showed that: ①The site area benefite from the project of returning forest and grass, the land use slope farmland continued to decrease, and the grassland and forest land increase.The NDVI index of the forest area in the lower reaches of Sima road reaches 0.8, and the ecological environment of the site area improve significantly.The level of water loss will change from the severe one in 1968 to the mild one in 2021.②In Beishan area of Guanzhong, it develops into egg shape gully and its vertical cut, with a good fitting relationship between perimeter and area.③The gully development model of the site area of Tang Emperor's Mausoleum in Guanzhong Beishan area, on the southern edge of the Loess Plateau, has a good power function relationship between area and volume, y=0.040 5x+1.493 6, and the determination coefficient is R2=0.82。 The annual development of gully cutting in the past 53 years is 0.36 m/a.The above model can be used as the gully development model in the southern edge of the Loess Plateau and the northern mountain area of Guanzhong.④ In the whole site area and its surrounding areas, the ratio of water and soil loss and soil sediment volume is 38.5∶1.The area ratio of erosion and soil deposition is 11.5∶1.

Key words: shallow gully erosion, loess hilly area, GIS, protection of Tang Imperial Mausoleum Sites
