Ecological ditch-and-source-preserving restoration method for slopes in gully regions of eastern-Gansu Loess Plateau
The invention relates to an ecological ditch-and-source-preserving restoration method for slopes in gully regions of eastern-Gansu Loess Plateau. The method is used for carrying out analysis of the landform, erosion degree and groundwater distribution of the slopes in combination with a topographic map in order to match corresponding slope types. The slope types include (1) large slopes with large cutting and filling areas; (2) large slopes that are in a development period and with surrounding conditions not allowing large-area cutting and filling works; (3) sections with small landslides with a relatively great sliding risk, good overall stability and with landslides and less-stable slope local soil bodies having wedge sliding hazards; (4) small slopes with stretch-draw cracks at back edges; (5) small slopes or unstable blocks not allowing cutting and filling works; and (6) sections having construction and structures needing to be protected. According to the invention, on the basis of maximized protection of the original topography, landform and ecological substrate of the Loess Plateau, point-to-point and precise restoration of the gully regions of different topography and landforms in eastern-Gansu Loess Plateau is realized.
本发明涉及一种陇东黄土高原沟壑区固沟保塬边坡生态修复方法，结合地形图对边坡进行边坡地貌、侵蚀程度、以及地下水分布分析，以匹配对应的边坡类型，边坡类型包括：(1)具有大面积削方和填方区域的大型边坡；(2)正在发育期间且周边条件不允许采用大面积削方和填方工程的大型边坡；(3)具有较大滑塌风险的小型滑坡体、整体稳定性尚好，滑坡体及欠稳定坎坡局部土体存在楔形滑动危险的地段；(4)边坡后缘具有张拉裂隙的小型边坡；(5)不允许削、填方的小型边坡或不稳定块体；(6)有需要保护的建、构筑物地段。本发明在最大限度保护原有的黄土高原地形、地貌及生态基底的基础上，可实现针对不同的地形、地貌形态的陇东黄土高原沟壑区进行点对点精准修复。
