摘要: 隴東黃土塬區土質疏松、降雨時空分布不均,水土流失十分嚴重,溝頭不斷前進、塬面逐年萎縮,對當地農業和經濟發展造成了嚴重危害。為了給黃土塬區固溝保塬工程建設提供技術參考,對典型的黃土塬區——董志塬治理情況進行實地調研,系統總結了固溝保塬實施方案中的治理模式,通過遙感影像解譯評估了火巷溝固溝保塬工程建設的效果。目前董志塬西北塬區固溝保塬治理模式主要有簡單填埋型、排水+填埋型、排水+填埋+護坡型、排水+填埋+生態護坡型4種類型,其中排水+填埋+生態護坡型治理模式效果最為明顯。火巷溝2000年開始采取簡單填埋方式進行治理后,雖然短期效果明顯,但長期以來溝頭仍在不斷侵蝕前進,因此簡單填埋工程應配合徑流調控等措施,綜合防治溝道侵蝕、防止溝頭前進。建議厘清溝頭前進致災原因,針對主控因子“對癥下藥”;制定科學系統的防治體系,做到水不下塬、坡不滑塌、溝不擴展。

Abstract: The Loess Plateau in the East Gansu is characterized by loose soil and uneven spatial and temporal distribution of rainfall. The soil erosion is very serious with continuous advance of ditches and shrinkage of plateau surface year by year, which have caused serious harm to the local agriculture and economic development. In order to provide technical reference for the construction of Gully Consolidation and Highland Protection Project in the Loess Plateau area, a field investigation was conducted on the governance of Dongzhi plateau, a typical loess plateau area. The governance modes in the implementation scheme of Gully Consolidation and Highland Protection Project were systematically summarized and the effects of Huoxiang gully governance works were evaluated through remote sensing image interpretation. At present, there are four kinds of governance modes of gully consolidation and highland protection in the northwest plateau: simple landfill, drainage + landfill, drainage + landfill + slope protection, drainage + landfill + ecological slope protection, among which drainage + landfill + ecological slope protection has the most obvious effect. After the simple landfill method was adopted to treat the Huoxiang gully in 2000, although the shortterm effect is obvious, the gully head is still eroding in the long run. Therefore, the simple landfill project should coordinate with the runoff control and other measures to comprehensively prevent the erosion of the gully and prevent the gully head from advancing. It suggested that to clarify the causes of disasters, find out “the right medicine” for the main control factors and formulate a scientific and systematic control system, so as to achieve the goal of “water can be held by tableland, no slope collapse and no gully development”.
Key words: gully consolidation and highland protection; retrogressive erosion; engineering management mode; Loess Plateau; East Gansu
