华亭县土石山区水土流失控制技术与效益研究

Research of Huating County Earth-rock Mountain Region Water and Soil Loss Control Techniques and Benefits

华亭县土石山区属黄河流域多沙粗沙区,该区生态环境脆弱,水土流失严重,在该区开展小流域水土流失控制技术与效益研究,对促进黄土高原小流域生态建设有重要意义。本文采用统计分析的方法,通过对七条典型小流域的泥沙来源、土壤侵蚀量和治理措施分布的时空顺序的分析研究,得出结论:不同治理模式,在治理程度相近的情况下,水保效益差异显著。这为水土流失治理指出了方向。

Huating County Earth-rock Mountain Region belongs to coarse sand area in Yellow River Drainage Basin, which has weak ecological environment and serious soil erosion. The small watershed water and soil loss control techniques and effectiveness can be studied in the district, which has important significance to promote the ecological construction of small watershed. Statistical analysis method is adopted in the paper. The time and space order of sediment sources, soil erosion and control measure distribution in seven typical watersheds are analyzed and studied. The following conclusion can be obtained： water conservation benefits are significantly different due to different governance modes under the condition of similar governance levels, thereby ~uiding water and soil loss ~overnance.
