华亭县土石山区水土流失控制技术与效益研究

Huating County in mountainous area of soil erosion control technology 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。该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,得出在治理模式不同,在治理程度相近的情况下,其水保效益差异显著。建立良好的生态环境是经济社会发展的基础,水土保持是土石山区生态环境建设和新农村建设的基础。

Huating County in mountainous area Coarse Sand Area in Yellow River basin,fragile ecological environment in the region,serious soil erosion,small watershed soil erosion control technology and benefits of research carried out in the area,promote small watershed in the Loess Plateau Ecological Construction.In this paper,using the method of statistical analysis,analysis of the seven typical small watershed sediment sources,the amount of soil erosion and governance measures temporal and spatial order,the governance model,in the case of a similar level of governance,water ensure effective significant difference.Good ecological environment is the basis of economic and social development,soil and water conservation ecological environment construction in mountainous area and new rural construction.
