摘要
以淄川水土保持生态修复区峨庄流域为研究区域,综合运用"3S"技术和水土保持相关理论与方法,对1990年和2005年峨庄流域土壤侵蚀格局与动态进行了系统研究。结果表明:15年来峨庄流域的土壤侵蚀综合防治效益日趋显著;流域土壤侵蚀类型为水力侵蚀,土壤侵蚀强度以轻度侵蚀为主,局部区域存在中度和强度侵蚀;土地利用、植被盖度、坡度等环境因子对流域土壤侵蚀影响密切。研究成果可为优化水土保持措施提供决策依据和技术支撑。
This paper takes E'zhuang watershed located in Zichuan water and soil conservation ecological restoration as the study area,uses 3S technique and related soil and water conservation theory and methods comprehensively,studies 1990s' and 2005s' soil erosion and dynamic pattern of E'zhuang watershed.The results indicate:Integrated Control benefits of soil erosion increase significantly day by day;The type of soil erosion is water erosion and the mild erosion is the main soil erosion intensity type,moderate and serious erosion exists only in some areas;The relationship between soil erosion and the way of land utilization,vegetation coverage,the slope is close.The research results can provide technical support and determine the reasonable water and soil conservation measures.
