摘要:
针对沿海新垦区盐土盐份高、土壤结构差、有机质含量少等特点,对沿海新围垦区沟渠边坡高含盐土壤侵蚀开展试验分析,研究土壤侵蚀变化规律,利用实测数据验证模型,分析WEPP 模型适用性。通过野外径流小区试验分析及模拟结果说明在自然降雨条件下,沿海新垦区径流小区盐碱土侵蚀主要影响因素是雨量、降雨强度,且均为正相关显著关系。WEPP 模型模拟出侵蚀量的模型有效性系数平均为0.543,计算结果表明WEPP 能较好模拟沿海新垦区沟渠边坡侵蚀情况,在特殊的自然条件下尚需修正。
Abstract:
According to the characteristics of high salt content, poor soil structure and low organic matter content of salt soil in the new coastal reclamation area, experimental analysis was conducted on high-salted soil erosion in the trench slope of the new coastal reclamation area to study the change law of soil erosion.The model was validated using measured data to analyze the suitability of the WEPP model.The experimental analysis and simulation results of field runoff plot indicated that under natural rainfall conditions, the main influencing factors of saline-alkali soil erosion in runoff area of new coastal reclamation area were rainfall and rainfall intensity, and both were positively correlated and significantly related.The WEPP model simulated the erosion rate, and the average effective coefficient of the model was 0.543.The results showed that WEPP could better simulate the erosion of the gullies in the new coastal reclamation area, and it need to be corrected under special natural conditions.
