摘要:
植被是江苏省黄河故道沙土区主要的水土保持措施，为定量评价不同植被措施所发挥的作用，通过自然降雨径流小区产流产沙观测试验，利用国内水力侵蚀抽样调查中植被措施因子计算方法，对沙土区几种常见的植被措施因子的取值和影响因素进行了研究。结果表明：（1）试验小区的年产流产沙量表现为：裸地 > 撂荒地 > 林草地 > 灌草地 > 混种草地 > 人工草皮，植被对产沙的影响更大，纯草本措施更具直接拦沙作用；（2）降雨侵蚀力和地表覆盖程度是影响植被措施因子的主要因素，降雨侵蚀力集中的月份其植被措施因子值占到了年值的64.52%～70.83%，随植被覆盖增加，降雨的影响明显减弱，植被的保土作用逐渐增强；（3）撂荒地、混种草、人工草皮、林草地和灌草地的植被措施因子年值（B）为0.499，0.184，0.048，0.266，0.224，说明后4种植被措施拥有良好的土壤保护能力，其抑制土壤侵蚀的效益指标均在70%以上，其中人工草皮达90%以上。
Abstract:
Vegetation is the main measure to control soil and water losses in sandy area of old Yellow River in Jiangsu Province. In order to evaluate the role of different vegetation measures quantitatively, we used the calculation method by sampling program of water erosion inventory in China to research the several common vegetation measure factors in sandy area through observation of runoff and sediment yield which caused by nature rainfall in runoff plots. The results showed that: (1) the runoff and sediment yield decreased in the order: bare land > abandoned land > arbor and herb land > shrub and herb land > hybrid grass > artificial grass, the influence of vegetation on soil erosion was greater, pure herbal measures had more direct effect on sediment reduction; (2) rainfall erosion power and surface coverage were the main influencing factors of vegetation measure factor, the factor value in months of the concentrated rainfall erosion power accounted for 64.52%～70.83% of the annual value, with the increase of vegetation coverage,the influence of rainfall decreased significantly, the function of plants on protecting soil increased gradually; (3) the annual B values of abandoned land, arbor and herb land, shrub and herb land, hybrid grass and artificial grass were 0.499, 0.184, 0.048, 0.266 and 0.224, respectively, which means that arbor and herb land, shrub and herb land, hybrid grass and artificial grass had powerful ability of soil conservation, and their performance indicators of soil erosion reduction were all above 70%, the indicator of artificial grass was above 90%.
