Abstract:: Soil samples in different positions of slope in the upper, middle and down stream of Binzhou river basin were collected to analyze the spatial distribution of soil alkaline phosphatase and soil organic matter, as well as effects of soil erosion on them. The results showed that soil alkaline phosphatase and soil organic matter ranked as down stream > middle stream > upper stream at watershed scale. Soil alkaline phosphatase and soil organic matter in the different slope positions followed the order of top slope < the middle slope < down slope, slope position played more important role in the distribution of soil organic matter than that in soil alkaline phosphatase. There was a significant positive correlation between soil alkaline phosphatase and soil organic matter. The spatial distribution of soil alkaline phosphatase activity and soil organic matter was corresponding to soil erosion, suggesting that soil erosion was the key factor governing spatial distribution of soil alkaline phosphatase and soil organic matter in Binzhou river basin.
