The phosphorus forms and BAP vary with horizontal and vertical positions. The total phosphorus, inorganic phosphorus, BAY, and iron-phosphorus contents were high at a depth of 0~20 cm at the first sampling point, and then decreased at 20-40 cm of depth. This shows that the potential release capacity of P at 0-20 cm of depth is higher. The concentrations of total phosphorus and inorganic phosphorus decreased at 0~20 cm of depth and increased at 20~40 cm of depth at the second sampling point, but BAY and Fe-P increased along with the depth consistently. This shows that the deeper layer at the second sampling point had a higher potential release capacity of phosphorus.

To validate the above conclusion, a series of mixture tests were performed and different samples were made by mixing each of three kinds of nature silt and the nature clay with different mixture ratio. The liquid-plastic limits of all the samples, in which the clay particles content were between the nature silt and the nature clay, were attained using the combined test method. The results showed that the lowest clay particles content of the silt, when it was suitable with the combined test method, is 12% to 15% with little differences. If the point of 3～4mm depth of penetration of fall cone exist, and the loglog relationship between the depth of penetration of fall cone and the water content of all the points were clearly linear, it could be concluded that the clay particles content of the sample is over the lowest value when the combined test was suitable.

It will make the characters of ethnical and local culture eliminated. On the other hand, this tendency stimulates the arousal of the selfconsciousness of ethnical and local culture. The selfconsciousness comes from the recognition, that is the global culture be a combination of kinds of local culture, not a one kind of culture.
