Abstract

Abstract: Scotch Pine(Pinussylvestris var.mongolica)is distributed widely in Saihanba area of Hebei and there is a relatively large area and volume.On the basis of previous investigations and field trips,12 plots were set up and investigated according to different ages in the Qiancengban forest farm and by using typical sampling method.The soil was collected,treated,experimented and studied.The results showed that:(1)all kinds of soil nutrient contents varied with the depth of soil layer,and the content of soil nutrients decreased with the increase of soil depth,but the variation degree was different.(2)The correlation between the various factors in the soil was different.The correlation between pH and other nutrients were significant,namely it had little effect on other soil nutrient contents.Available phosphorus was significantly positive correlation only with total nitrogen,and with other factors did not reach significant level.Organic matter was significantly positive correlation with other soil nutrients in addition to the available phosphorus and pH value.(3)The soil nutrients from big to small order of Scotch Pine plantations was:10 years following>10-20 years>more than 40>30-40 years>20-30 years,namely soil nutrient with age increase showed a trend of decreased first and then increased.(4)The correlation between other soil nutrients and DBH had reached a significant level in addition to pH and available phosphorus.The regression equation of the correlation between the organic matter,total nitrogen,alkali solution nitrogen,total phosphorus,total potassium,available potassium,and the DBH were all polynomial functions.The range of R² was 0.6557~0.866(P<0.05).

Key words: Scotch Pine, Saihanba, soil nutrients, variation
