In the urbanization process,the change in land utilization is very swift.In order to investigate the effects of land utilization change and human activity on the spatial distribution of soil nutrient,we took the western suburb of Hangzhou as a research area.Sloping lands with three utilization ways of mixed forest,bamboo forest and cultivated sloping land were selected.In the horizontal direction,the whole sloping land was divided into four slope segments of the top,upper,lower and bottom,each of which has three samplings taken.In vertical direction,three depths at each sampling point were determined,i.e.,5,10 and 15 cm.Totally,36 samples were taken.The contents of N,P and K for each sample were measured,and 108 data were obtained for analysis.According to the measurements and systematic analysis,some conclusions have been gained.The absolute contents of N,P and K are the highest and the change in spatial distribution is the most obvious at the depth of 5 cm on sloping land.However,the most obvious change is observed at the depth of 10 cm on sloping land with bamboo forest.The change in the spatial distribution of the contents of N,P and K is very distinct.From the top of sloping lands to the bottom,the contents of N,P and K show a decreasing trend,and the intensity of decreasing trend is the greatest on sloping land.The main reasons for soil nutrient changes are the different ways of land utilization and the intensity and frequency of human activities.Loss of soil nutrient on sloping land is coincident with soil and water loss and water confluence.
