%X Soil fertility and physical properties under different land use types in Minqin oasis of East Lake irrigation area were studied by field survey,lab experiment,statistical analysis and geostatistics analysis methods.The results showed that land use types influenced obviously on soil moisture,nutrients and salinity,but influenced little on soil pH.The highest variation coefficient of soil moisture,about 50%,occurred in the returning farmland to forest,while the smallest one occurred in the farmland.Soil moist...
