In this study, as the research object the Ili Valley the Qapqal County Central Xinken agriculture demonstration area , the use of the basic theories and research methods of soil geography , physical and chemical indicators of system testing , including soil particle size through the acquisition of the new reclamation area soil samples , soil magnetic susceptibility , the experimental determination of soil salinity and soil nutrients , using a variety of data processing and analysis of spatial heterogeneity , correlation analysis , summarize the the demonstration zone soil surface Xinken and the physical and chemical properties of the soil profile characteristics . The results show : ( 1 ) the demonstration area Xinken land soil mostly powder ( sand ) soil powder (sand ) loam , spatial heterogeneity analysis showed that the main factors affecting the soil texture is the parent material, topography and other natural factors , the short-term artificial limited activities on soil texture . (2) multi- the demonstration area Xinken land surface soil in mild salinization of soil , soil salinity sulfate , in addition to the parent material , climate and other natural factors , the impact of human farming can not be ignored . ( 3) the demonstration area Xinken soil organic matter , nitrogen and phosphorus content of the whole amount of cohesion certain table , and after artificial cultivation of soil organic matter , the full amount of nitrogen and phosphorus content has greatly reduced , and the impact of land use on the soil surface larger soil calcium carbonate by human impact the profile distribution law is not obvious , uncultivated wasteland showing feature natural sierozem . (4 ) New Reclamation soil granularity the reclaimed farmlands , especially human tilling the land , soil texture coarsening trend arable clay content is lower than other land use types . (5) characteristics of soil magnetic susceptibility parameters under different land use patterns of the demonstration area , uncultivated wasteland can better reflect the study area natural gray calcareous clay into soil environmental conditions , and other types of land use soil magnetic susceptibility by artificial farming methods , crop type (C3, C4 crops) impact characteristics are different. (6) new reclamation area of soil salt content , and more serious, especially large area of abandoned land salinization salinization salinization problems to harsh to solve .
