Abstract:
Taking the typical desert steppe in Yanchi of Ningxia as the research object，by selecting Achnatherum splendens and Artemisia desertorum community in enclosure and fence grazing areas，in order to research the change regulation of the water content，pH and the physicochemical properties in two communities of grassland fencing and grazing areas，the physicochemical properties of water content，pH and the change of soil.The results showed that the disturbance of grazing make a significant effect on soil water content and pH of desert steppe(P<0.05)，the soil water content of each soil layer in Artemisia desertorum community under the disturbance of grazing were 12.0%，12.3% and 16.6% higher than fencing area correspondingly，while as Achnatherum splendens community，the water content of each soil layer in fencing area were higher than that in grazing area；the change regulation of soil pH was consistent with the water content；in addition to the available phosphorus(AP),the content of other soil nutrient elements in enclosing area were higher than that in grazing area；furthermore，the soil organic carbon(SOC)，total nitrogen(TN)，available nitrogen(AN)，available phosphorus(AP) and available potassium(AK) had significant difference between enclosing and grazing area，while which made no obvious effect on total phosphorus (TP) and total potassium(TK)；the soil element of each soil layers in Achnatherum splendens community were higher than Artemisia desertorum community，while the relative increase was also large.
