This article emphatically reviews the difference of soil chemical properties and biochemical activities between the rhizosphere and non-rhizosphere soil in different stages of Casuarina equisetifolia.It also reviews their dynamic patterns during Casuarina equisetifolia development.The result showed as follows:(1)In different stages of C.equisetifolia protection forest development

the pH value in rhizosphere soil was lower than that in non-rhizosphere soil and it shows the trend of declination in both rhizosphere soil and non-rhizosphere soil;The contents of organic matter

total N and hydrolytic N in rhizosphere soil was more than those in non-rhizosphere soil;Hydrolytic N shows the trend of declination in both rhizosphere soil and non-rhizosphere soil form half-mature stage to mature-stage;the content of total P and available P decreases from young stage to near-mature stage

and rehabilitate a little at mature stage;the content of total K and available K increases in rhizosphere soil.(2)In different stages of C.equisetifolia plantation development

the CEC

hydrolytic acidity and exchange Mg~(2 ) in rhizosphere soil were more than those in non-rhizosphere soil

except for exchange Ca~(2 ) in young C.equisetifolia protection forest;the CEC of soil arrive its max in half-mature stage.(3)As for the variation of the soil enzyme activity in different stages of C.equisetifolia protection forest

phosphataese

peroxidase and polyphenol oxidase were more active in rhizosphere soil than in non-rhizosphere soil;there was no obvious change on activity of urease;during stages of C.equisetifolia forest development

the active of phosphataese shows the trend of increase in both rhizosphere soil and non-rhizosphere soil

moreover

the difference between rhizosphere soil and non-rhizosphere soil were more obviously;the active of polyphenol oxidase in rhizosphere soil was more than that in other stages.
