Because of rapid population growth， human development and utilization of land resources have been expanding， although the increased level of economic development， but due to the backward mode of production， irrational exploitation and utilization， make their own living environment is fragile， natural disasters occur Wetland is a prominent local environmental problems， mainly in: shrinking wetlands; sandstorm weather on wetland soil a serious impact on the natural environment; animal and plant decline， biodiversity is The special geographical location， it will directly undermine the deterioration of the quality of life of local residents， but also restricted the economic This paper studies the Sun Island wetland soil physical and chemical properties of the basic situation， the actual production of local activities and scientific research to provide scientific data， and for wetland ecological environment security and provide the basis for ecological restoration Articles by chemical element analysis， the watershed of the quantitative determination of soil physical and chemical properties， the selected indicators include the chemical properties of wetland soil total nitrogen， total phosphorus， organic matter determination， in the total nitrogen， total phosphorus and organic matter in determination There are many methods， the determination of total nitrogen in the method we used diffusion method; the determination of total phosphorus was determined using a Mo-Sb molten NaOH anti colorimetry; Determination of organic matter， we use an external heat source conditions， with a certain amount standard potassium dichromate - sulfuric acid solution to oxidize soil organic matter (carbon)， calculated by the amount of potassium consumed organic carbon content， organic matter content and then calculated Total nitrogen， phosphorus and organic matter in the determination of the results were the result of the second soil survey within the scope of total nitrogen content which meet two Wetland soil physical properties such as moisture content， bulk density， saturated water holding capacity， capillary water holding capacity， porosity measurement results are based on the land in the Northeast within the
