This paper aims to figure out the influence of paving artificial nylon netted stabilization of sands on the function of the field blown sand hazard. We selected sediments and crusty nutrients characteristics of sand-fixing dune of south Tengger Desert,two kinds of natural flowing sand dune, protective forest as research objects. We studied sediments and crusty nutrients characteristics including components of sand grain, content of soil organic matter, available nitrogen, available phosphorus and available potassium at different position and depth. The results showed that the grain size characteristics of artificial sand dune and natural sand dune were different at different locations and depths. The function of sand barrier is obvious. There are three peaks in frequency curves of each geomorphologic position of artificial sand fixation dunes. σ_I becomes worse with the wind direction and better with the particle size becoming finer. S_k1 and K_g are significantly higher than other sand seas. Sediments in throughout the study area were slightly alkaline. The nutrient content of artificial sand-fixing dune was the highest. The content of available nitrogen and organic matter was the largest, while the content of available phosphorus and available potassium was slightly lower than that of artificial forest. The artificial sand barrier develops into dunes with vegetation on both windward and leeward slopes, and is covered with soil crust. Compared with the natural sand dunes, the distribution of grain-size fractions in artificial barrier area were more dispersive with higher content of organic matters. It can be seen that the sand barrier in the desert area has an important impact on the improvement of the regional soil environment and ecological environment.
