| Abstract: |
| With Hetian Oasis shelter-forest construction as the background, sampling investigation was conducted in 11 plots according to different structures of shelter-forest configuration types. Conventional analysis
was used to determine soil nutrients and soil salinity, including the pH value, conductivity, total soil water-soluble salts. The results show that soil relative water content of shelter-forest with different planting model is different. Multi-level planting shelterbelts can change soil salinity, reducing soluble salt accumulation in soil. The spatial variation of soil nutrients of shelter-fo
rest in different structure is obvious. Different planting patterns have a significant positive effect on the accumulation of soil nutrients and improve soil fertility, increasing the species within shelter-forest. In conclusion, suggestions are pointed out on planting patterns. |
