Integrated Desert Control Pattern in Hunshandaka Sand Land and Its Benefit Evaluation——A Case Study of Duolun County

JIN Min; JIA Zhi-qing; LU Qi

The ecoenvironment in Duolun County located in the south-east part of Hunshandake Sand is very frangible,Many kinds of sand-desert control patterns such as vegetation recovery and tending technique on sand area,shrub afforestation with the protection membrane technique on the flowing dune,sand-fixation forest of multi-strips with narrow row pattern construction and management technique,and natural vegetation protection in grass-land and high-effect management technique of stockbreeding were implemented in this research and demonstration area.The typical pattern of sand-desert control and ecological farming sustainable development were built and remarkably comprehensive benefits were gained.After comprehensive control,vegetation cover-degree was increased by 33%,the rough degree of ground was increased by 183%～246%,soil drifting was reduced by over 90%,minuteness sand grain content in the air was fell off by 56%～80% above 1.5 m,the air humidity increased by 2.4%～9.1%,soil organic and nutritious substance increased by 37%～97%,fresh grass output increased from original 4 500 to 27 000 kg·hm-2,and the target of improving both the ecological benefit and economic benefit was realized in this research and demonstration area.
