Protective Effect of Shelterbelt on Strip Fields in Southwest Margin of Taklimakan Desert
Journal Title: Bulletin of Soil and Water Conservation - Year 2023, Vol 43, Issue 3
Abstract
[Objectives] The windbreak efficiency of shelterbelts with different permeability on strip fields at the edge of the oasis in the Taklamakan Desert was analyzed in order to provide theoretical guidance for sustainable development of local grid strip fields. [Methods] The peri-urban shelter forest in the Qiaqikumu area of Yecheng County, Xingjiang Wei Autonomous Region on the southern edge of the Taklamakan Desert was selected as the research location. Field observations were made to quantify the windbreak effect for shelterbelts with different structures on the edge of the Taklamakan Desert oasis. [Results] ① The strip field within 10—15 m of the leeward side of the shelterbelts in the Qiaqikumu area of Yecheng County experienced the best windbreak effect. Crops with poor ability to withstand wind damage can be planted in this strip field. ② In general, the windbreak effect provided by shelterbelts was highest for plants with a height of 1.5 m and lowest for plants with a height of 2 m. Therefore, planting crops with a plant height of less than 1.5 m in the shelterbelts can effectively minimize losses caused by wind damage in this study area. ③ The sand fixation efficiency of the open-structure shelterbelt was the greatest, followed by the ventilated-structure shelterbelt. The sand fixation efficiency of the compact-structure shelterbelt was the worst. The order of sand fixation efficiency for the three kinds of structural shelterbelts followed the order of 58.39%>57.99%>36.29%, respectively. [Conclusion] In order to increase the sand-fixation efficiency of shelterbelts, open-structure shelterbelts should be recommended. This shelterbelt type can achieve the best windbreak effect. Strip fields around open-structure shelterbelts can be planted with crops having weak sand resistance.
