- [目的]探究西柳沟流域土壤风蚀与景观格局的响应关系,为该地区生态修复提供科学依据。[方法]基于气象、土壤、植被覆盖、土地利用等数据,采用修正土壤风蚀模型(RWEQ),计算分析了2005—2020年流域内土壤风蚀量及其影响因子,阐明了流域内土地利用变化特征。[结果](1)2005—2020年,西柳沟流域土壤风蚀量呈先增长后下降趋势,2005年、2010年、2015年、2020年的平均风蚀量分别为36.9,39.4,45.3,39.4 t/(hm2·a),且在空间上总体呈现“北强、南弱”趋势。(2)气象因子值在2015年前后变化显著; 空间上,其值在流域北部低南部高,中部变化较大。(3)流域主要以裸地和低植被覆盖度为主,占总面积79%以上; 土地利用主要以草地为主,占总面积82%以上,草地面积总体呈增加趋势,整体较为破碎,斑块形状向复杂化发展。自2010年起,草地中度、强烈风蚀占比均超过85%。[结论]西柳沟流域风蚀量在长期生态保护修复下略有降低,但在气候变化和人类活动影响下,未来科学实施生态修复依旧是西柳沟流域的重要研究方向。
- Abstract:
- [Objective]The aims of this study are to investigate the response relationship between soil wind erosion and landscape pattern in Xiliugou watershed, and to provide scientific basis for ecological restoration in this area. [Methods]Based on meteorological, soil, vegetation cover, land use and remote sensing data, the corrected soil wind erosion model(RWEQ)was used to calculate and analyze the soil wind erosion and its influencing factors in the watershed from 2005 to 2020, and the land use change characteristics in the watershed were clarified. [Results](1)From 2005 to 2020, the soil wind erosion in Xiliugou showed an increasing trend and then a decreasing trend. The average wind erosion rates in 2005, 2010, 2015 and 2020 were 36.9, 39.4, 45.3 and 39.4 t/(hm2·a), respectively. And the overall spatial trend of erosion rate demonstrated the strong level in the north and the weak level in the south.(2)The values of meteorological factors changed significantly before and after 2015. Spatially, its value was lower in the north and higher in the south, but it varied greatly in the middle part.(3)The basin was dominated by bare land and low vegetation coverage, accounting for more than 79% of the total area. The land use was mainly grassland, accounting for more than 82% of the total area. The overall area of grassland was increasing, the overall was relatively broken, and the shape of patches was becoming complicated. Since 2010, the proportion of moderate and strong wind erosion in grassland had exceeded 85%. [Conclusion]The wind erosion in Xiliugou watershed has slightly decreased under long-term ecological protection and restoration, but in the face of climate change and human activities, scientifically implementing ecological restoration will still be an important research direction for the Xiliugou watershed in the future.
