以吉兰泰盐湖防风固沙林体系为对象,通过测定不同部位土壤理化性状,评估该防风固沙林体系防沙治沙效益,并可为干旱区植被恢复提供理论依据。结果表明:(1)吉兰泰盐湖防风固沙林带营建35年后,在林带拦截风蚀物质和植被改良共同作用下,原有流沙质地发生了明显改变。与流动沙垄相比,防护林带土壤细砂及粉粒含量显著增加,其增幅分别为30.55%,500.00%,粗砂含量与流动沙垄相比减少27.00%。(2)防护林带内土壤有机质、速效氮及全氮含量最高,分别是流动沙垄的252%,665%,1 466%;全磷各样地差异不明显,盐湖湖心土壤速效磷和速效钾含量最高,分别为流动沙垄的276%和202%;过渡带白刺灌丛样地土壤全钾含量最高,为流动沙垄的153%。总体上各养分含量与中砂、细砂、极细砂和粉粒呈现显著正相关关系。(3)土壤有机质、全氮和钾素能够综合反映防护林体系土壤质量改良效果,且防护林带土壤综合养分最高。在历经35年发展后,防护林带土壤速效氮、全氮和有机质含量分别增加204.20%,90.63%,94.11%,说明防风固沙林体系对土壤具有明显的改良作用。研究成果可为评价吉兰泰盐湖防风固沙林体系防护效益提供数据支撑。
Taking the Wind-breaking and Sand-fixing Forest System in Jilantai Salt Lake as the object
the physical and chemical properties of soil in different parts were investigated to evaluate the effect of the Wind-breaking and Sand-fixing Forest System
and provide a theoretical basis for vegetation restoration in arid areas. The results showed that:(1) After 35 years of construction of the Wind-breaking and Sand-fixing Forest System in Jilantai Salt Lake
the original quicksand texture changed significantly under the joint effect of intercepting wind erosion material and vegetation improvement. Compared with the moving dune
the contents of fine sand and powder in the targeted soil increased significantly (30.55% and 500.00%
respectively)
while the coarse sand contents decreased by 27.00%. (2) The soil organic matter
available nitrogen and total nitrogen contents in the shelterbelt were very high
which was 252%
665% and 1 466% of the moving dune. The difference of total phosphorus was not obvious. The contents of available phosphorus and available potassium in the lake were the highest
which were 276% and 202% of the moving dune
respectively. The highest total potassium content was observed in the transition zone with white thorn bushing
which was 153% of the moving dune. In general
the nutrient contents showed a positive correlation with medium sand
fine sand
very fine sand and powder. (3) Soil organic matter
total available nitrogen
and potassium could comprehensively reflect the soil quality improvement effect of the shelterbelt system
and the soil in the shelterbelt had the highest comprehensive soil nutrient contents. After 35 years of development
the soil available nitrogen
total nitrogen and organic matter in the shelterbelt increased by 204.20%
90.63% and 94.11%
respectively
indicating that the Wind-breaking and Sand-fixing Forest System had an obvious improvement effect on soil. These research results could provide data support for evaluating the protection benefits of the wind-fixing and sand-fixing forest system in Jilantai Salt Lake.
