新疆塔里木盆地东北缘绿洲不同土地利用类型土壤肥力评价
Soil Fertility Evaluation of Different Land Use Types in Northeastern Margin of Tarim Basin in Xinjiang
摘要
Abstract
To investigate the soil fertility status under different land use types in a typical arid oasis region,this study focused on five land use types in Kutie reclamation area in the northeastern margin of the Tarim Basin,including cropland,orchard,forestland,grassland and saline-alkali land.Soil indicators such as pH,total nitrogen(TN),total phosphorus(TP),total potassium(TK),available nitrogen(AN),available phosphorus(AP),available potassium(AK)and organic matter(OM)were measured.A fuzzy comprehensive evaluation method was employed to assess soil fertility comprehensively,aiming to provide scientific references for soil resource management and ecological restoration in the region.The results showed that the average soil pH in the study area was pH 8.16,with a variation coefficient(CV)of 0.037,indicating weak variability and predominantly alkaline or strongly alkaline soils.The levels of TP,TK,AP and AK were moderate to high,while OM,TN and AN were deficient.Soil fertility varied significantly among land use types,with cropland having the highest fertility,followed by orchard,while forestland,grassland and saline-alkali land had relatively lower fertility.The contents of OM,TN,AN,TP and AP in orchard and cropland soils were higher than those in forestland,grassland,and saline-alkali land.Overall,the soil fertility in the study area was relatively low,with available nitrogen and organic matter identified as the primary limiting factors.These findings provide a basis for improving soil management practices and promoting ecological restoration in arid oasis regions.关键词
