中文摘要通过现场调查取样和室内理化试验,定量分析了岷江上游干旱河谷区阳坡土壤性质的空间变异特征,结合已有植被格局进行了区域土壤植被系统综合分析。研究结果表明:岷江上游干旱河谷区阳坡表层土壤粘粒含量极低,>0.25mm颗粒占45.2%;土壤微团聚体中表层<0.002mm的部分存在向下淀积或流失现象;pH值偏高,土壤N、P养分处于缺乏状态,且有效养分含量极低,土壤肥力水平低;土壤性质水平分异图显示:坡上部的疏林地土壤肥力高于其他土地利用地块,相对新植林地而言,靠近阴坡的疏林地植被恢复潜力更大。
英文摘要 The field investigation and analysis of physical and chemical properties of soil samples were conducted to elucidate the spatial characteristics of degraded soils on southfacing hillslope in the dry valley of Minjiang River,the mechanism of soil degradation was also discussed.The results showed that the clay contents of soils were low while coarser composition(>0.25 mm)accounted for 45.2% of total.The physical structure was unfriendly for vegetations.The micro-aggregates(<0.002 mm)in surface soil were illuviated or flushed away.Soil alkalinity was high as more than 8.2 while soil nutrients were deficient,especially for available nutrients of nitrogen and phosphorus.The spatial distribution illustrated that soil fertility under the sparse forest on upslope was higher than other land uses.Compared to the new afforested field,the sparse forest field near the northfacing hillslope can be restored more easily.
