, 2009 围绕土壤结皮生物是否可以对夜间土壤吸附水输入产生响应展开研究。假定-1.5 MPa作为土壤水分有效性的临界值,通过观测降水后清晨和午后0~3 cm土壤含水量,分析土壤水分的有效性和空间异质性;并利用连续记录气象数据,建立表层土壤含水量与水汽压饱和差数量关系。结果表明:土壤吸附作用提高了土壤水分对土壤结皮生物的有效性,并延长了土壤结皮生物对降水脉冲的响应时段。在古尔班通古特沙漠东南部的不同部位,凝结吸附作用对沙面水分条件影响很大(特别是干旱季节),水分条件由好到坏依次为:沙垄西坡面、沙垄垄顶 ...

, 2009 针对制约滩涂土壤资源开发利用的障碍因素,以苏北滨海滩涂围垦区为研究区域,应用模糊综合评价方法对耕层土壤养分进行了分级与定量评价,获取了区域土壤肥力状况分布.结果表明,研究区域土壤磷素和钾素相对富余,有机质和氮素含量偏低,氮素亏缺较为严重,尤其是碱解氮.模糊综合评价表明研究区土壤养分分布在Ⅰ、Ⅱ、Ⅲ级,主要集中在Ⅰ、Ⅱ级,并没有Ⅳ级和Ⅴ级土壤;尽管总体上处于Ⅱ级水平,但可认为其养分仍处于极贫乏状态.研究区不同部位土壤养分分级存在明显差异性,养分分级较低的部位作物生长状况较差,土壤盐渍化程度较高 ...

Shuitu Baochi Xuebao, 2004 为了评价人工林下凋落物与土壤截留降水的能力,定位监测和分析了岷江上游23年生人工油松纯林下凋落物层和土壤层对65次降水事件的截留与分配过程。结果表明,65次林外降水总量为400.9 mm,其中208.726mm以穿透雨、33.388 mm以树干茎流进入林地,凋落物层、土壤层分别截留25.695,214.375 mm,截留率分别是6.41％,53.47％。但林外降水量<0.3 mm时,不产生林内降水,凋落物与土壤层不能截留降水。在0.3～10 mm降水范围内,土壤截留量随着降水增大呈增加趋势 ...
