黄河三角洲盐碱地道路防护林对土壤的改良效应

Shuitu Baochi Xuebao, 2011
为探讨黄河三角洲盐碱地不同道路防护林对土壤的改良效应,选取白蜡(Fraxinus chinensis)+毛白杨(Populus tomentosa Carr)混交林、旱柳(Salix matsudana Koidz)林、柽柳(Tamarix chinensis Lour)林、白蜡(Fraxinus chinensis)林4种盐碱地道路防护林类型,并以裸地为对照,对其土壤容重和孔隙度、pH值和含盐量、土壤养分及C、N、S含量特征进行对比研究。结果表明:①与裸地相比,不同道路防护林具有降低土壤容重 ...

基于RS和GIS的黄河三角洲土地利用变化及生态安全研究——以东营市为例

Shuitu Baochi Xuebao, 2008
基于RS和G IS技术,以东营市为例,研究黄河三角洲的土地利用变化及其结构特征,确定综合土地生态风险指数,然后通过系统采样、变异函数分析及空间插值对土地生态风险指数进行变量空间化,生成1996和2005年土地生态风险演变规律分布图。研究结果表明:近10年来东营市土地利用变化剧烈,居民工矿用地大幅增加,次生盐碱地所占比重较大,油田生产建设和生态环境保护矛盾比较突出;近10年来,生态风险重心已经由南部的广饶地区转移到中部的东营地区,生态风险有进一步恶化的趋势,区域内土地生态风险分布极其不平衡 ...

水炭运筹对黄河三角洲钠质盐土降盐效果

Shuitu Baochi Xuebao
目的为明确生物炭施加量和灌水量对黄河三角洲地区钠质盐土的降盐效果。方法采用二因子五水平正交旋转组合设计，通过土柱试验，模拟灌水量（以土壤饱和水分体积分数（θs）的1.00、1.07、1.25、1.43、1.50倍）和生物炭施加量（以0~20 cm土层土壤质量（Sw）的1.00%、1.59%、3.00%、4.41%、5.00%）对钠质盐土土壤质量含水率、电导率、pH及离子质量分数的影响，并通过层次分析法和多元回归方程综合确定最优水炭组合配比。结果1）4.41%Sw与1 ...
