Assessing nonpoint-source nitrogen loading and nitrogen fixation in lakes using δ15N and nutrient stoichiometry
Assessing nonpoint-source nitrogen loading nitrogen fixation lakes using δ15N nutrient stoichiometry
2014/4/3
Runoff from human-dominated watersheds has greatly altered nitrogen (N) and phosphorus (P) cycling in lakes. Nutrients from human sources are distinct from those from undisturbed ecosystems in several...
Study of Mechanism of the W-OH Sand Fixation
W-OH Sand Fixation Adhesive Force Porosity Solidifying Time Wind Tunnel Test
2013/3/11
A novel hydrophilic polyurethane (abbreviated as W-OH) was developed and applied as a sustainable sand-fixing material. This paper on the chemical sand fixation mechanism of W-OH discusses the adhesiv...

液化玉米秸秆基固沙剂控制土壤风蚀试验（Experiment on Sandy Fixation Material Based on Liquefied Corn Stover to Decrease Wind Erosion）
玉米秸秆 液化 聚氨酯 土壤风蚀 固沙剂
2010/5/5
以室内风洞试验机为主要设备，研究了液化玉米秸秆及液化玉米秸秆基聚氨酯作为固沙剂对筑渣土的保护效应。研究结果表明，二者均能粘结土样表面的大小颗粒形成保护层，提高建筑渣土的抗风蚀性；当液化玉米秸秆的喷施量较低时，随着风速的提高，对土壤的保护作用逐渐消失，土壤的侵蚀度迅速增加；液化玉米秸秆基聚氨酯作为固沙剂的效果要明显优于液化玉米秸秆，当其喷施量为120.37g/m2时，起沙风速超过20m/s，当固沙效...
