摘要/Abstract

摘要： 探究两性离子型PVAc共聚乳液用于高盐沙地治理的技术依据，从固沙性能和生态效应两方面为切入点，详细研究了两性离子型PVAc共聚乳液用于高盐沙地生态固沙的综合效果。研究结果表明，两性离子型PVAc共聚物不但具有良好的耐盐性能，而且将其用于高盐沙地固沙，在施用浓度为2.0%时，两性离子型PVAc共聚乳液的固沙强度达到0.46 MPa，已满足沙漠环境中抗风蚀性能的要求。另外，相比于非两性离子型PVAc共聚乳液而言，两性离子型PVAc共聚乳液可明显提高沙土的保水性能，增加水分的利用率，从而促进沙土微生物的生长。这些实验结果表明，两性离子型PVAc共聚乳液可作为一种新型生态固沙剂应用于高盐沙地的生态治理。

Abstract: In order to obtain the technical basis of the amphoteric PVAc copolymer emulsion used in ecological sand-fixing of salty desert, a detailed investigation was conducted for illuminating both the sand-fixing properties and ecological effect of the amphoteric PVAc copolymer emulsion. The experimental results showed that the amphoteric PVAc copolymer not only had excellent salt resistance, but also the sand-fixing strength of the amphoteric PVAc copolymer emulsion reached 0.46 MPa when the used concentration was 2% for sand-fixation in high salt-affected sandy land, which had met the requirements of wind erosion resistance in desert environment. In addition, compared with non-amphoteric PVAc copolymer emulsion, the amphoteric PVAc copolymer emulsion could significantly improve the water-retention property and increase the utilization rate of water, thus it could promote the growth of sandy soil microorganisms. These experimental results showed that the amphoteric PVAc copolymer emulsion could be used as a novel ecological sand-fixing material for the ecological management of salty desert.
