摘要
在阐述柴达木盆地耕地面临的荒漠化 (沙漠化和盐渍化 )问题及分析其自然和人文原因的基础上 ,提出了耕地荒漠化防治应该坚持的基本观点以及主要技术措施。认为耕地沙漠化防治的关键是处理好耕地与其生态环境之间的关系 ,以生物技术措施为主 ,最终建立完善的耕地防风固沙林草体系 ;耕地盐渍化防治的关键是处理好耕地与水资源之间的关系 ,以水利工程措施为主 ,利用区域治理模式降低土壤含盐量及地下水位。
Based on the present situation of farmland desertification and the analyzing of its natural and artificial factors, some basic ideas and main technical measures were put forward. The authors suggested that (1) more attention should be paid to the relationship between the farmland and its eco\|environment for the control of sand storm, lastly to establish perfected wind prevention and sand fixation system with biological technique as main measure; (2) for farmland salinization, more attention should be paid to the relationship between farmland and water resources, and by using the regional control model to decrease the soil salt content and lower the underground water table with water conservancy technique as main measure.
