退化苏打盐渍草地土壤特性研究

STUDIES ON THE CHARACTERISTICS OF THE SOILS OF THE DEGRADED SODA SALINED GRASSLAND

应用遥感技术、野外调查、室内分析和数理统计方法,对退化苏打盐渍草地土壤特性的研究表明,受人为活动的强烈影响。盐渍草地可利用面积日趋减少,生产力不断下降,最终导致土壤普遍退化,但与植被退化相比,土壤性质恶化具有一定的时间滞后性,这就为区域草地及土壤生态建设提供了重要的科学依据。

This paper is a study of the soils characteristics of the degraded soda salined grassland by making use of the techniques of remote sensing, field investigation and the methods of indoor analysis and statistics analysis. The results show that because of the great influence of artificial activities the utilization area of the salined grassland has been declining and the productive forces weakening,which has finally resulted in the general degradation of soils. But compared With the plant degradation,the soil deterioration is somewhat slower,And that provides scientific basis for the reconstruction of the regional grassland and soil ecology.
