Loess Degradation and Improvement Measures

Abstract

Loess is a special soil type, widely distributed in our country. However, due to the influence of natural factors and human activities, loess has degraded, which has a negative impact on ecological environment, agricultural production and many other aspects. This paper elaborated the manifestations of loess degradation, such as soil erosion, fertility decline, soil structure destruction, etc., deeply analyzed the natural factors (including precipitation, wind power, terrain, etc.) and human factors (such as unreasonable land use, over-reclamation, overgrazing, etc.) leading to loess degradation, and proposed a series of improvement measures to address these problems. It includes engineering measures, biological measures and agricultural technology measures, aiming at providing theoretical basis and practical guidance for ecological protection and sustainable development of loess area.
