Land restoration in the gully regions of China's Loess Plateau has significantly altered soil conditions and farming practices, yet its impact on soil microbes remains unclear. This study applied metagenomic sequencing and correlation analysis to examine microbial community shifts and key genes involved in carbon, nitrogen, and phosphorus cycling. Results show increased biodiversity and microbial activity, especially downstream, enhancing carbon metabolism and ecosystem resilience. Phosphorus activation improved, with related gene abundance rising by 27.45 %-52.57 %, facilitating phosphorus availability. Nitrogen cycling showed enhanced nitrification and nitrogen fixation, with reduced denitrification, promoting nitrogen retention. Soil organic carbon, total nitrogen, ammonium nitrogen, and available phosphorus (AP), particularly AP, strongly influenced microbial dynamics. These findings highlight the positive role of land restoration in improving soil health and nutrient cycling, supporting sustainable agriculture.
