[Response of Soil Microbial Diversity to Long-term Enclosure in Degraded Patches of Alpine Meadow in the Source Zone of the Yellow River].

The soil pH, water content, nutrients, and microbial community composition and diversity among one-year term (E1), short-term (E4), and long-term (E10) enclosures were analyzed for understanding the response of soil bacterial and fungal communities to long-term enclosure in degraded patches of alpine meadow in the source zone of the Yellow River, through determining the soil physicochemical properties and microbial diversity using high-throughput sequencing technology. The results showed that the E1 enclosure significantly decreased soil pH, whereas long-term and short-term enclosures increased soil pH. The long-term enclosure could significantly increase soil water content and total nitrogen content, and the short-term enclosure could significantly increase available phosphorus content.
