“…Furthermore, our results indicate that the Shannon and Chao1 indices were significantly higher in HF soils compared to MF and LF soils. These findings suggest that enhancing soil fertility can provide a more nutrient-rich environment for microbes, leading to increased diversity ( Jin et al, 2014 ; Hartmann and Six, 2023 ). The difference in beta diversity was mainly between HF and LF, which indicated that microbial community was significantly different between HF and LF.…”

Soil bacterial communities are intricately linked to ecosystem functioning, and understanding how communities assemble in response to environmental change is ecologically significant. Little is known about the assembly processes of bacteria communities across agro-ecosystems, particularly with regard to their environmental adaptation. To gain further insights into the microbial community characteristics of agro-ecosystems soil in the Panxi area of Sichuan Province and explore the key environmental factors driving the assembly process of the microbial community, this study conducted field sampling in major farmland areas of Panxi area and used Illumina MiSeq high-throughput sequencing technology to conduct bacterial sequencing. Soil organic matter (SOM), alkali-hydrolyzed nitrogen (AN), available phosphorus (AP), available potassium (AK) and other environmental factors were determined. The membership function method and principal component analysis method were used to evaluate the fertility of the soil. The results revealed minimal differences in alpha diversity index among samples with different comprehensive fertility indices, while NMDS analysis showed that community differences between species were mainly reflected in high fertility and low fertility (R: 0.068, p: 0.011). Proteobacteria, Acidobacteria and Actinobacteria were the main types of microbial communities, accounting for more than 60% of the relative abundance. Proteobacteria accounted for a higher proportion in the high fertility samples, while Acidobacteria and Actinobacteria accounted for a higher proportion in the middle and low fertility samples. Both the neutral theoretical model and zero model analysis showed that the microbial communities in tobacco-planting soil with different comprehensive fertility indices presented a random assembly process. With the increase in environmental distance difference, the diversity of the microbial community in medium and low-fertility soil also increased, but there was no significant change in high-fertility soil. Redundancy analysis showed that pH and SOM were the key factors affecting microbial community composition. The results of this study can provide a theoretical reference for the study of environmental factors and microbial communities in tobacco-growing soil.

The longest artificial highway shelterbelt flowing across the Taklamakan desert was conducted in 2005. To ensure the sustainable development of the highway and shelterbelts, scholars have carried out a large number of studies on the shelterbelt since 1991. This review is based on a 30-year monitoring program from 1991 to 2021. We find that, with the increase of shelterbelt age, some ecological and economic benefits gradually appear, such as saving transportation cost, promoting economic development in Southern Xinjiang, improving the sandy soil and microenvironment, and increasing the biodiversity. In the meanwhile, some adverse phenomena also exist, such as high maintenance costs, decrease in water tables because of irrigation, threats of the protected species, pollution from pumping oil wells, and the potential damage from highway burying as sand dunes move forward. In view of these problems, some suggestions are as follows. First, the science-policy sections of both the UNFCCC and the UNCCD should pay special attention to providing research-based guidance for the international cooperation and coordination. Second, China government should provide the necessary funding to establish the 27th China desert observation and research station to ensure long-term monitoring and slow down the pace of construction on the desert highway to allow time to develop strategies that minimize the impact on wild animals. Third, it is necessary to apply solar photovoltaic power in well irrigation and sand industry development. Fourth, the sand-blocking belt of 10 m width and 10 m away from the outside of the upwind shelterbelt can be laid every five years in view of sand-buried roads. In short, the inter-agency collaboration and coordination are both essential to ensuring the success of sustainable development and management of the Taklamakan Desert man-made ecosystem.
