“…The global area of naturally regenerating forests is about 3.737 billion hectares, which decreased at a declining rate of loss since 1990 (FAO, 2020). Rapid social and economic development and the expansion of agribusiness activities have resulted in ecosystem degradation and widespread conversion of primary and secondary forests into agricultural fields and tree plantations (Drescher et al, 2016;Tateishi et al, 2021). Generally, primary forests (including secondary forests) are naturally occurring forests that have not been cultivated or less disturbed by humans, and in primary forests, there are companion tree species, young trees and other ground covers in addition to dominant species.…”

IntroductionLand-use changes significantly impact soil properties in forests, which is an area of concern. Therefore, the effects of changing forest types on soil microbial communities and their functions in northern subtropical forest regions need to be further researched.MethodsWe used 16S rDNA sequencing and Functional Annotation of Prokaryotic Taxa (FAPROTAX) to assess the variation of soil bacterial communities and potential functions related to carbon (C) and nitrogen (N) cycling in two soil layers (0–10 and 10–30 cm) after the conversion of the secondary masson pine (Pinus massoniana, PM) forest to plantations of slash pine (Pinus elliottii, PE) and Chinese fir (Cunninghamia lanceolata, CL) located in Jingde County, Anhui Province, China.ResultsThe study found that converting coniferous secondary forests to coniferous plantations resulted in a notable increase in soil pH and a decrease in nitrate nitrogen and organic carbon contents. Additionally, soil microbial diversity increased significantly, and microbial community structure changed, particularly in the topsoil. These changes might affect the C- and N-cycling mediated by soil bacteria. The analysis revealed a significant decrease in the abundance of functional groups associated with C-cycling and a significant increase in the abundance of functional groups associated with N-cycling, particularly those associated with denitrification. Soil organic carbon, pH, and ammonium nitrogen were the most critical variables affecting changes in the soil microbial community.DiscussionThese findings provide valuable information for ecological restoration and future sustainable forest management.

“…He pointed out that there are significant differences between land use change and land use transition in basic types, spatiotemporal scales, value subjects, driving factors, trajectory characteristics, and results/effects. The empirical research mainly focused on the different spatial scales of the whole country, city, county, and watershed [8,24,[28][29][30][31] to construct the transfer matrix, dynamic attitude model, GIS spatial analysis, landscape index model, etc., to study the spatiotemporal pattern of LUT [31][32][33]. Spatial econometric regression, geographic detectors, GWR, and other models were used to reveal the driving mechanism of LUT or explore the different effects of LUT [7,25,26,34].…”

The Yellow River Basin (YRB) plays an important role in China’s socioeconomic development and ecological security. From the perspective of recessive land use transition (RLUT), exploring the watershed food security (FS) coordination mechanism is of strategic significance to territorial space optimization and high-quality development. To this end, a coordinated evaluation system was built for analyzing the coupling coordination degree (CCD), spatiotemporal evolution characteristics, and driving mechanism between RLUT and FS of 74 cities in the YRB from 2003 to 2018, using methods such as the coupling coordination degree model, spatial autocorrelation analysis, and the geo-detector model. The results are as follows: (1) Spatial imbalance of RLUT and FS in the YRB is significant. RLUT has significant differences between east and west, and FS has significant differences between north and south. (2) From 2003 to 2018, the CCD between RLUT and FS increased from 0.6028 to 0.6148, maintaining a steady upward trend, and the cold and hot characteristics of spatial agglomeration are significant. (3) The CCD between RLUT and FS depends on population density, average annual temperature, and average elevation. The driving effect of natural factors is higher than the socioeconomic factors on the total basin scale, but the opposite is true on the sub-basin scale. Clarifying the spatiotemporal pattern, characteristics, and mechanism of the coupling and the coordination of RLUT and FS can provide a scientific basis for territorial space planning.
