Interacting Effects of Land Use Type, Soil Attributes, and Environmental Factors on Aggregate Stability

Soil erosion and surface pollution near reservoirs can adversely affect water quality safety. aggregate stability is an important predictor of soil loss resistance that strongly influenced by land use. This study therefore aimed to identify factors affecting provide empirical theoretical insights could guide the development management measures increase quality, optimize use, maximize sustainability. focuses on around Shitoukoumen Reservoir in China examines effects six use types, eleven physicochemical properties, five environmental factors. Ninety-four sets samples were collected 2021 for analysis aggregates properties. Particle size classification was carried out using wet sieve method four indicators calculated evaluate stability: stable (WSA), mean weight diameter (MWD), geometric (GMD), fractal dimension (D). Descriptive statistics geostatistics used explore spatial distributions reservoir influence properties studied correlation path analysis. The conclusion indicates type significantly affects stability. most found paddy fields (WSA = 0.77, MWD 0.76, GMD 0.57) forests 0.75, 0.55), followed orchard, irrigated land, grassland. Aggregate worst upland sites 0.61, D 2.28), where highly fragmented. There clear correlations between all indicators. characteristics with strongest organic matter, pH, clay content, total nitrogen, temperature changes. Path revealed some indirectly, particularly complex relationships clay, pH. In conclusion, type, these factors, especially temperature, reservoirs. future, it necessary appropriately change into forest add fertilizer improve quality.
