| Abstract: | Land consolidation has a long history, and it has currently become one of the most extensive and well-organized human activities in China. Agricultural land consolidation (ALC) will change land use patterns, vegetation coverage, as well as the physical and chemical properties of soil through a series of engineering and biological measures that in turn affect the soil conservation service of ecosystems. This paper analyzes the effects of ALC on soil conservation service in the Hilly Region of Southeast China based on the Revised Universal Soil Loss Equation (RUSLE). The main results were as follows: (1) ALC improved the soil conservation service of cultivated land; (2) variations in the soil conservation service were strongly related to rainfall, slope, area of newly converted cultivated land, earth volume of land leveling, earth volume of topsoil stripping and backfilling, reconstructed farm roads, newly built production roads, length of new irrigation systems, newly built drainage systems, number of new dams, and newly built revetments; (3) the newly established multiple regression models used in this paper could describe the relationship between the soil conservation service and significant impact factors. This study will help researchers to better understand the interactions between land management and ecosystem service provisioning as well as provide a scientific basis for policymakers as they put forward new land management policies. |
