英文摘要:

In semiarid terrestrial ecosystems, optimized eco-rehabilitation strategies, such as land preparations and planting vegetation, are keys to achieve a successful ecological restoration. Land preparations and vegetation are supposed to have the coupled and respective impacts on soil ecosystem services, which are still unclear now. In this study, eighteen experimental plots with six different combinations and repetitions of land preparations and vegetation were built in the Chinese Loess Plateau in 2014 and soil moisture storages (SMS), soil carbon stocks (SCS) and other soil nutrient stocks were calculated at 0-100 cm, also the effects of land preparations and planting vegetation on soil eco-hydrological services are analyzed by mathematical methods. The results show that leveled ditches-M. saliva had the highest SMS (125 mm) while zig terraces-P. tabulaefonnis had the lowest values (88 mm). Fish-scale pits-P. tabotaefonnis had the most SCS (9804 g/m(2)) and leveled ditches-M. saliva had the lowest values (8163 g/m(2)). For soil nutrient stocks, leveled benches-C. inicrophylla and fish-scale pits P. tabulaeformis had the highest levels while leveled ditches-M. saliva had the lowest values. The partial redundancy analysis (pRDA) and variation partitioning (VP) analysis indicated that soil nutrient stocks were most affected by the coupling effects of land preparation and vegetation. SMS at surface (0-10 cm) were mainly affected by precipitation (58.8%). Furthermore, SMS at subsurface (10-60 cm) and deep soil layer (60-100 cm) were affected by the shared effects of vegetation and land preparation (613%), and vegetation (72.2%), respectively. The findings quantified the coupling and respective contributions of vegetation restoration and land preparation to soil eco-hydrological services and demonstrate that the optimal combination of eco-rehabilitation strategies can achieve a sustainable land restoration.
