Understory vegetation patterns and soil characteristics of a Pinus thunbergii plantation in mountainous land of Shandong Province
摘要
Abstract
Undergrowth vegetation and soil evolution are essential prerequisites of plantation growth and com-munity structure, which then determine the stability and health of a plant community. To evaluate community succession patterns of plantation ecosystems along with stand age changes, plantation and soil ecosystem changes in forests were analyzed using a spatial sequence approach instead of a temporal sequence. Pinus thunbergii plants in the mid-southern mountainous lands of Shandong Province were the test materials, and plant community structure, understory vegetation, soil physicochemical properties, and microbial community characteristics were determined.Results showed that(1)Soil available P was significantly different for differ-ent stand ages (P<0.05). For different stand ages, soil available K was also significantly different with 30 years being highest and 6 years lowest(P<0.05). Total N at 50 years was significantly lower than at 6 and 30 years(P<0.05); whereas, available N at 30 years was significantly higher than at 6 and 50 years(P<0.05). (2)At different stand ages, soil invertase and cellulase activities were significantly different(P<0.05)with 30 years being highest and 50 years lowest. Soil urease activity was significantly greater at age 50 than at 6 years and 30 years(P<0.05)and decreased with the increasing stand age.(3)For soil microbial diversity, the order of change for stand age was 6 year-old>50 year-old>30 year-old with Proteobacteria, Actinobacte-ria,and Acidobacteria having the greatest abundance.(4)The diversity of undergrowth vegetation decreased as stand age increased. These results have theoretical significance in guiding the management of Pinus thunbergii plantation scientifically.关键词
