摘要：
Impact of gap sizes created by an ice storm on soil properties was analyzed. Twelve natural treefall gaps were identified in a C. lanceolata stand in northern Guangdong Province, South China in March 2008. Transmitted light, soil moisture, soil organic matter, total N, total P, alkalized N, available P, urease, phosphatase and catalase were measured. Gap size was significantly positively correlated with canopy openness, and canopy openness significantly negatively related to soil organic matter, total N, alkalized N, urease and catalase. Canopy openness was unrelated to soil moisture, total P and available P. Results indicate that in the C. lanceolata stand, large canopy openness gaps may result in a microsite with poor fertility and a decrease in soil organic matter, N, urease and catalase.
