中文摘要：

林下养鸡为创新农作模式之一，可产生巨大的生态效益、经济效益和社会效益。为探究林下养鸡的可持续性，在浙江省临安市中部於潜镇横路乡，通过典型样地法调查鸡群的分布对林地小气候、林地土壤化学性质的影响，结果表明，山核桃林较竹林更适宜于养鸡，随放牧强度的增加，土壤速效钾含量、pH值增高，速效磷含量下降，适度放牧可增加土壤的有机质含量。

英文摘要：

As one of innovative cropping system, free range chicken in the undergrowth had brought great economic, social and ecological benefits. To explore the sustainability, investigation of free range chicken in the undergrowth was carried out by way of sampling plots survey in Henglu town, Lin＇an, Zhejiang province. The effect of free range chicken on woodland microelimate and the soil chemical properties of forest soil were studied. Results showed that it was more suitable for chicken in Carya cathayensis than in Phyllostachys praecox. With increase of grazing intensity, soil available phosphorus contents deduced, while soil available potassium content and pH value began to increase. Soil organic matter contents could also be raised by moderately grazing.
