摘要
通过对苏北海堤杉木杨树混交林及杉木纯林林木生长情况、土壤理化性质及酶活性的分析表明:混交林林木生长、林地土壤结构状况和养分含量均好于纯林;提高土壤酶活性及肥力水平,是有效防止杉木林多代连栽林地地力衰退的有效方法,可在海堤防护林更新过程中逐步推广。
The trees growth, soil physical and chemical characters and enzyme activities under mixed forest of Chinese fir and poplar（Populus deltoids cv. ＇Lux＇） and pure stand of Chinese fir were analyzed. The results indicated that trees growth,soil structural property and soil nutrients in mixed forest were better than that in the pure one, and the soil enzyme activities were enhanced. Thus this model was an effective measure to prevent decrease of the soil fertility of forest land for the continuously planted Chinese fir, and it is worth planting in the coastal areas in the northern Jiangsu province.
