摘要
在吉林省中西部农田防护林集中分布的13个县(市)设置标准地,调查林带土壤特征和林带林木生长状况。通过林带土壤理化性状的对比分析与研究,发现林带土壤含水量明显低于农田,土壤容重偏高,盐碱地分布地区的林带土壤pH值上升。
The sample- plot survey was conducted for farmland shelterbelt in 13 counties （municipal） of western region of Jilin Province, China, which investigated the soil characteristics of physics and chemistry and trees growth in the shelterbelt. Through contrast analysis with the farmland, it concluded that soil moisture content under shelterbelt was lower observably, soil bulk density was higher then the farmland, the pH values of saline and alkali soil under the shelterbelt were rise.
