| 摘 要： | 通过野外调查、取样和室内分析,研究了乌审旗飞播地的植被群落特征和土壤理化性质的变化。结果表明,飞播造林时间越长,地表植物盖度、种类和生物量增加越明显。同时,提高了土壤物理性粘粒含量,富集了土壤的有机质、全N、全P、速效N、速效P和速效K等养分。并且随着造林时间的延长,土壤的养分含量增加越明显。

| Abstract: | Through field investigation,sampling and indoor analysis,the features of vegetation community and changes of soil physical and chemical property have been studied in aerial seeding area in Wushen County.The results show that the longer the time of forestation by aerial seeding is,the more obvious increase is for the coverage,species and biomass of surface plant.Simultaneously,aerial seeding can enhance physical clay content of soil,and augment organic matter,total N,total P,rapidly available nutrient in the experimental ground.And the contents of soil nutrients will increase obviously as the time for forestation prolongs. |
