| 摘 要： | 在湖南省会同县森林生态系统定位站小集水区杉木人工林生态系统中,对植被、土壤和水分的营养元素(N,P,K,ca,Mg)进行分析测定,结果表明:系统中植被的养分含量,因器官类型、生长季节和年龄的不同而不相同;土壤养分含量,因立地条件类型的差别而有明显的差异;水分中的营养元素,随天气状况、降水性质和时间的变化而发生变化,并阐述了进行此类研究的方法及应予引起注意的问题。可供进行类似研究时参考。

| Abstract: | Analysis has been made of the nutrient elements N, P, K, Ca, Mg in the plant, soit and water in the China fir plantation watershed ecosystem at the Huitong Forest Ecosystem Research Station of Central-South Forestry College Results indicate that the nutrient contents vary with growth seasons, organ types and ages in plant, with site types in soil, and with regimes of weather and precipitation in water. Moreover, the methodology of the research has been discussed. |
