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。
The nutrient elements (N, P, K, Ca, Mg) in vegetation, soil and water were analyzed and determined in the Chinese fir plantation ecosystem of small catchment area in Huitong County, Hunan Province. The results showed that in the system The nutrient content of vegetation is different due to different organ types, growing season and age. The nutrient content of soil is obviously different due to the different types of site conditions. The nutrients in water vary with the weather conditions, the nature of precipitation and the time Changes and changes, and describes the method of such research and should pay attention to the issue. Reference for similar research.
