| 摘 要： | 土壤分室是N、P、K的主要贮存库。分别占土壤一植被组分中该元素总贮量的90．2%、98．7%。和99．6%．土壤分室中，N、P质量分数和贮量随着深度的增加而减少，而K在不同土层差异不明显；果树分室中．三元素质量分数最高为叶片，贮量最高为根部；地被物分室中．三元素质量分数地上部高于地下部，贮量N素地下部高于地上部，而P、K地上部高于地下部．

| Abstract: | In soil part system, which is the main storeroom of N, P, K, the storage accounts for 90.2%, 98.7% and 99.6% , respectively, of the total in soil vegetation system, and with the increasing of depth the mass fractions and storage of N, P decrease but those of K do not vary obviously. In fruit tree part system, the highest mass fractions of N, P, K are in the blade and the highest storage is in the root. In vegetation (grass) system, the mass fractions of N, P, K aboveground are higher, and the storage of N underground is higher but that of P, K aboveground is higher. |
