    Progress on the Interaction Between Tree Roots and Soil Environment
    薛建輝　王智　呂祥生　

    摘　要：對林木根系與土壤環(huán)境因子相互作用的國內(nèi)外研究成果進行了綜述.總結(jié)了土壤溫度、水分、通氣性等物理因子以及土壤礦質(zhì)養(yǎng)分、CO2濃度等化學(xué)因子對根系生長的作用過程.著重介紹了土壤中A13+、O3、鹽分及干旱脅迫對根系的作用機理.分析了根系對土壤環(huán)境的作用方式和機理,包括根系分泌物的作用及細根在養(yǎng)分循環(huán)中的作用.最后提出了根系與土壤因子相互作用研究的幾個重要方向,為今后開展根系與林木生長和產(chǎn)量形成相互關(guān)系的生理、生態(tài)學(xué)機理研究提供依據(jù).
