贵州百里杜鹃自然保护区杜鹃林枯落物储量及持水功能

open access: yesShuitu Baochi Xuebao, 2018
为揭示贵州百里杜鹃自然保护区人工抚育及旅游管理对杜鹃林水土保持功能的影响,选择轻度、中度、重度干扰强度的杜鹃林枯落物层作为研究对象,采用室内浸泡法对不同干扰强度的杜鹃林枯落物层水文功能进行研究。结果表明:(1)杜鹃林枯落物储量随干扰强度增加呈降低趋势,随分解程度增加呈极显著升高趋势;自然含水率随干扰强度增加呈降低趋势,随分解程度增加总体呈升高趋势。(2)杜鹃林枯落物最大持水量随干扰强度增加呈降低趋势,随分解程度增加呈极显著升高趋势。枯落物最大拦蓄量、最大拦蓄率 ...

Dynamics of nutrient and energy for fine roots of Casuarina equisetifolia plantations on coastal sandy soil [PDF]

open access: yes, 2007
2005年1月到2005年11月对福建省惠安县赤湖林场不同林龄木麻黄人工林细根养分和能量的季节动态进行了观测,结果表明:(1)6种元素的含量在不同林龄木麻黄细根中都具有明显的季节变化。各林龄细根的N含量一般在冬夏季节较高,且死细根的N浓度高于相同林龄的活细根,除12林龄活细根P浓度在7月份有最大值外,其他各林龄活、死细根在一年中呈波动性下降,K含量在冬季较高,而在其他季节变化幅度不大,除5林龄活细根和18林龄死细根在3月份和7月份有两个峰值外,其他林龄细根Ca含量随季节变化较小 ...
