Field Study on Effects of Simulated Sea Level Rise on Main Processes of Organic Carbon in Kandelia obovata Mangrove Ecosystems [PDF]
, 2015 本研究以厦门曾营海岸三个不同高程样地的秋茄红树林为研究对象，在模拟海平面上升80cm红树林（SLR80cm）、模拟海平面上升40cm红树林（SLR40cm）以及对照红树林（SLR0cm，大约相当于福建九龙江口红树林的滩面高程），探讨海平面上升对秋茄（Kandeliaobovata，以前学名为Kandeliacandel）红树林生态系统主要有机碳过程的影响。 SLR80cm样地的植株矮小、林相稀疏，生长状况明显不如SLR40cm和SLR0cm样地。各样地植株的生物量以及年增量总体均呈现出SLR0cm ...

Shuitu Baochi Xuebao, 2006 从土壤N，P，K及土壤有机质等方面研究了人为干扰（包括放牧、开垦和禁牧）对典型草原生态系统土壤养分含量的影响。研究结果表明：开垦和放牧会导致土壤，主要是表层土壤养分含量的下降，而开垦对土壤养分的影响更为明显；禁牧会提高土壤各种养分的含量，而且随着禁牧时间的增加，土壤养分含量有逐渐增加的趋势。对深层土壤养分含量没有明显影响。同时，草原生态系统土壤全氮、速效氮及有机质含量与土层深度呈明显的负直线相关关系；速效K、速效P含量则与土壤深度的关系符合二次幂函数关系；全磷含量随深度的增加有逐渐升高的趋势 ...

Functional Ecology, Volume 39, Issue 12, Page 3504-3516, December 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Nitrogen (N) deposition strongly affects litter decomposition and nutrient release, thereby reshaping carbon cycling in terrestrial ecosystems. Although most studies have focused on above‐ground litter, the effects of N addition on fine root decomposition and their ...
