Developments and applications of terrestrial biosphere model [PDF]
, 2020 Exchanges of energy and matter between terrestrial biosphere and atmosphere and hydrosphere create critical feedbacks to Earth’s climates. To quantify how terrestrial ecosystems respond and feedback to global changes, terrestrial biosphere model (TBM ...

A Review on Litter Decomposition in Forest Ecosystem [PDF]
, 2006 系统评述森林凋落物的分解过程、凋落物分解及养分释放的影响因素、分解研究的方法等。森林凋落物的分解既有物理过程,又有生物化学过程,一般由淋溶、自然粉碎、代谢作用等共同完成。凋落物分解过程先后出现分解速率较快和较慢2个阶段,元素迁移一般呈现淋溶-富集-释放的模式。凋落物分解主要受气候、凋落物性质、微生物和土壤动物的影响,气候是最基本的影响因素,常用实际蒸散(actualevapotranspiration简称AET)作为指标。凋落物分解速率呈明显的气候地带性,与温度、湿度等紧密相关。从全球尺度来讲 ...

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 ...

土壤呼吸作用时空动态变化及其影响机制研究与展望. [PDF]
, 2009 测定不同陆地生态系统土壤呼吸速率及其时空波动,阐明其影响因子,对于全球碳素平衡预算和全球变化潜在效应估计是最为基本的数据。然而,有关土壤呼吸作用变异性及其影响因素的知识仍存在局限性,一些关键的过程和机制还有待阐明。该文综述了近年来土壤呼吸作用时空动态规律、影响机制和模拟方面的研究进展,指出环境因子和生物因子共同驱动着土壤呼吸作用的时间动态变化;土壤呼吸作用在不同时间尺度上还具有明显的空间异质性,这主要是植被覆盖、根系分布、主要的环境因素和土壤特性空间分布的异质性造成的 ...

The impacts of habitat heterogeneity of mangroves on mollusks diversity at Dongzhaigang Bay, Hainan [PDF]
, 2016 包括软体动物在内的大型底栖动物是红树林生态系统的重要组成部分，几乎在所有的红树林生境类型中都能够发现它们的存在，其在红树林中占据了重要的生态位，通过穴居、取食等活动改变着红树林有机物循环的物理和化学过程，对红树林生态系统的结构和功能的维持具有非常重要的作用，是红树林生态系统中食物网的重要环节。本文选取了海南省东寨港国家级自然保护区内三个不同地点的红树林从空间尺度方面对其中的软体动物分布进行了研究。此外还比较了不同地点的红树植物群落内软体动物分布的特点。 选择了海南东寨港的湾口(塔市)、中部(后排 ...

Multiple‐stressor effects on leaf litter decomposition in freshwater ecosystems: A meta‐analysis
Functional Ecology, Volume 38, Issue 7, Page 1523-1536, July 2024.Read the free Plain Language Summary for this article on the Journal blog. Abstract Recent years have witnessed a surge in research on the effects of multiple stressors in freshwater ecosystems. While studies have increased, the synthesis of their findings into a broader understanding of ecosystem‐level effects remains an ongoing endeavour. Leaf litter
