明确大尺度物种丰富度的分布格局及其影响因素一直是生态学及生物地理学领域的核心议题之一,其对于预测全球环境变化背景下生物多样性的响应和制定减少生物多样性丧失的保护方案有着重要意义。本文基于全国芦苇(Phragmites australis)沼泽野外调查数据,结合气候、地理、土壤等环境因子,探讨了中国芦苇沼泽植物物种丰富度的分布格局及其驱动机制。结果表明:(1)中国的芦苇沼泽植物物种丰富度总体表现为亚热带湿润区和温带湿润半湿润区较高,青藏高原区、温带干旱半干旱区和滨海区较低的特点;(2)芦苇沼泽植物物种丰富度与年降水、土壤有机碳、土壤总氮、纬度均呈显著正相关,而与年均温、最冷月最低温、土壤pH值、海拔之间表现为显著负相关;(3)土壤因子特别是土壤pH值是影响芦苇沼泽植物物种丰富度的最主要因素,其次分别为淹水状况、气候因子和地理因子;(4)结构方程模型结果表明土壤因子、淹水状况和气候因子直接影响植物物种丰富度,而地理因子通过调控土壤因子、淹水状况与气候因子间接影响植物物种丰富度。总体而言,中国芦苇沼泽植物物种丰富度具有空间异质性,其分布格局受到多种因素的共同影响,土壤因子是影响植物物种丰富度分布格局的关键环境因素。

吉林省沼泽湿地生物多样性丰富,然而近年气候变化导致吉林省沼泽湿地面积减少,物种栖息地遭到破坏,因此气候变化对沼泽湿地植物多样性影响研究对沼泽湿地保护和恢复至关重要。本文基于吉林省沼泽湿地6601个样点的30种优势植物分布数据和19个环境因子数据,利用SSDMs模拟了现状年(1981—2010年)吉林省优势沼泽湿地植物物种丰富度格局,对各物种分布的主要驱动因子进行识别,并对21世纪末(2071—2100年)3种气候情景(SSP1-2.6,SSP3-7.0,SSP5-8.5)优势沼泽湿地物种的分布进行预测。结果表明:影响吉林省优势沼泽湿地植物分布的主要环境因子是最湿季度的降水量、土壤pH和最温暖月份的最高温度。吉林省优势沼泽湿地植物分布不均匀,东部物种丰富度高于西部,丰富度最高的地区为敦化市;未来气候变化情景下,吉林省优势沼泽湿地植物分布范围缩小,物种丰富度降低;吉林省优势沼泽湿地植物大部分现存已经被保护,模拟发现的一些适宜分布区和未来气候风险区,在保护网络建设时应予以考虑保护。期望研究结果为吉林省沼泽湿地保护提供科学依据。

Review of Rapid Transformation of Floodplain Wetlands in Northeast China： Roles of Human Development and Global Environmental Change

Chinese Geographical Science 2018年第4期28卷 654-664页

作者： YU Xiaofei DING Shanshan ZOU Yuanchun xue zhenshan LYU Xianguo WANG Guoping Key Laboratory of Wetland Ecology and Environment Northeast Institute of Geography and Agroecology Chinese Academy of Sciences Changchun 130102 China University of Chinese Academy of Sciences Beijing 100049 China

Northeast China is the region with the largest area of wetlands in China. The Sanjiang Plain and the Songnen Plain are large freshwater marsh distribution regions that are affected by climate warming and by the increasing frequency and density of extreme weather and are the regions most subject to disturbances by human activities in Northeast China. The wetlands of the Sanjiang Plain and the Songnen Plain have shrunk severely in the past 60 years, and wetland functions have been reduced substantially because of climate change, unreasonable land use, fire episodes, engineering and construction works and urbanization. Large-scale agricultural development started in the 1950 s has been the most important driving factor for wetland loss and degradation in the Sanjiang Plain. Water shortage has been the most important factor for degradation and fragmentation of wetlands in the Songnen Plain. To mitigate wetland degradation and better protect wetlands, special regulations, long-term mechanisms and technical support of wetland protection should be established. A wetland compensation program should be implemented, and technologies for increasing the adaptive capacity of wetlands should be developed. Moreover, it is most important to find the balanced threshold between agricultural development and wetland protection.

Impacts of Climate and Nutrients on Carbon Sequestration Rate by Wetlands: A Meta-analysis

引用

Chinese Geographical Science 2020年第3期30卷 483-492页

作者： CHENG Caifeng LI Min xue zhenshan ZHANG Zongsheng LYU Xianguo JIANG Ming ZHANG Hongri College of Geomatics Shandong University of Science and TechnologyQingdao 266590China Northeast Institute of Geography and Agroecology Chinese Academy of ScienceChangchun 130024China

Global numerous wetlands are the most productive ecosystem and have high carbon sequestration potential to mitigate increasing CO2 in the atmosphere. However, few are available on estimating average carbon sequestration rates by global wetlands(Carbonsq) at century timescale. In this article, Carbonsq data of 473 wetland soil/sediment cores from the literatures were collected in detail by the meta-analysis method. These cores were no more than 300 years old and spanned a latitudinal range from 33.6° S to 69.7° N. Globally, the average Carbonsq was 185.2 g/(m^2·yr) regardless of wetland types. Carbonsq varied remarkably between wetland types and ranked as an order of salt marsh(247.7 g/(m^2·yr)) > mangrove(229.8 g/(m^2·yr)) > freshwater marsh(196.7 g/(m^2·yr)) > peatland(76.9 g/(m^2·yr)). Carbonsq was positively related to mean annual temperature(AMT) and annual precipitation(Pre). Nitrogen was the most common and primary factor controlling Carbonsq regardless of wetland types.
