Physiological and Ecological Responses of Kandelia obovata and Sonneratia apetala Saplings under Global Warming and Sea-Level Rise Conditions

Abstract

红树林是位于热带亚热带海岸潮间带的木本植物群落。其同时受到气候变暖和海平面上升的双重影响,是应对全球变化的敏感区域。我国乡土红树植物秋茄(Kandeliaobovata)是北半球最耐寒的红树植物;多分布于中高潮,具有较强的抗淹水能力。从孟加拉国引种的无瓣海桑(Sonneratiaapetala)具有较耐低温、高适应性和生长迅速等特点;并具有一定的淹水适应能力。 本研究运用人工增温-潮汐淹水装置,模拟未来100年平均气温升高2℃、海平面上升后潮汐淹水时间的变化(每个潮水周期淹水时间由2h延长至6h)。探讨气温增加和海平面上升条件下,秋茄和无瓣海桑苗木的生长生理响应。得到以下主要结论: 1. ...Mangroves ecosystems distribute along the coastline in tropical and subtropical regions. They are facing the extreme conditions of global climate change, including air warming and sea-level rise, etc. Kandelia obovata, the most cold-resistant species in China, which commonly distributes at the middle and high intertidal zones. After introduced from Bangladesh into China, Sonneratia apetala grew fa...学位:理学硕士院系专业:环境与生态学院_生态学学号:3332013115170
