越南红树林的种类、分类和面积

摘要

红树是分布于热带与亚热带陆海之间咸水环境中的乔木和灌木.越南地跨红树林的两大生物地理区域,拥有典型的热带和亚热带红树林,并在地理上呈现出南北两端集中分布的特征.几十年来,越南的红树林因越南战争期间落叶剂的危害和农业、海水养殖业、工业、城市化、基础设施建设等人口扩张所导致的发展而持续衰退,且衰退速度越来越快.本文概述了越南红树林的种类、分布、面积及其变化,以期为探索红树林的可持续发展提供参考资料.%Mangroves are trees and shrubs distributed in saline environment along coast in trop-ical and subtropical regions.Vietnam's territory spans these two biogeographical regions of mangroves and has typical tropical and subtropical mangroves,which are geographically distrib-uted across the north and south of the country.For decades,mangroves in Vietnam have been in a trend of degradation and decline more rapidly as a result of the dangers of fallen leaves during the Vietnam War and the development of population expansion such as agriculture,maricul-ture,industry,urbanization and infrastructure.This paper summarizes the species,distribu-tion,areas and variation of mangroves in Vietnam,with a view to provide reference materials for exploring the sustainable development of mangroves.
