红树林生态系统具有重要的生态系统服务功能,其多样性研究能够为生态评估与规划提供参考.深圳东冲红树林生态系统是我国红树林生态系统的重要组成部分,过去对该片区的红树林研究极少.选择深圳东冲红树林生态系统作为研究样地,对其多样性进行研究,以期为后续恢复、规划与管理提供参考.2009年,采用植物群落学介绍的传统方法对东冲红树林生态系统内代表性红树林群落和景观进行了调查.结果显示,该片区红树林面积约3 hm2,中心区域红树林得到较好的保护,其他区域的红树林被破坏并逐步退化.该湿地生态系统的群落多样性较低,平均丰富度指数为0.502,平均多样性指数为0.564,主要包括海漆、秋茄、桐花树和许树等本土红树和半红树植物.从重要值也可以看出,这些物种也是该生态系统的优势种.该生态系统的景观多样性较为丰富,其中,彩叶海漆景观是该区域的典型湿地景观,也是我国甚至全球典型的湿地景观.结果说明非常有必要保护该区域的红树林湿地生态系统,尤其是要保护该红树林物种的本土性和海漆湿地景观的典型性,必须在东冲红树林生态系统尽快启动生态分区规划,并实施以景观生态学原理为基础的生态恢复工程.

@@@@The mangrove ecosystems can provide important ecological services, and studies on the mangroves are of great meaningful, and its researches are increasing. It is crucial to study the diversity of mangroves because it’s the basis of the assessment and planning for the mangrove ecosystems. The mangrove ecosystem in Shenzhen Dongchong is an important Chinese mangrove ecosystem, which have not yet been surveyed until recent days. We carried out a field investigation in the year of 2009-2011 for this region. All the landscapes and five mangrove communities were investigated during these times using “Plant community investigation methods”. Results showed that the area of the mangroves is about 3 hm2 in 2009, and the mangroves in the central area of the ecosystem were protected, while other parts of the ecosystem had disturbed or degraded. The diversity of the mangrove community is low with a mean value of 0.502 in abundance and 0.564 in diversity. The native mangrove species included Excoecaria agallocha, Aegiceras corniculatum, Kandelia candel, and Clerodendrum inerme,which are the key species in this mangrove ecosystem according to their important value. The landscapes were diverse, with seven kinds of wetland landscape found, of which the colorful Excoecaria agallocha is the most typical mangrove landscape in China or even in the world. Results indicated it’s necessary and important to protect and restore this mangrove ecosystem especially for its native mangrove species and the typical landscape of Excoecaria agallocha, and district planning is needed and ecological restoration projects with landscape ecological philosophy is the key point for Dongchong mangrove ecosystems.
