Community Distribution and Landscape Pattern of the Mangrove on the Qi’ao Island, Zhuhai

【Objective】 This study was aimed to analyze the structure of mangrove-forest community and its corresponding landscape characteristics, to provide valuable information for mangrove reforestation and protection, important for regional biodiversity conservation and ecological environment improvement in the future.【Method】Using Qi’ao Island as the study area, based on the datasets from interpretation of remote sensing images and field investigation, spatial-distribution of the mangrove-forest communities, population dominance and landscape pattern after low temperature damages were investigated.【Result】True mangroves are the dominant species in the study area, including two primarily exotic species(Sonneratia apetala and Sonneratia caseolaris) and three major local mangrove species, namely, Acanthus ilicifolius, Kandelia candel and Acrostichum aureum. Sonneratia apetala, with an area contribution of 85.17%, is absolutely the first dominant species. Other major species include Kandelia candel, Acrostichum aureum,
