黄河三角洲生物多样性保护与可持续利用的研究

根据1996-1998年对黄河三角洲环境质量、生物多样性等进行的全面、系统的调查与监测结果.重点研究了该区域大气、河流、湖泊、水库、浅海滩涂环境质量,海洋生物多样性、淡水生物多样性、陆生和海岛高等植物多样性、陆栖动物多样性与特点,分析了其破坏状况和原因,提出了生物多样性保护对策和可持续利用途径.黄河三角洲生物多样性调查研究结果显示:近海海域共鉴定出浮游植物116种、浮游动物79种、底栖动物222种、潮间带动物192种、鱼类112种,其他重要海洋动物11种;淡水水域共鉴定出浮游植物291种、浮游动物144种、底栖动物69种、鱼类102种;陆域和海岛共鉴定出高等植物608种、无脊椎动物922种、脊椎动物325种,有4种动物为山东新记录种.该区域湿地植被群丛多样,鸟类多样性丰富,重点保护鸟类种类多、种群数量大. 

Study on the Biodiversity Protection and Its Sustainable Use in the Yellow River Delta

Based on the comprehensive and systematic investigation and monitoring results made from 1996 to 1998 of environmental quality and biodiversity in the Yellow River Delta (YRD),the environmental quality of the atmosphere,rivers,reservoirs,lakes and shallow sea beach lands in the area has been studied,and so have the diversities and their features of marine living things,fresh water living things,terrestrial and island higher plants and terrestrial animals.Their damage state and causes have also been analyzed.In addition,the countermeasures for protecting biodiversity and the way for its sustainable use have been put forward.The results obtained are as follows:in the sea areas near the YRD have been identified 116 species of phytoplankton,79 species of zooplankton,222 species of zoobenthos,192 species of intertidal zone animals,112 species of fish and 11 species of other marine animals;in the fresh water areas 291 species of phytoplankton,144 species of zooplankton,69 species of zoobenthos and 102 species of fish;and in the land and island areas 608 species of high plants,922 species of invertebrated,and 325 species of vertebrates,4 of them are new records in Shandong Province.In the wetlands of the area there are diverse vegetation association,rich bird diversity,many key protected bird species and large numbers of sub\|populations.
