长三角城市群乡村植被特征与生物多样性保育策略

长三角一体化绿色发展是中国的重大战略,乡村生态状况是长三角城市群生态健康发展的基础。针对长三角城市群乡村植被生物多样性保育和生态系统服务功能提升需求展开研究,调研了28个乡村共256个植物群落样地,分别进行了科属种构成和生活型分析;通过群落聚类,划分出47个群落类型和8个植被型,分析了植物群落构成和分布特征;进行了物种生物多样性分析,并将长三角乡村植被特征与城市区域和自然区域的植被特征进行比较;最后,从物种保护、生境维护、群落保育和生态美学引导等方面提出了长三角乡村植被生物多样性保育与构建的具体对策。

Rural Vegetation Characteristics and Biodiversity Conservation Strategies in the Yangtze River Delta Urban Agglomeration

: The integrated green development of the Yangtze River Delta is a long-term major strategy. The rural ecological status is the basis for the healthy development of the Yangtze River Delta urban agglomeration. This study focuses on the expansion of demand for rural vegetation biodiversity conservation and ecosystem service functions in the Yangtze River Delta urban agglomeration. A total of 256 plant communities in 28 villages were investigated, and the composition of family, genera and species and life forms were analyzed respectively; through clustering, 47 community types and 8 vegetation types were divided, and the composition and distribution characteristics of plant community were analyzed; and then it analyzed the species biodiversity and compared the characteristics of rural transformation in the Yangtze River Delta with the vegetation characteristics of urban areas and natural areas. Finally, specific countermeasures for biodiversity conservation and reconstruction of the Yangtze River Delta rural vegetation was proposed in terms of species protection, habitat maintenance, plant community conservation, and ecological aesthetics guidance
