摘要
利用景观格局指数和景观生态安全度模型等方法,探究2000—2018年海口市湿地景观生态安全格局变化特征。结果表明:过去20年,海口市湿地总面积先增加后减少,海口湿地景观生态安全度由0.121提升至0.165,表明湿地景观生态安全格局呈现出优化的趋势;不同湿地类型的生态安全格局变化存在显著差异,各类湿地的景观生态安全度与其空间分布密切相关;自然驱动力对湿地发展的影响较弱,政府采取的湿地保护和治理政策和措施为湿地景观生态安全格局优化提供了重要动力。
Landscape pattern index and landscape ecological safety model were used to explore the changing characteristics of ecological security patterns in wetland landscapes in Haikou city from 2000 to 2018.The research results showed that in the past 20 years,the total area of wetland in Haikou increased first and followed by a decrease,but the Haikou wetland landscape ecological security pattern shows a trend of optimization;the landscape ecological security of various wetlands is closely related to its spatial distribution;the influence of natural driving force on wetland development is weak,and the policies and measures adopted by the government provide for the optimization of wetland landscape ecological security pattern big momentum.
