摘要
利用RS和GIS技术,通过对海口市建成区景观格局与植物多样性的分析表明:海口市建成区景观格局在各区域中,各个指数呈现出一致的变化规律,城市化水平从龙华区、美兰区、琼山区、秀英区依次降低,整体破碎化程度较高;城市植物物种Shannon-Wiener多样性和Pielou均匀度指数也表现出同样的变化趋势。
In this study, the RS and GIS techniques were used to study the landscape pattern and plant diversity in Haikou built-up areas. The results showed that, the landscape pattern of Haikou built-up areas in all areas, the landscape index showed a consistent change rule, the urbanization level of the built-up areas decreased from Longhua District, Meilan District, Qiongshan District and Xiuying District, and the overall fragmentation degree was high. The Shannon-Wiener diversity and Pielou evenness index of urban plant species also showed the same trend.
