粤港澳大湾区典型滨海河口景观植物选择策略研究 ——以珠海西部河口湿地为例

粤港澳大湾区9+2城市群是中国开放程度最高、经济活力最强的区域之一，是以生态优先，绿色发展理念，建设美丽湾区为引领，着力提升生态环境质量为目标的生态文明建设区域。珠海处于粤港澳大湾区中最典型的珠江口地区，以该区域城镇发展最快、规模最大的珠海西部河口湿地为研究对象，对其植物景观群落的观赏性、耐盐性、抗风性、耐涝性、耐旱性和耐污性等特质进行综合分析，结合对典型河口湿地景观植物种类及立地条件开展调查，对河口湿地植物立地影响因子进行了定量分析与评价。通过主成分分析法(PCA)，综合评估现阶段该区域湿地景观植物的适宜性、观赏性，并提出今后适宜河口环境的景观植物种类，为河口湿地景观植物选择提供技术支撑。

The Strategy of Selection of Landscape Plantsat Typical Coastal and Estuarine Area in theGuangdong-Hong Kong-Macao Greater Bay Area:A Case Study of Western Estuarine Wetland ofZhuha

The 9+2 city agglomeration of the Guangdong-Hong Kong-Macao Greater Bay Area is one of the most openand economically vigorous regions in China. It is anecologicalcivilization construction area characterized by the concept ofecological priority and green development, the construction of thebeautiful Bay Area, and focusing on improving the environmentalquality. Zhuhai is located at the most typical estuarine area of thePearl River in the Guangdong-Hong Kong-Macao Greater BayArea. The most fast-developing and extensive estuarine wetlands inthe western part of Zhuhai were selected as the research objectivesto comprehensively analyze the landscape plants by their featuresof ornament, salt tolerance, wind resistance, inundation tolerance,drought tolerance and pollution resistance. Combined with theinvestigation of landscape plant species and site conditions intypical estuarine wetlands, the factors influencing estuarine wetlandplants were quantified and evaluated. The principal componentanalysis (PCA) was used to comprehensively evaluate thesuitability and ornamental value of wetland landscape plants in theregion at present, propose suitable landscape plants for estuarineenvironment, and provide technical support for the selection oflandscape plants in estuarine wetland regions.
