摘要: 研究区大湾区外围丘陵浅山生态屏障，是保障大湾区生态安全的重要区域。通过分析植被遥感、土地利用和气象数据，说明研究区植被固碳量分区特征，揭示气象、植被和土地利用等因素对植被固碳量的影响。主要结论如下：(1) 研究区林地占比超过90%，是植被固碳量的主要贡献者；(2) 东江北干流南侧的东区光温水组合最为优越，植被固碳量全区最高；(3) 西江干流南侧的西区北部位于天露山和云雾山北侧雨影区，因受较低的年降水量、较高的人类活动影响，是大湾区外围生态屏障植被固碳释氧服务功能的薄弱环节，建议加强该区域生态保护和修复。
Abstract: Ecological barrier surrounding Greater Bay Area is an important area for ensuring ecological security for Greater Bay Area. Using vegetation remote sensing, land use, and meteorological data, the spatial differentiation of vegetation carbon sink was described, the influences of meteorological factors, vegetation and land use on vegetation carbon sink were revealed. The main conclusions are as follows: (1) Forest occupys over 90% of study area and is the main contributor on vegetation carbon sink; (2) The eastern sub-region (i.e. area at the south side of the main stream of Dongjiang River) has the most superior combination of light, temperature and precipitation, and the highest vegetation NPP in the entire region; (3) Due to relatively low precipitation and high population pressure, the northern part of the western region is a weak area in the vegetation productivity of the ecological barrier surrounding the Greater Bay Area. It is recommended to strengthen ecological conservation and restoration in this area.
