Construction cost (CC) is a quantifiable measure of energy demand for biomass production, and low CC is hypothesized to give an alien plant growth advantages and increase its potential to be an invader. Comparison of leaf CC and growth traits between alien and native mangroves in Shenzhen Futian Nature Reserve showed CC per unit mass (CC(mass)), carbon concentration and gross and ash-free caloric values of alien mangroves were significantly lower than those of native species, while the height and chest circumference were just the opposite. Alien species Sonneratia apetala had the lowest CC(mass) while Sonneratia caseolaris had the lowest CC(area), and were 8.99% and 32.17% lower than those of native species, respectively. Conversely, specific leaf area (SLA) of these two Sonneratia species was significantly higher than native species. Lower CC and higher SLA make the two Sonneratia species grow and spread faster than other mangroves and enhance their invasive potential.
建造成本 (CC) 是衡量生物质生产能源需求的量化指标，假设低 CC 会给外来植物带来生长优势，并增加其成为入侵物种的潜力。对深圳福田自然保护区外来和本地红树林的叶片 CC 和生长特征进行比较，结果表明，外来红树林的单位质量 CC(CC(mass))、碳浓度、总热值和无灰热值均显著低于本地物种，而高度和胸径则恰恰相反。外来物种海桑的 CC(mass)最低，而无瓣海桑的 CC(area)最低，分别比本地物种低 8.99%和 32.17%。相反，这两个海桑物种的比叶面积 (SLA)明显高于本地物种。较低的 CC 和较高的 SLA 使得这两个海桑物种比其他红树林生长和传播得更快，增强了它们的入侵潜力。
