红树林异速生长方程估算生物量研究进展

摘要

The characteristics of mangrove biomass allocation and productivity were clarified, the latest research progress in mangrove allometric equations and biomass research were introduced. Comparisons were made between common allometric equations and species-specific allometric equation. Results showed that the common allometric equation of mangrove species differed greatly among different species, but little difference among different regions, the difference of biomass depends on stocking density. The results also showed that, on a global scale, mangrove in the tropical areas have higher above-ground biomass than forest in temperate regions. Mangroves roots accumulated a lot of biomass;the ratio of above-ground to under-ground biomass was significantly lower for mangrove than for terrestrial forest.%阐明了红树林生物量分配和生产力的特性，介绍了红树林异速生长方程和生物量研究的最新研究进展，并对红树林通用异速生长方程和不同地域不同树种的异速生长方程进行了比较，结果表明：红树林通用异速方程不同树种之间差别较大，但不同地域差别不大，红树林生物量的差异取决于林木密度；在全球范围内，热带地区的红树林具有比温带地区更高的地上生物量；红树林根部积累了大量的生物量，红树林地上生物量和地下生物量的比例明显低于陆地森林。
