摘要

淤泥质滩涂碳汇是海岸带蓝碳的重要组成部分。微藻作为淤泥质滩涂的主要初级生产者,对固碳和储碳起重要作用,但目前对我国淤泥质滩涂微藻群落组成及其碳储量的研究较缺乏。本研究于2021年8月采集了浙江温岭隘顽湾淤泥质滩涂的微藻样品,进行显微镜检并基于细胞生物体积估算其碳储量。调查区域内共检出微藻4门59种,群落组成以硅藻占据绝对优势,主要优势属包括圆筛藻Coscinodiscus、菱形藻Nitzschia、布纹藻Gyrosigma和针杆藻Synedra等。各调查站点的微藻丰度和生物量表现出明显的空间异质性,这可能与陆源输入有关;此外,闸口强水流冲击形成的潮沟也可能影响微藻的沉降与再悬浮过程。根据微藻的生物量估算,调查期间隘顽湾淤泥质滩涂微藻碳储量约为2 134 t,其中浮游型微藻的沉降输入占比约为60%。本研究结果强调了浮游型微藻的沉降输入对泥滩微藻群落组成及碳储量的重要影响,可为淤泥质滩涂碳汇来源的精确评估提供科学依据。

Abstract

The carbon sink capacity of muddy tidal flat plays a significant role in coastal blue carbon ecosystems. Microalgae, as the main primary producers in these habitats, are key contributors to carbon sequestration and storage. However, the community composition and carbon stock of microalgae in China’s muddy tidal flats remain poorly understanding. Here, microalgae samples were collected from muddy tidal flat of Aiwan Bay, Wenling, Zhejiang Province in August 2021. The microalgae were identified using an inverted microscope, and their carbon stock was estimated based on cellular biovolume measurements. A total of 59 species from 4 phyla were identified, with diatom being the overwhelmingly dominant group. The most abundant genera included Coscinodiscus, Nitzschia, Gyrosigma, and Synedra. The abundance and biomass of microalgae showed pronounced spatial heterogeneity across sampling sites, likely influenced by terrestrial inputs. In addition, tidal creeks caused by strong outflow from water gates might have affected the settlement and resuspension of microalgae. Based on biomass calculations, the regional microalgal carbon stock in muddy tidal flat of Aiwan Bay was estimated at approximately 2 134 t, with approximately 60% derived from settled planktonic microalgae. This study underscores the significant impact of phytoplankton on microalgal community composition and carbon storage. These findings provide valuable insights for assessing carbon sinks in muddy tidal flats and contribute to a better understanding of blue carbon dynamics in coastal ecosystems.

On tidal flats, tidal creeks are the important microlandform which varies greatly. The sediments of tidal flats usually are altered or destroyed by lateral migration and sway of tida! creeks, which affects the stability of tidal flats. Therefore, studying tidal creeks and their sediments is very useful for exploiting tidal flats, carrying out coast engineering projects and analysing ancient tidal creeks and tidal sediments.At home and abroad there are a lot of papers and works dealt with tidal creeks and sediments therein, however, genetic classification of tidal creeks and factors affecting their development haven’t been yet studied comprehensively. This paper discusses these aspects based on data obtained from literature and field observation.According to the principles of genetic classification, the tidal creeks in the world can be classified as follows:1. Tidal creek scoured by the currents on tidal flatThis is the creek which develops on the surface of tidal flat and is similar to the gully developed on mountain slope in development mechanism.2. Tidal creek scoured by the converged tidal currents.This is the creek formed by tidal currents which were locally concentrated or focused.3. Tidal creek inheriting the runoff from landAn inheriting tidal creek it the creek which originally inherited the rill formed by the small-scale runoff from land to tidal flat and then became tidal creek under the erosion of ebb- and flood-tide currents.4. Tidal creek scoured by the tide currents between lagoon and open sea.This is a kind of creeks which is relatively large and connects the lagoon with the open sea.In different parts of the world tidal creeks develop very differently. The main factors affecting the development of tidal creeks are as follows:(1)Tidal range.(2)The width of tidal flat and its relief.(3)Vegetation.(4)Mud content of sediment of tidal flat.(5)The rate of sedimentation.(6)The process of ebb- and flood-tide currents.(7)Human effect.

Diel primary production patterns of intertidal microphytobenthos (MPB)have been attributed to short-term physiological changes in the photosynthetic apparatus or to diel changes in the photoautotrophic biomass in the sediment photic layer due to vertical migration. Diel changes in primary production and vertical migration are entrained by external factors like photoperiod and tides. However, the role of photoperiod and tides has not been experimentally separated to date. Here, we performed laboratory experiments with sediment cores kept in immersion, in the absence of tides, with photoperiod or under continuous light. Measurements of net production, made with O microsensors, and of spectral reflectance at the sediment surface showed that, in intertidal sediments, the photoperiod signal was the major driver of the diel patterns of net primary production and sediment oxygen availability through the vertical migration of the MPB photoautotrophic biomass. Vertical migration was controlled by an endogenous circadian rhythm entrained by photoperiod in the absence of tides. The pattern progressively disappeared after 3 days in continuous light but was immediately reset by photoperiod. Even though a potential contribution of a subjective in situ tidal signal cannot be completely discarded, Fourier and cross spectral analysis of temporal patterns indicated that the photosynthetic circadian rhythm was mainly characterized by light/dark migratory cycles.
