以深圳市X涌为例浅谈城市黑臭水体治理

从控源截污、清淤修复、原位修复和活水循环四个方面对深圳X涌黑臭水体治理进行了全方位考虑,虽取得一定效果,但还没彻底解决黑臭。但通过工程总结,希望给后续相关工程一些启示。河道的截污是消除黑臭的根本,但截污要从污水来源、传输、处理终端每个环节进行分析;同时需要采用河道清淤、补水、原位修复等手段综合治理,方能初步改善河道水质。

Mesozooplankton species distribution in the NW and N Iberian shelf during spring 2004: Relationship with frontal structures

We have analysed the mesozooplankton community structure in the southern Bay of Biscay shelf and its relationship with the hydrographic conditions during spring 2004. According to thermohaline characteristics, we observed two frontal zones of distinct origin along the shelf (around 7° and 3°W), that allowed us to differentiate three different hydrographic domains. The westernmost part of the shelf (WC), defined by the presence of relatively warm and salty water related to the presence of the Iberian Poleward Current (IPC), the easternmost region (EC), characterized by colder and fresher water and subject to the influence of freshwater inputs from the Adour river in the French coast, and a region in the Central Cantabrian Sea (CC), where thermohaline characteristics were intermediate between these two extremes. The mixing layer depth (MLD) regime in these areas was also different: the WC region was characterized by a mixed water column, whereas in the EC region the river discharges produces stratification of the upper meters of the water column (< 10 m); in the CC region, we found a distinct vertical mixing regime that separated coastal (stratification) from shelf (mixed water column) stations, giving rise to a notorious across-shelf front. We found a good match between the aforesaid hydrographic regions and the distribution of mesozooplankton species composition and community assemblages: the Mantel correlation between physical variables and mesozooplankton distribution was highly significant (n = 63, r = 0.70, α < 0.001). In the WC region, the community was dominated by Paracalanus parvus, Oithona helgolandica, Acartia clausi and Clausocalanus pergens, while in the EC region the most dominant species were Noctiluca scintillans, Oncaea media and Temora longicornis. The CC region showed similar composition of copepods than the WC region, but larvaceans (Oikopleura spp. and Fritillaria spp.) were more abundant in the CC region than in the WC region. Within each zone, the relative abundances of the dominant species differed between coastal and shelf locations.

Patchiness in the Fly River plume in Torres Strait

Oceanographic studies were carried out from August 1994 to March 1995 on the intrusion of the Fly River plume in Torres Strait. Measurements at offshore coral reefs revealed an event of decreased salinity (≈24) while salinity of the water over the reefs fluctuated between 30–34 the rest of the time. Modelling suggests that this event resulted from the reversal of longshore currents advecting old river plume water back past the river mouth. There the new river water mixed with the old river plume water generating a patch of low-salinity water. While such events may be infrequent, they have the potential to leave a terrestrial signature on offshore coral reefs, in terms of (1) an input of terrigenous sediment and (2) the possible incorporation of riverine particulate metal into the food chain. The impact during an intrusion event may be significant. In the long term the riverine material is diluted in calcareous sediment produced throughout the year by bio-erosion of coral reefs.
