澳門為何建不到深水港？
熊神進・2026-07-30Feng Shui Analysis of Building a DeepWater Port in MacauIt is widely recognized that Macau suffers from inherent geographical disadvantagesmdash;its waterways are simply too shallow to accommodate a deepwater port. From a commercial and economic standpoint, water depth has always been the critical bottleneck constraining Macaursquo;s takeoff. Today, Mickey Hung combines Macaursquo;s unique feng shui and geographic setting to examine the conditions for constructing a deepwater port in the territory.I. Feng Shui LayoutFrom the perspective of traditional geographic feng shui, Macau sits on the western bank of the Pearl River estuary, with a classic ldquo;mountains embracing and waters encirclingrdquo; topography.bull; Water mouth and qi accumulation The three islandsmdash;the Macau Peninsula, Taipa, and Coloanemdash;are scattered like pearls, occupying a pivotal position at the Pearl River outlet. The currents from Modaomen and Lingdingyang converge here, forming a ldquo;crisscrossrdquo; pattern. Feng shui holds that ldquo;water follows the mountains, and qi follows the water.rdquo; As a zone where the Pearl River runoff and ocean tides contend, Macau is a natural ldquo;qigatheringrdquo; place.bull; Geographic advantage of KaHoacute; Village Coloanersquo;s KaHoacute; Container Terminal, located at Datan Point, is backed by hills and faces the open sea. In feng shui terms, this represents a stable ldquo;backed by mountains, facing waterrdquo; configuration. Unlike the Inner Harbour and the Outer Harbour, which are constrained by shoals and siltation, the KaHoacute; Container Terminal possesses a natural aura that ldquo;breathes in the oceanrsquo;s energy,rdquo; making it a vibrant site for Macaursquo;s new growth momentum.II. Topographic ConditionsThe surrounding topography poses natural challenges to deepwater port development, but solutions do exist.1. Natural depth limitationsMacau lies on the western side of the Pearl River estuary, precisely in the main area where riverine sediment spreads and deposits. As the current slows here and is further obstructed by tidal backwater, massive sedimentation occurs, resulting in significant siltation around Macaursquo;s waters. Port depths generally range only from 3 to 5 metres. Even the KaHoacute; Container Terminal, built after attempts to create a deepwater facility, reaches only 7ndash;9 metres and faces annual siltation of 38ndash;50 centimetres, with extremely high maintenance costs.bull; Inner Harbour and Outer Harbour Water depths are only 3ndash;4.5 metres, maintained mainly through frequent dredging, and can only accommodate vessels of around 1,000 tonnesmdash;far from sufficient for modern oceangoing shipping.bull; Shizimen Although certain local deep grooves reach 7 metres in depth, the strong backsiltation caused by sediment transport from the Maliuzhou waterway makes it an undesirable deepwater site.2. The ldquo;geographic advantagerdquo; of KaHoacute; Container TerminalThe KaHoacute; Container Terminal is widely regarded as the best port site in Macaumdash;and even in the western part of Lingdingyang.bull; High dredging efficiency The dredging volume required for a 10,000 tonne channel is only onethird of that for the Outer Harbour and onequarter of that for the Inner Harbour.bull; Controllable siltation The rate of backsiltation is far lower than at the Outer Harbour. Studies indicate that once throughput reaches a certain scale, the economic returns are sufficient to cover dredging costs, effectively breaking the ldquo;shallowwater constraint.rdquo;III. Hydrological ConditionsIn the Northern Hemisphere, because water flow consistently deflects to the right, two distinct types of riverbanks emergebull; Right bank erosional bank The current continuously scours the right bank, causing bank collapse and deepening of the riverbed. Thus, the right bank tends to have deeper water and steeper slopes, providing natural conditions for a deepwater port.bull; Left bank depositional bank The current carries eroded sediment to the left bank, where it settles. Hence, the left bank is typically shallow, gently sloping, and prone to siltationmdash;unsuitable for a deepwater port.NoteThe main stem of the Pearl River the Xijiang flows from northwest to southeast into Lingdingyang and the South China Sea. The direction of flow is northwest rarr; southeast.Standing at the Modaomen outlet, facing southeast toward the seabull; On your lefthand side geographic west Macau and Zhuhaimdash;the left bank of the Pearl River system, i.e., the depositional bank.bull; On your righthand side geographic east Hong Kong and Shenzhenmdash;the right bank of the Pearl River system, i.e., the erosional bank.Applying the Coriolis effect Northern Hemisphere currents deflect rightwardThe river flows southeastward and deflects to the right east, so the water force hits the eastern shore Hong Kong and Shenzhen, continuously eroding and deepening it. The sediment is separated and deposited on the western shore Macau and Zhuhai. This perfectly matches the theorybull; Right bank eastern shore ndash; Hong KongShenzhen erosion, deep water, natural good harbour.bull; Left bank western shore ndash; MacauZhuhai deposition, shoals, persistent siltation.IV. Comparative Waterway Advantages Macau vs. Hong KongFrom a feng shui perspective, Macau lies on the western side of the Pearl River estuary. The Earthrsquo;s rotation generates the Coriolis force, which deflects Northern Hemisphere currents to the right. Since the Pearl Riverrsquo;s main flow moves northwest to southeast into the sea, the rightward deflection shifts the current toward the west the Macau side. This western side receives about 95% of the riverrsquo;s sediment load, which, combined with lateral circulation, causes continuous sediment deposition near Macaursquo;s coast. As a result, extensive shoals and a westward‐biased sandbar have formed, leaving natural water depths severely inadequatemdash;making the site unsuitable for a large deepwater hub port.Hong Kong eastern side of the Pearl River estuaryHong Kong is located on the eastern side right bank of the estuary. Although the right bank is theoretically erosional, Hong Kongrsquo;s uniqueness lies in1. Geological advantage Victoria Harbour itself is a rock‐flooded valley, with a solid bedrock foundation that resists siltation.2. Strong hydrodynamics The sea areas around Hong Kong experience powerful currents that effectively carry away sediment.Thus, even though it sits on the ldquo;theoretically depositionalrdquo; side, Hong Kongmdash;thanks to its exceptional geological conditions and marine dynamicsmdash;has naturally become an excellent deepwater harbour.V. Feng Shui RecommendationsFor the development of a deepwater port in Macau, the following recommendations are proposedbull; Integrated planning and multipurpose works Combine deepwater port construction with land reclamation and airport projects. Employ artificial measures e.g., silt intercepting dikes to reduce back siltation, achieving multiple benefits such as wave protection, sediment control, and land utilisation.bull; Strengthen inland waterway connectivity Resolve the ldquo;bottleneckrdquo; at the Hongwan section of the Maliuzhou waterway, opening up the vital link between Macau and the Pearl Riverrsquo;s inland navigation network, thereby extending the portrsquo;s hinterland deep into the Pearl River basin.bull; Differentiated competition Rather than competing head on with Hong Kong or Gaolan Port, Macau should leverage its free port advantages to develop dedicated deep sea routes e.g., to Europe, positioning itself as an international hub within the Pearl River Delta port cluster.
