Table 3: Statistical table of reclamation projects in Hong Kong, 1980–1990 (incomplete statistics). known as the \"Rose Garden Project\") by the British Hong Kong Government in 1989, which enabled several major reclamation projects to be carried out, including the reclamation of 1248 hectares for the Chek Lap Kok Airport and 334 hectares for the West Kowloon area. These two projects' reclaimed area accounted for 79% of the total reclamation area in Hong Kong between 1980 and 1999; the reclamation projects significantly increased the area of land available for construction in Hong Kong. With several projects under the Programme being completed, such as the Chek Lap Kok Airport, the North Lantau Expressway, the Tsing Ma Bridge, and other important facilities, population and economic clusters have contributed to the development and prosperity of the third generation of new towns, represented by Tung Chung, comprising an integral part of Hong Kong's polycentric urban structure. The construction land area increased to 234.1 km\({}^{2}\) from 1997 to 2010, the growth rate remained between 1.94-3.12 km\({}^{2}\)-a\({}^{-1}\), and the expansion intensity was 1.22% (average value of 2000-2005 and 2005-2010). The growth area was mainly concentrated in Yuan Long, Tuen Mun, the North District, and other new towns. During this period, the new towns sprawled and connected to form regional new town clusters, gradually developing into the secondary city development axis of Hong Kong [44]. The \"Protection of the Harbour Ordinance\" was passed by the Legislative Council in 1997, and a large number of proposed reclamation projects could not be implemented. Some of the reclamation projects that have been carried out have used considerable construction land for high-density city expansion under harsh reclamation, such as the 290 hectares of reclamation for the Penny's Bay project (two phases combined) and the 127 hectares of reclamation for the Container Terminal No. 9 project. The rate of change in construction land in Hong Kong slowed down and remained between 0.17-0.26 km\({}^{2}\)-a\({}^{-1}\) from 2010 to 2020, with the intensity of expansion decreasing to 0.09% (average value of 2010-2015 and 2015-2020). Growth in construction land was mainly concentrated in the expansion of the third aircraft runway in the north of the Hong Kong Airport (estimated 650 ha of reclamation [45]) and the reclamation of the artificial island of the Hong Kong-Zhuhai-Macao Bridge Hong Kong Boundary Crossing Facilities (about 158 ha). The expansion of construction land in Hong Kong entered an extremely slow period under the constraints of the \" Protection of the Harbour Ordinance \" and the gradually emerging movement of ecological and environmental protection.
