Draw a sketch map to show the land use of the area within easting 10 and 12; northing 78 and 80
10 12 80 Woodland Residential area Recreational area Industrial area Scale 1:20,000 78
Physical Constraint on expansion • Steep relief: • limited flatland • River channel: • restrict further reclamation • Country park/Nature reserve: • environmental conservation
Ways to Gain Land • Sea reclamation: • straight coastline • Leveling of hill slopes: • road cuttings at 1181, 1079 • Conversion of farmlands: • Cultivated land near Prince of Wales Hospital
Modification on Shing Mun River • straightened river channel: • straight shoreline • narrowed: • with reclamation • reduced and regular river discharge: • the building of the Shing Mun Reservoir
Modification on Shing Mun River • inflow of sea water: • reduced discharge • polluted river water: • industrial areas and residential areas
0678 lower drainage density flowing northwestwards dense vegetation cover flow into reservoirs protected within the country park no settlements less footpaths/less compaction no pylons/electric wire towers 0878 higher drainage density flowing southeastward sparsely vegetated flow across farmlands not within country park more settlements more footpaths/more compaction with pylons Drainage Pattern

Land Acquisition • leveling of slope because of presence of artificial slopes, proximity to foothill • Kam Ying Court(155822) • Saddle Ridge Garden(156824) • Reclamation because of proximity to coast, straight shoreline • Fok On Garden(145824) • Bay Shore Towers(150825)
Is Ma On Shan Self-contained ? • Ma On Shan is not much self-contained. • Residential accounts for the dominant land use (probably coupled with some retailing, small-scale commercial & recreational) • while other major land uses, such as industrial, business & large scale commercial are lacking. • Therefore there are not enough employment opportunities. • There are not enough social and public facilities, e.g. there is no hospital.
Human Impact on Stream Flow • Deforestation leads to the reduction of infiltration • Farming irrigation at Mau Ping(160780) and Mui Tsz Lam(152788) • Water for domestic uses by the villagers of the settlements (161799) • Mining activities(163801) • Construction of catchwater and water tunnel (grid square 1579)
Environmental Destruction • Soil erosion • Pollution of streams • Air and noise pollution • Affect channel flow because of • Deforestation • Quarry and cutting of slopes • Debris dumping • Transport of ores • Domestic wastes of the miners
Government Measures • incorporate it into Ma On Shan Country Park • change it into a cultural, historical recreational landmark • re-afforestation under the country park planning • restore scenic beauty • reduce soil erosion and pollution
