Natural and Technical Conditions
|
Lies in area of low mountains and hills, elevation is between 90 and 116m, and the site is favorably even; airspace condition is sound, and so are construction geology and hydrogeology that meet requirements of recent use and long-term development of the airport.
|
Lies in area of low mountains and hills, elevation is between 80 and 130m, with relatively bigger difference, but the site is relatively complex; terminal airspace condition is sound, but earthwork treatment proves necessary to those extra-high hills; construction geology and hydrogeology are favorable, which meet requirements of recent use and long-term development of the airport.
|
Lies in area of low mountains and hills, elevation is between 91 and 115m, the site is relatively even, and terminal airspace condition is sound, but earthwork treatment proves necessary to those extra-high hills; side airspace allows to avoidance of ultra-high obstacles by Flight procedure design; construction geology and hydrogeology are favorable, which meet requirements of recent use and long-term development of the airport.
|
Houmentang Site’s airspace condition is more favorable.
|
Airspace Conditions
|
Meets requirements of Flight procedure design; airspace conflict with surrounding airports can be resolved by coordination.
|
Meets requirements of Flight procedure design; airspace conflict with surrounding airports can be resolved by coordination.
|
Straight-line distance of this site to Wuliyang Military Airport of Yushan Mountain is only 24km, airspace contradiction is outstanding with little possibility of satisfactory coordination.
|
Traffic Conditions
|
Entrance road can take use of the new national defence highway that is 4.5km away in the west, and a 5.0km-long entrance road needs to be paved.
|
Entrance road can take use of the 320 national highway that is 5.5km away in the north to reach the urban area, and a 7.0km-long special airport road needs to be paved.
|
Entrance road can take use of the 320 national highway that is 3.5km away in the east to reach the urban area, and a 4.5km-long special airport road needs to be paved.
|
Houmentang Site proves more convenient.
|
Supporting Facilities
|
Houmentang Site proves more convenient as to outside public facilities such as power, water, and gas supplies, drainage and communications. The other two sites are matchable in these regards.
|
Relocation Conditions
|
14 families in this site need to be relocated, and 110kv Maozao Line removed with expenses of 2.7 million RMB.
|
25 families in this site need to be relocated, and houses of 7500m2 need demolition with a cost of 3.4391 million RMB; the cable of Dong-Tuan 500kv and its matched 220kv cable to be built need to be redesigned, and the current 220kv II cable also needs to be removed. The total cost of relocation of high-tension cable is 2.7 million RMB.
|
20 families in this site need to be relocated, and houses of 9000m2 need to be undertaken demolition with a cost of 4.3243 million RMB; the existing Rao-Yu 110kv cable and Shang-Yu 220kv cable need to be removed with a total cost of 19.5 million RMB.
|
Houmentang Site requires less houses to be relocated.

Environment Influence Comparison and Selection
|
Noise Influence Comparison and Selection
|
Noise influence in the surrounding area of the airport ( sensitive points spread )
|
54 residential sensitive points and 15 school and hospital sensitive points (common villages and teams) spread within airport noise comparison scope.
|
30 residential sensitive points and unknown school and hospital sensitive points (common villages and teams) spread within airport noise comparison scope.
|
60 residential sensitive points and unknown school and hospital sensitive points (common villages and teams) spread within airport noise comparison scope.
|
Houmentang Site and Song Residence Site are matchable in noise sensitive degree, while Zhoujia Mountain proves best.
|
Running noise of the airport influences the planning area.
|
Extending line of central runway does not run over the urban planning area.
|
Extending line of central line in northeast of the runway runs over the urban planning area.
|
Extending line of central line in southwest of the runway runs over the urban planning area.
|
HExtending line of central runway of Houmentang Site
does not run over the urban planning area, allowing the least possibility of the plane flying over the urban area. Therefore, Houmentang Site is the best in this regard.

Ecological Impact Comparison and Selection
|
Earthwork Quantity
|
Total earthwork quantity of this project is 6,1600,000 m3, among which, excavation quantity is 3,170,000 m3, and filling quantity is 3,090,000 m3. No airspace clearance is required.
|
Excavation quantity is 480,000 m3, and filling quantity is 480,000 m3 (including airspace clearance).
|
Excavation quantity is 310,000 m3, and filling quantity is 310,000 m3; airspace clearance of earthwork quantity is 50,000 m3.
|
Zhoujia Site is the largest site.
|
Land Occupation
|
Land acquisition of 2,232 Mu (one unit of area in China ) covering mainly forest and farmland and including forest land of 1,473 Mu, dry land of 90 Mu and paddy field of 268 Mu.
|
Land acquisition of 3,000 Mu including forest land of 2,1574 Mu, dry land of 48.28 Mu, paddy field of 745.81 Mu, and water area of 48.51 Mu.
|
Land acquisition of 3,000 Mu including forest land of 766.65 Mu, dry land of 1,332.99 Mu, paddy field of 555.17 Mu, gardens of 51.51 Mu and water area of 159.96 Mu, plus undeveloped land of 46.99 Mu and residential land of 86.74 Mu.
|
Song Residence Site occupies the largest area of farmland.
|
Conclusion Comparison
|
Has moderate distance to the downtown area, and short distances to Sanqingshan Mountain and Wuruan Tourist Spot, favorable airspace conditions, less occupation of farmland, less earthwork and demolition quantities, and extending line of the runway does not run over the urban planning area. Supporting facilities are favorable.
|
Least occupation of farmland; complex geology with gullies in the middle that needs treatment; largest earthwork and demolition quantities.( especially the high-tension cable); relatively poor supporting facilities; less noise sensitive points spread in the surrounding area of the airport.
|
Has the shortest distances to Sanqingshan Mountain and Wuruan Tourist Spot; less earthwork and demolition quantities; largest occupation of farmland; difficult airspace coordination.
|
Houmentang Site serves as the proposed site with consideration of factors.
