The natural landscape main have Tian Zi Castle, Ji Ha Stockade, Tai Bai Rock; historical and cultural landscape main have Xi Shan Bell Tower, Bei Shan Temple,Mi Tuo Temple(there ever have Bai Yan Academy, Qing Yang Temple, Bell Tower and so on).
Character of Contrary Space Sequence Composition of Wanzhou area 2.1 Outer space composition analysis According to the principles of Contrary Space Sequence combinations, Wanzhou area at this stage of the external environment mainly in the peri-urban,including Tian Zi Castle, Ji Ha Stockade,Bei Shan Mountain, Tai Bai Rock,Cui Ping Mountain and other mountains landscape, as well as the Yangtze River, Tian Xian Lake external water landscape; and the Xi Shan Bell Tower, Mi Tuo Temple,and other artificial commanding point architectural landscape.
Outer Exchangeability Space -- City, Cui Ping Mountain, Tian Sheng Cheng park, Tai Bai Rock park and many other relatively high mountain form the Outer Exchangeability Space Skeleton, The line of sight permeat and naturl betwen mountain.
Gao Sun Tang square, Tian Sheng Cheng park, Tai Bai Rock park, such as the public square are Obstruct and Stay Space elements, Citizen square area is larger, the line of sight is broad, and with Bei Shan mountain, Tian Sheng Cheng park, Xi Shan Bell Tower form the line of sight exchange.
Landscape Visual Basic is completely separated, the whole square within buildings enclosing well type space, no sight passage and external connection, the previous Tian Sheng Cheng, Ji Ha Stockade, Yangtze River already vanished.
