Due to the topography and geographic range, slope and elevation, and direct solar radiation and sky diffuse difference, which make the load on the ground of the solar radiation varies from place to place. One of the most
important factors is the direction and height of slope . On the hill to the East and the west can effectively
block the sun (see Figure 1). Secondly, the slope surface and the sun angle difference influenced by solar radiation intensity, such as: with the sun light vertical slope surface to receive the maximum amount of radiation.
According to the relevant scholars, less harmful effects of wind slope to the valley 50 - 100 meters high. They
are generally located in low-lying areas, the sinking of cold air to form inversion layer, belonging to the Regional Greenhouse Environment better. Due to the cold plateau and cold pit, the top of the hill and slope valley has a
poor environment . The tall mountains formed a wet windward slope, leeward slope and small mountains
form a wet. In the air meet a tall hill, moist air concentration rises, air reaches the dew point in the windward
slope is the formation of cold climate. This makes the leeward drier caused the windward slope of wind and rain,
climate phenomenon and leeward slope dry wind . The small mountain is the opposite. Thus, there is the effect of air greenhouse environment on regional terrain elevation. Likewise, in the landscape space, the terrain
design can impact on the climate and environment space.
Undulating terrain can significantly change direction near earth atmospheric circulation, bound slope of the
temperature difference between hot and cold, forms the regional atmospheric circulation, thus affecting the urban wind environment. This forms the local terrain wind. Local terrain wind is regional climate impact phenomenon, the scale is about level less than 10 km, vertical 1 km. Valley wind usually occurs in the narrow and
steep valleys, with the cyclical nature of the diurnal cycle, which belongs to the special places of the wind.
Valley wind relatively mild, due to the air at night along the hillside down, to near surface cooling caused, effectively improve under the static wind city regional climate. Such as the geographical environment in some areas
surrounded by mountains, the summer villages dominated the wind are different from each other, but in the plain
area of law. Through the analysis of different terrain and improve the regional climate, and provide a theoretical
basis for the urban landscape design in landscape design in the urban landscape.
To sum up, from the macro level urban landscape of the urban environment, the impact of the urban environment is very important, the same terrain design on the micro level urban landscape space and the role cannot be
ignored. To a certain extent, the small terrain in the landscape space can be relatively free of change, so the feasibility of the improvement of the space climate is larger. In the design of terrain landscape space, we should
make full use of the transformation of the terrain or, in order to achieve the purpose of regulating the climate.
