Air farm could provide urban people with a beautiful place to release working pressure,remove troubles,cultivate moral character and long for future.It was of practical value.The paper had analyzed the tendency and necessity to construct air farm and put forward limiting factors and favorable factors for construction of air farm.Limiting factors were:① man-made planting soil had separated plants from the earth,restricting the supply of underground water;② plants on roof had weak capacity resisting to wind.Favorable factors were fresh air,good light and large temperature difference between day and night,which were beneficial for growth of plants.Based on domestic planting of blueberry,starting from the angles of good visual appearance,ecological effect and economic effect,four planting methods of blueberry had been proposed,which were standard planting,landscape planting,greenhouse planting,and combination planting.It hoped to apply new techniques,new materials and research results in practical design of air farm as far as possible.
Significance of aromatic plants for the landscape construction on Hainan Island was analyzed from 3 perspectives:urgent needs of urban construction,therapeutic effects of plants,and economical efficiency,and 3 major characteristics of aromatic plants were summarized as:ornamental effects,aromatic properties and health care capacity.Application forms and ranges of aromatic plants in landscape design were introduced,and application principles were given as below:A."right species for right land",paying attention to the consistency between biological characteristics and environment;B.focusing on functions of plants,highlighting the harmony between plant landscapes and environment;C.in a relative high density,highlighting landscape layer of aromatic plants;D.proper combinations,highlighting primary fragrances.All of the above can be summarized as "right species for right land,focusing on plant functions,proper combinations,and targeted on landscape effects".The authors proposed that design modes of aromatic plant landscapes fit for Hailan Island should be refined to apply the theories of constructing aromatic city into the detailed planning.
