| The development of mankind has led to an increasing number of people living in cities rather than rural areas,and the level of urbanization in the world will be higher and higher,which makes the relationship between maintaining ecological balance and coordinating the relationship between mankind and nature more and more urgent.In this process,the urban heat island effect and the lack of green space and other issues have become increasingly prominent.China has been known as the "agricultural power" since ancient times,not only because it has a long farming civilization and a large number of agricultural population,but also has a vast area of arable land.However,in recent years,with the comprehensive improvement of the level of industrialization,the steady increase of the level of urbanization,the rapid expansion of the city led to the disappearance of agricultural land,the agricultural population is rapidly moving to the city,the transfer of rural population caused by the lack of agricultural labor Abandoned heavily.Towns continue to grow population will lead to rising food demand,while the rapid growth in demand for food at the same time,the domestic food supply is difficult to keep up with the pace of demand.Farming civilization is increasingly becoming a city residents desire natural,away from the hustle and bustle of psychological needs.Some cities are working to improve sustainability by improving urban green space and promoting urban agriculture.By building roof agriculture in urban agriculture,sustainable greening,social and economic development of urban buildings can be achieved.It not only helps to mitigate the environment Problem,but also to strengthen the city function and the development of urban food system.Urban roof crop landscape is based on the urban agriculture and roof greening of a crop to create the form of landscape,it as an effective way to promote the sustainable development of urban ecological landscape,by the international community’s attention.City roof crop landscape to meet the green roof of urban construction requirements,improve the city’s ecological environment,improve the city’s resource efficiency,enrich the city’s spiritual world.By studying the development process of urban agriculture,the development process of urban roof greening and the development process of urban roof agriculture,the definition and scope of urban roofing landscaping are obtained.Based on the study of the basic theory of roofing crops in modern cities,the study of relevant laws and regulations and the typical case studies at home and abroad,this paper puts forward the use of questionnaire to collect and analyze the public’s understanding degree,and through the beauty evaluation method,The landscape is forecasted and the landscape prediction model is established,and the most important factors affecting the beauty degree of crop landscaping are obtained.This paper analyzes the experimental results of the roof crops,analyzes the experimental results,sums up the lessons learned,and then combines the most important factors,theoretical research,case studies and experimental experience to influence the appearance of crop landscaping.The design of roof crops is proposed,and the development of urban roof crops So as to provide a scientific basis for the construction of sustainable development of the roof crop landscape. |
