The construction of “four modernizations” eco-space is a vital starting point during the new round of development in Shanghai, creating additional technical challenges to urban green land planning. As a typical ecological space practicing harmonious coexistence between man and nature, the urban business district has tremendous significance for the applied research on the “four modernizations” concept in the city construction process. This article analyzed the development background and status problems in the construction of “four modernizations”, and the landscape connotations of “afforestation, colorization, preciousness and efficiency” applied in green space construction of urban business districts were interpreted from the aspects of ecology, identification, protect and openness. On this basis, combined with landscape construction in Shanghai Hongqiao business district, a four-point design strategy for the “four modernizations” concept applied in green space construction of urban business district was proposed taking objectives involving quantity increase of green space, quality improvement of colorization, retention of natural resources and function promotion of green space as breakthrough points. A typical application of landscape construction through strategies above in the Shanghai Hongqiao business district was summarized, intending to provide some practical reference for relevant theories and research improvement.
