Offshore wind power is an important kind of clean energy and of great development potential in the future. It has advantages of high wind speed and stable wind power, and gradually exhibits large‐scale, clustering, and long‐distance characteristics. Key technical problems of large‐capacity offshore wind power transmission over long distance must be solved in the development and utilization of offshore wind power, and will be addressed in this paper. First, this paper presents the overview of long‐distance offshore wind power integration in China, and then summarizes three types of integration schemes and its applicability. Second, it analyzes the characteristics of the voltage source converter based high voltage direct current (VSC‐HVDC) integration scheme and associated key technical problems in practice, and the first milestone long‐distance offshore wind power integration VSC‐HVDC project in China is then introduced. Finally, recommendations on long‐distance offshore wind power development in China are presented based on the characteristics of long‐distance offshore wind power and VSC‐HVDC integration technology.

Since the founding of the People’s Republic of China 70 years ago, the theory of urban green space system planning have been evolving along with the urbanization process. At the same time, it also draws nutrients from the planning thoughts of western developed countries. Under the background of ecological civilization construction, urban green space is more affected by the attention of the government and the public, urban green space system planning is the overall distribution of green space resources, reasonable construction of the important means of urban ecological environment, but the study of urban green space system planning evaluation has not yet been thoroughly. Urban green space system planning in China based on the development process and the landscape architecture of self-perfection for context, from the connotation of urban green space system planning evaluation, three aspects of theory and practice, combing summing up China’s urban green space system planning evaluation.
