It has been 20 years since Wu Liangyong was inspired by 21 Agenda issued by UN Conference on Environment and Development in 1992, and first proposed sciences of human settlements in 1993. From 1993 to 2011, Wu Liangyong and his team had been devoted to theory research and practice of sciences of human settlements, hoping to form a system of it. In 2011, sciences of human settlements won the state supreme science and technology award. As a scholar with social responsibility and obligation, Wu Liangyong hoped that these scientific ideas can be carried out and practiced, and then be testified and improved. Thus, he revised several articles written in the last year and made them into a collection. These articles are based on theoretical discussions and aimed at exploring the developing direction of academic thinking. They are not merely contemplations in the ivory tower, but based on the Chinese reality and combined with information from many sources and practical projects.
