The method and process of resistance breeding of two species of flower were introduced in the book. The distant hybridization was used for lodging-resistant breeding of Platycodon Grandiflorus and the lodging-resistant offspring were obtained. The results show that the lodging-resistant offspring could be the phenomena of apomixes which was induced by pollen. The Si-ion implantation mutation breeding was used for cold-resistant breeding of Oenothera speciosa and the cold-resistant offspring were obtained that can overwinter in Beijing. The results show that the cold-resistant character can be...

This book introduces a planning support system called Strategic Spatial Plan Support System (SSP-SS) to visualize population growth and predict energy demand, land use, and waste discharge resulting from urbanization. By analyzing policy interactions between household agents, the book uses SSP-SS to visualize policy effects on urban areas during stages of growth and decline. Simulations are created based on these policy outcome assessments, taking into account the influences of energy and resource consumption on sustainable development in urban environments. The book is geared towards...
