Evaluation And Improvement Of Urban Green Space Guided By Wilderness Thought

The Wilderness Act became the world’s first national law on wilderness protection,and the idea of wilderness protection has swept the globe.After more than 50 years of long development,the wilderness protection system is gradually perfected,the identification of wilderness areas is gradually accurate,and the quality of wilderness protection management is gradually improved.China has established many types of protected areas and the area of existing wilderness areas ranks sixth in the world.However,China’s protected area system lacks the type of wilderness and has not yet formed a systematic wilderness protection mechanism.The protection effect and management quality of the wilderness also need to be improved.Wilderness research in China is in its infancy,and there is still a long way to go to identify and evaluate wilderness areas and establish wilderness reserves.At present,for the establishment of wilderness indicators,each country or region has its own legislative guidelines,and with the continuous deepening of the research on the wilderness and the continuous improvement of the laws and regulations on wilderness protection,the indicators will also change as the wilderness activities unfold..This article is based on Tsinghua University’s Cao Yue,Yang Rui,and Long Ying published in 2017 "Research on the Identification and Spatial Distribution of Wildland in Mainland China".The state of research at home and abroad is expounded.Wilderness research in China is still in its infancy,but China’s wilderness research is urgent.In the second chapter,the background of the wilderness conservation movement is discussed,and the purpose,meaning,methods and research routes of the wilderness are expounded.In the third chapter,we have listed and summarized the wilderness evaluation studies in many countries,and analyzed the two evaluation methods currently used by the Wilderness Research Institute in China.In the fourth chapter,the ecological status of Xuancheng is The detailed analysis is combined with the indicators of wilderness degree evaluation,and the ecological network planning content of Xuancheng currently underway is discussed,and the ecological security assessment of Xuancheng green space is discussed,which lays a foundation for data and information for the subsequent wilderness degree evaluation of Xuancheng..In the Xuancheng Greenland Wilderness Evaluation in Chapter 5,in the exploration and practice of Xuancheng Greenland Wilderness Evaluation,the research method of the Chinese mainland-scale wilderness evaluation was adopted,four classic evaluation indicators were used,and the Boolean-WLC method was used.The Xuancheng Wilderness was evaluated and calculated again,and the two results were analyzed in combination with the content of China and Anhui Wilderness Evaluation.In the sixth chapter,combined with the results of Xuancheng greenland wilderness degree evaluation,different strategies of Xuancheng greenland wilderness degree improvement are discussed for Xuancheng greenland areas with different wilderness areas.Under the dual background of ecological civilization construction and rapid economic development and rapid urbanization,there are still many threats to the wilderness areas of great value.China’s wilderness research and conservation practices urgently need to be strengthened.
