{"title":"On the Sustainable Development of Forest Belt around Guiyang City","authors":"爽霏 钱","doi":"10.12677/wjf.2023.124029","DOIUrl":"https://doi.org/10.12677/wjf.2023.124029","url":null,"abstract":"Based on the development process of Guiyang ring forest belt construction, this paper discusses the process, scope and resources of Guiyang ring forest belt construction, and analyzes the effect of the ring forest belt construction on urban greening and ecological environment. Guiyang, as the capital of Guizhou Province and an important central city in Southwest China, has been committed to building a national demonstration city of ecological civilization in recent years. The construction of forest belt around the city is one of the important environmental protection projects. Since 1954, after several stages of construction, a two ring forest belt has initially formed, with a total length of 374 kilometers, covering 6 urban areas and 3 counties and cities of Guiyang City, with a total area of 2.184 million mu. In view of the existing problems of the forest belt around the city in Guiyang, this paper mainly discusses the key challenges of the construction of the forest belt around the city from the aspects of low forest quality, thin forest stand, single tree species, single structure, and monotonous forest morphology. Effective strategies and measures were put forward to achieve the precise improvement of Guiyang’s forest belt around the city. This includes restoration and optimization of diverse vegetation, rational planning and management of forest land, restoration and revitalization of degraded forest stands, and strengthening of ecological civilization education and publicity. Through the implementation of these strategies, we hope to comprehensively improve the ecological service function and ecological product supply capacity of the forest belt around the city, build the best demonstration urban forest system in the west, and build Guiyang into the goal of “a city of forests, a leisure resort” and a national colorful forest city. At the same time, this paper also lists the construction achievements of Guiyang’s ring forest belt, including greening a beautiful city, creating a cool city image, building a forest resort relying on the ring forest belt, attracting tourists and summer tourism, protecting the ecological environment, and taking the path of sustainable development. These achievements are strong proof of the construction of the forest belt around the city, and also the driving force and support for continuing to promote the project in the future. To sum up, Guiyang City Ring Forest Belt Forest Quality Precision Improvement Project is a comprehensive ecological environmental protection project, and its construction process, scope and resources have reference significance for other cities’ ecological civilization construction. Through effective strategies and measures, Guiyang is expected to become a model of national ecological civilization construction, providing valuable experience for future urban greening and ecological protection.","PeriodicalId":71691,"journal":{"name":"林业世界","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136201839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
