【摘要】：城市林业于20世纪60年代中期起源于北美洲,它是现代林业的一个重要分支,也是人类对环境危机积极思索的产物。城市是人类活动的一个主要区域,目前我国正处于城市化进程加速发展的阶段,城市建设是影响国民经济和社会发展的重要因素之一。然而城市的快速发展也使人们不得不面对越来越严重的生态环境问题,城市林业体系建设是改善城市生态环境,实现城市可持续发展的重要举措。兰州位于中国的西北地区,是甘肃省省会城市,是甘肃省政治、经济、文化以及科教的中心,也是西北地区的中心城市及各大交通枢纽。经过多年的发展,兰州市取得了巨大发展,但是由于经济快速发展和城市化进程,兰州市生态环境遭到破坏。兰州市政府及市民高度重视城市生态建设,并通过城市林业建设努力打造适宜的人居环境。经过多年的努力,在城市林业建设上取得了一定的成绩。但是还存在诸如全市生态环境仍然脆弱,森林资源总量不足、质量偏低;资源增长较快,管理保护薄弱;科技创新不足,林业发展缺乏创新型支撑等问题。因此,本论文在相关理论的指导下,首先介绍了目前兰州市城市林业现状,在此基础上深入剖析了兰州市城市林业建设存在的问题及原因;其次,论文在借鉴国外发达国家城市林业建设经验的基础上,提出兰州市城市林业发展前景;最后,论文对兰州市城市林业建设给出有针对性的对策建议。
[Abstract]:Urban forestry, which originated in North America in the middle of 1960s, is an important branch of modern forestry and a product of active human thinking about the environmental crisis. At present, China is in the stage of accelerating the development of urbanization. Urban construction is one of the important factors affecting the development of national economy and society. However, the rapid development of cities also makes people have to face more and more serious ecological and environmental problems. The construction of urban forestry system is an important measure to improve the urban ecological environment and realize the sustainable development of the city. Lanzhou, located in northwest China, is the capital city of Gansu Province. It is the political, economic, cultural, scientific and educational center of Gansu Province, as well as the center city and transportation hub of Northwest China. Lanzhou has made great progress, but as a result of rapid economic development and urbanization, the ecological environment of Lanzhou has been destroyed. The government and citizens of Lanzhou attach great importance to urban ecological construction. And through urban forestry construction efforts to create a suitable habitat environment. After years of efforts, in urban forestry construction has made certain achievements. But there are still some such as the city's ecological environment is still fragile, the total amount of forest resources is insufficient, The quality is on the low side; the resource growth is relatively fast, the management protection is weak; the science and technology innovation is insufficient, the forestry development lacks the innovation support and so on. Therefore, under the guidance of the related theory, this paper first introduces the present situation of Lanzhou city forestry. On this basis, the problems and causes of urban forestry construction in Lanzhou are deeply analyzed. Secondly, based on the experience of urban forestry construction in developed countries, the paper puts forward the prospect of urban forestry development in Lanzhou. The paper gives some countermeasures and suggestions to the urban forestry construction in Lanzhou.
