【摘要】：城市林業(yè)于20世紀60年代中期起源于北美洲,它是現(xiàn)代林業(yè)的一個重要分支,也是人類對環(huán)境危機積極思索的產(chǎn)物。城市是人類活動的一個主要區(qū)域,目前我國正處于城市化進程加速發(fā)展的階段,城市建設(shè)是影響國民經(jīng)濟和社會發(fā)展的重要因素之一。然而城市的快速發(fā)展也使人們不得不面對越來越嚴重的生態(tài)環(huán)境問題,城市林業(yè)體系建設(shè)是改善城市生態(tài)環(huán)境,實現(xiàn)城市可持續(xù)發(fā)展的重要舉措。 蘭州位于中國的西北地區(qū),是甘肅省省會城市,是甘肅省政治、經(jīng)濟、文化以及科教的中心,也是西北地區(qū)的中心城市及各大交通樞紐。經(jīng)過多年的發(fā)展,蘭州市取得了巨大發(fā)展,但是由于經(jīng)濟快速發(fā)展和城市化進程,蘭州市生態(tài)環(huán)境遭到破壞。蘭州市政府及市民高度重視城市生態(tài)建設(shè),并通過城市林業(yè)建設(shè)努力打造適宜的人居環(huán)境。經(jīng)過多年的努力,在城市林業(yè)建設(shè)上取得了一定的成績。但是還存在諸如全市生態(tài)環(huán)境仍然脆弱,森林資源總量不足、質(zhì)量偏低;資源增長較快,管理保護薄弱;科技創(chuàng)新不足,林業(yè)發(fā)展缺乏創(chuàng)新型支撐等問題。因此,本論文在相關(guān)理論的指導下,首先介紹了目前蘭州市城市林業(yè)現(xiàn)狀,在此基礎(chǔ)上深入剖析了蘭州市城市林業(yè)建設(shè)存在的問題及原因;其次,論文在借鑒國外發(fā)達國家城市林業(yè)建設(shè)經(jīng)驗的基礎(chǔ)上,提出蘭州市城市林業(yè)發(fā)展前景;最后,論文對蘭州市城市林業(yè)建設(shè)給出有針對性的對策建議。
[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.
