【摘要】：绿地生态网络是以景观生态学和系统论为理论基础,以生态环境、生物物种多样性以及历史文化遗迹等的保护为目标,将生态网络与交通路网、河流水系、历史文化遗迹等进行结合,利用人为干涉进行生态系统重构的生态环境建设。在大力发展生态文明的今天,宁夏回族自治区固原市作为西北地区推进新型城镇化建设的试点之一,对于该地区的生态文明建设逐渐成为热议话题。固原市地处陕西、甘肃、宁夏三省首府城市的中心,占据交通要道,是宁夏回族自治区面向南部省份的门户,格外注重在环境与经济上的建设。固原市域范围内多是山区,南部六盘山的森林覆盖率超过百分之七十,具有较好的生态基础,但固原市中北部地区降水稀少,气候条件差,最主要的环境问题是该地区对土壤侵蚀较为敏感,即表现为水土流失、植被骤减。因此,将固原市作为西北地区城市绿地生态网络构建的实验基地,具有一定的实践价值。本文的主要研究内容包括:从固原市的生态环境演变入手,对当地的生态变化过程进行详细剖析,分析当今环境问题形成的原因,与此同时,研究绿地生态网络的构建目标即是保证生态系统的物质循环、保护生物多样性,分析论证得出只有绿地生态网络才是适合固原市的生态建设,并进行详细的固原绿地生态网络构建研究。论文成果如下:1.研究了固原市绿地的发展演变,得出该地区生态环境的变化趋势呈谷状分布,并分析当今存在环境问题的成因。2.分析固原市河流水系、人工绿地、交通网络与地形的分布规律,即市域范围内植被、水资源与灰色基础设施在形态上呈树状分枝,随山体走向而变化。3.提出绿地生态网络在水土流失地区构建的策略:鉴于固原市山地的地形限制,在空间层面上进行条带状扩展,分枝状连接地块上现有的绿地。4.绿地生态网络在欠发达地区的引导政策倾向,以教育引导为主,号召全民参与绿化建设,共同参与管理。
[Abstract]:The ecological network of green space is based on the theory of landscape ecology and system theory, with the aim of protecting ecological environment, biodiversity of biological species and historical and cultural relics, and combining ecological network with traffic network, river system, historical cultural relics and so on. To develop ecological civilization, Guyuan, the Ningxia Hui Autonomous Region, as one of the pilot projects to promote the construction of new urbanization in Northwest China, has gradually become a hot topic for the construction of ecological civilization in this area. The city of Guyuan is located in the center of Shaanxi, Gansu, and Ningxia, the capital city of the three provinces of Ningxia, which is the south of the Ningxia Hui Autonomous Region. The portal of the Ministry in the Ministry of the province attaches great importance to the construction of the environment and economy. In the area of Guyuan, the area of the six Panshan mountains is more than seventy percent in the South and has a good ecological base, but the precipitation in the middle and northern part of Guyuan is scarce and the climate is poor, and the most important environmental problem is that the area is more sensitive to soil erosion. Therefore, it is of practical value to take Guyuan as the experimental base for the construction of ecological network of urban green space in Northwest China. The main contents of this paper are as follows: starting with the ecological environment evolution of Guyuan, the process of local ecological transformation is analyzed in detail, and the environmental problems are analyzed. At the same time, the aim of the study of the ecological network of green space is to guarantee the material cycle of the ecosystem and protect the biodiversity. It is concluded that only the green ecological network is suitable for the ecological construction of Guyuan and the detailed construction of the ecological network in Guyuan. The results are as follows: 1. the study of Guyuan The development and evolution of urban green space shows that the change trend of ecological environment in this area is a valley distribution, and analysis of the causes of the existing environmental problems.2. analysis of Guyuan river water system, artificial green space, traffic network and terrain distribution law, that is, the vegetation in the city area, water resources and gray infrastructure in the form of tree like branches, along with the mountain Trend and change.3. put forward the strategy of building green land ecological network in soil erosion area: in view of the terrain limitation of Guyuan mountain area, the strip is extended in the spatial level, the existing green.4. green land ecological network in the branching connection land is guiding policy tendency in the less developed areas, guided mainly by education, and calls for the whole people to participate green. Build up and participate in management.
