【摘要】：气候变化是目前人类面临最具挑战的环境问题,随着城镇化的加快中国大气中CO2正快速上升,国际能源机构(IEA)的研究报告表明中国已经超过美国成为碳排放第一大国。城市是人类主要聚集地,是全球气候变化反应敏感的区域之一。全球城市化进程对全球温室气体排放有着显著影响。城市实现低碳发展最重要的一步就是低碳规划,生态城市建设则是实现低碳城市(Low-carbon City)目标的重要途径。随着城市化进程的加快以及人口增长和经济发展,沈阳市沈北新区正经历着中心城区持续持续扩张,基本农田大量流失,区域自然景观日趋破碎化的变化之中。利用地理信息系统(GIS)对沈北新区的城市土地利用变化特征进行深入分析,并在此基础上依据低碳目标对城市生态格局进行模拟与重建,最后提出了沈北新区低碳空间的规划策略。本论文取得如下研究成果：(1)沈阳市沈北新区城市面积持续增加,城市化进程正在显著加速,城市向外扩张强度逐渐增强。三环北侧是城市增长的主方向,蒲河新城及周边(8～10km)各级经济开发区是增长的热点区域。(2)沈北新区土地利用变化最主要的特征是耕地向城乡建设用地的大面积转换。持续的城市增长导致区域景观日益破碎化和复杂化。城市和其它建设用地的景观影响日益增强,耕地的优势地位减弱。城市化空间梯度上的土地利用格局变化分析表明,随着城市化水平的提高,景观组成和空间配置发生了明显变化。处在城市化前沿区域的城郊地区,景观格局表现出景观多样性增加、破碎化程度加深和形状日趋复杂等特点。通过土地利用得出城市碳源碳汇空间分布格局,计算了碳平衡的差值。(3)本文论述了低碳城市及其规划研究背景和相关研究的现状进展,以构建适合中国国情的低碳城市规划研究的理论框架为出发点,揭示低碳城市空间布局、城市碳汇空间规划及城市低碳交通规划方法,初步探讨低碳城市规划模式研究相关领域(4)以沈北新区为例研究了城市碳源碳汇结构与布局影响因素,提出了低碳城市规划的策略,运用低碳城市规划理念和规划模式方法对沈北新区低碳城市规划进行实例研究和提出规划策略。
[Abstract]:Climate change is the most challenging environmental problem facing mankind at present. With the acceleration of urbanization, the CO2 in the atmosphere of China is rising rapidly. A report by the International Energy Agency (IEA) shows that China has surpassed the United States to become the largest country in carbon emissions. Cities are the main gathering places for human beings and one of the sensitive regions for global climate change response. Global urbanization has a significant impact on global greenhouse gas emissions. Low-carbon planning is the most important step in the development of low-carbon cities, and the construction of eco-cities is an important way to achieve the goal of low-carbon cities. With the acceleration of urbanization, population growth and economic development, Shenyang Shenyang North New District is undergoing a sustained expansion of the central urban area, a large number of basic farmland loss, the regional natural landscape is becoming increasingly fragmented changes. The characteristics of urban land use change in Shenbei New area were analyzed by using GIS, and the urban ecological pattern was simulated and reconstructed according to the low carbon target. Finally, the planning strategy of low carbon space in Shenbei New area is put forward. In this paper, the following research results are obtained: (1) the urban area of Shenyang Shenyang New District is increasing, the urbanization process is accelerating significantly, and the intensity of urban outward expansion is gradually increasing. The north side of the third Ring Road is the main direction of urban growth, and the Puhe New City and its surrounding economic development zones at all levels are the hotspots of growth. 2) the most important feature of the land use change in Shenbei New area is the large area conversion of cultivated land to urban and rural construction land. Sustained urban growth has led to the growing fragmentation and complexity of regional landscapes. The landscape influence of urban and other construction land is increasing day by day, and the dominant position of cultivated land is weakened. The change of land use pattern on the spatial gradient of urbanization shows that the landscape composition and spatial allocation have changed obviously with the increase of urbanization level. The landscape pattern in the suburban areas in the front of urbanization shows the characteristics of increasing landscape diversity, deepening fragmentation and increasingly complex shape and so on. Through land use, the spatial distribution pattern of urban carbon sink and the difference of carbon balance are calculated.) in this paper, the background of low-carbon city and its planning and research background and the status quo of related research are discussed. Based on the construction of a theoretical framework of low-carbon city planning suitable for China's national conditions, this paper reveals the spatial layout of low-carbon cities, urban carbon sink spatial planning and urban low-carbon transportation planning methods. Taking Shenbei New area as an example, this paper studies the influence factors of carbon sink structure and layout of urban carbon source, and puts forward the strategy of low carbon city planning. A case study on the planning of low-carbon cities in Shenbei New District is carried out by using the concept of low-carbon city planning and the planning model method, and the planning strategies are put forward.
