【摘要】：伴随着工业化与城市化的快速发展,生态环境问题已成为城市发展过程中的一个十分重要的问题,如何协调发展以实现人与自然和谐共处已成为人类社会发展的必然选择。作为一种科学的城市发展模式,生态城市已成为理论界等各界共同关注的课题,生态城市的思想不仅为城市生态危机提供了解决思路,同时也为世界各国的决策者提供了新的发展理念。在我国已有160多个城市提出建设生态城市,相关的理论研究与实践探索也逐年增多。城市生态系统是生态城市概念提出的基础和依据。生态城市的发展目标是基于城市生态系统内部的作用机理所提出的城市系统发展模式。城市生态系统是一个由经济子系统、社会子系统及自然子系统构成的复合系统,其结构特征不仅与自然因素有关,而且与经济的发展和人类活动密不可分。因此,只有深入分析研究城市生态系统内部构成,各子系统内部影响因素的相互作用、系统与系统间的作用机理、同时探究系统外部影响因素对系统的影响,才能建立一个一般性的城市生态系统系统动力学仿真模型。用此模型来分析目标城市的城市生态系统问题,从而为生态城市相关政策的制定提供理论支撑与政策建议。本文的相关研究是围绕城市生态系统这一以人为中心和主体的,开放、复杂的系统展开。文章侧重于研究系统的构成及相互作用,作用机理、模拟仿真和实践方法。认为城市生态系统相关问题是一个动态非线性,并非单一静态的结果。本文建立并运用了城市生态系统的一般模型对哈尔滨市城市生态系统的实证研究,通过制定并对比经济增长型、生态发展型、人口控制型及均衡发展型4种类型6个具体方案的系统仿真结果,分析最适宜哈尔滨城市生态系统发展的发展路径,并提出经济、社会及自然三个方面相应的政策建议。从城市生态系统与生态城市概念的关系出发,提出更好建设生态城市的概念。
[Abstract]:With the rapid development of industrialization and urbanization, ecological environment has become a very important problem in the process of urban development. How to coordinate development to achieve harmonious coexistence between man and nature has become an inevitable choice for the development of human society. As a scientific mode of urban development, eco-city has become a common concern of the theoretical circle and other circles. The idea of eco-city not only provides a solution to the urban ecological crisis. At the same time, it also provides a new concept of development for decision-makers around the world. More than 160 cities in China have proposed the construction of ecological cities, and the related theoretical research and practical exploration are increasing year by year. Urban ecosystem is the foundation and basis of the concept of eco-city. The development goal of ecological city is the development mode of urban system based on the function mechanism of urban ecosystem. Urban ecosystem is a complex system composed of economic subsystem, social subsystem and natural subsystem. Its structural characteristics are not only related to natural factors, but also closely related to economic development and human activities. Therefore, it is only necessary to deeply analyze and study the internal composition of urban ecosystem, the interaction of influencing factors within subsystems, the mechanism of action between system and system, and at the same time, explore the influence of external factors of system on the system. Then a general simulation model of urban ecosystem dynamics can be established. This model is used to analyze the urban ecosystem problems of the target city, thus providing theoretical support and policy advice for the formulation of the relevant policies of the ecological city. This paper focuses on the urban ecosystem, a human-centered, open and complex system. This paper focuses on the structure and interaction of the system, the mechanism of action, simulation and practical methods. It is considered that the urban ecosystem related problem is a dynamic nonlinear, not a single static result. This paper establishes and applies the general model of urban ecosystem to the empirical study of Harbin urban ecosystem, through the formulation and comparison of economic growth, ecological development, The system simulation results of 6 concrete schemes of four types of population control and balanced development are analyzed, and the development path that is most suitable for the development of Harbin urban ecosystem is analyzed, and the corresponding policy suggestions in three aspects of economy, society and nature are put forward. Based on the relationship between urban ecosystem and the concept of eco-city, the concept of better construction of eco-city is put forward.
