城景融合的新城景观生态网络规划——以河南省汤阴县绿色生态新城为例

THE ECOLOGICAL NETWORK PLANNING OF THE NEW TOWN IN REGARD TO THE INTEGRATION OF CITY AND LANDSCAPE: A CASE STUDY OF GREEN ECOLOGICAL NEW TOWN OF TANGYIN COUNTY, HENAN PROVINCE

随着城市化进程加快,生态网络规划已被广泛认可为一种协调城镇发展与环境保护间矛盾关系的有效手段。城市发展与生态基础设施的共轭性决定城市生态网络发展的一体性和有机性。本文以结构、功能为基础,立足社会生态系统和景观生态系统服务功能的提升来研究城市景观适应性系统。本文以河南省汤阴县为研究对象,为实现预设增效目标,提升服务功能,通过识别重要节点空间、廊道及关键性生态功能空间,构架不同等级生态廊道和景观斑块来修复城镇人居环境与自然生态系统,完善关键性生态功能空间的生态连接,强化城镇发展空间与外围生态建设空间的相互联系和生态连接,使网络化生态系统功能的功效最大化,进而构建城景交融、和谐共生的城市生态共同体。

With the acceleration of the urbanization,ecological network planning has been widely recognized as an effective means to coordinate the contradiction between urban development and environmental protection.The conjugation of urban development and ecological infrastructure is the deciding factor for the integrity and the organic characteristic of the development of urban ecological network.Based on the structure and function,this paper studies the urban landscape adaptability system aiming to improve the social ecosystem andthe landscape ecosystem service.This paper takes Tangyin County of Henan Province as the research object.In order to realize the prefixed targets and upgrade the function,it identifies important node space,corridors and key ecological function space,sets frames for different levels of ecological corridors and landscape patches to repair the urban living environment and the natural ecosystems.It improves the ecological connection of key function space,and strengthens the interaction and the ecological connection between the development space and the external ecological construction space,so as to maximize the function of the networked ecosystem,and then constructs an urban ecological community with the integration of urban and landscape and ecological symbiosis.
