【摘要】：生态单元制图是通过对区域遥感信息的解译及与现场调查信息的叠合,得到可视性较强的生态信息图谱,是将景观生态学成果应用到城乡规划中的一条有效途径。生态单元制图如何与中国城乡规划编制相衔接,提供专业、可靠的基础性研究成果,是本文期待解决的主要问题。提出了将城市所有用地类型都作为研究对象的"本土化"和"城市化"的生态单元分类方法,完成了符合我国《城市用地分类与建设用地标准》的生态单元制图分类系统(9大类37小类)及其景观生态学指数分析;通过绿地率、建筑密度、乔木树冠覆盖度、植物物种丰富度等各单项指标进行分层及叠加综合评价制图,科学全面地识别不同用地的生态价值。认为可以通过提出诸如各类城市用地的附属绿地的面积、容积率高低、建筑退让范围、大乔木的保护措施等具体细致的规划要求,来保护及调整城市用地内部的绿地面积及植被丰富度、乔木的覆盖度等生态指标,确保重要的城镇自然系统在城市开发过程中不受冲击,以及如何实现我国城市绿地的"精明增长"等后续研究方向。
[Abstract]:Ecological unit mapping (ECM) is based on the interpretation of regional remote sensing information and the superposition of field survey information to obtain a more visible ecological information map. It is an effective way to apply the achievements of landscape ecology to urban and rural planning. How to link ecological unit mapping with urban and rural planning in China provides professional and reliable basic research results. It is the main problem that this paper expects to solve. This paper puts forward the ecological unit classification method of "localization" and "urbanization", which take all the urban land types as the research object. The ecological unit mapping classification system, which conforms to the criteria of urban land classification and construction land in China, has been completed and its landscape ecology index analysis has been completed. Through the greenbelt rate, building density, tree crown coverage, plant species richness and other individual indicators to stratify and superposition comprehensive evaluation mapping. Scientific and comprehensive identification of the ecological value of different land use. It is considered that by proposing such as the area of all kinds of urban land attached to the green space, volume ratio, building concession scope. The protection measures of large trees and other specific planning requirements to protect and adjust the green space area and vegetation richness within the urban land, tree coverage and other ecological indicators. To ensure that the important urban natural system will not be impacted in the process of urban development, and how to realize the "smart growth" of urban green space in China.

【正文快照】： 我国城镇化水平的提高推动了经济社会的快速发展,但也造成了自然环境破坏、居住环境恶劣等一系列问题。城市规划学科的生态实效乏力使得新城的规模、职能和完备程度都距离规划设想相差较远[1],这在长三角显得尤为突出。快速城镇化造成了人类聚居地景观破碎化、生物多样性降低
