【摘要】：随着我国社会经济的发展与生态自我意识的觉醒,城镇化与生态文明建设成为当今社会关注的热点。城镇生态监测与评价是新型城镇化建设的重要基础,而高分影像解译技术的发展为之提供了可能。本文在综合现有研究的基础上,开展城镇生态利用评价体系和生态利用信息提取方法研究。首先确定城镇宗地生态利用评价的内涵、研究对象和研究尺度,确定城镇宗地生态利用相关概念、生态利用评价的定义及研究内容,建立基于遥感的生态利用评价指标体系。接下来,以宁夏平罗县城为例,重点研究了生态利用信息的遥感提取技术,主要包括:(1)基于实地监测完成单位面积生物量测算;(2)基于绿地解译方法完成绿化覆盖率测算;(3)基于回归模型完成盖度、叶面积指数提取;(4)基于特征筛选方法完成建筑面积提取。在上述研究的基础上,结合实地调查数据探讨了城镇宗地生态利用评价体系,并以平罗县城为例开展实证研究,主要包括:(1)提出了基于特征分析法和模糊综合评判方法的城镇宗地生态利用现状评价体系;(2)提出基于现状潜力和规划潜力两个角度研究生态利用潜力的评价方法;(3)应用数理统计分析、空间分析、地统计分析等方法对各评价结果进行分析。评价结果表明:(1)基于遥感的城镇地理信息提取方法能够较好的满足生态利用评价的需要,能够在保证较高精度的基础上有效进行城镇地物解译;(2)几种生态利用评价方法能够较为客观地反映城镇生态利用情况,现状评价和潜力评价的研究方法分别为城镇生态建设中基础数据获取方法提供了研究思路。
[Abstract]:With the development of social economy and the awakening of ecological self-consciousness, urbanization and ecological civilization construction have become the focus of attention. Urban ecological monitoring and evaluation is an important basis for the construction of new urbanization, and the development of high score image interpretation technology provides the possibility. Based on the existing research, this paper studies the evaluation system of urban ecological utilization and the method of extracting ecological utilization information. Firstly, the connotation, research object and research scale of ecological utilization evaluation of urban parcels are determined, and the related concepts, definitions and contents of ecological utilization evaluation of urban parcels are determined, and the evaluation index system of ecological utilization based on remote sensing is established. Next, taking the city of Pingluo County in Ningxia as an example, it focuses on the remote sensing extraction technology of ecological utilization information. It mainly includes: 1) based on field monitoring to complete biomass measurement of unit area. 2) based on greenbelt interpretation method to complete green coverage calculation. (3) based on regression model to complete coverage, leaf area index extraction to complete building area extraction based on feature selection method. On the basis of the above research, combined with the field investigation data, this paper discusses the evaluation system of ecological utilization of urban parcels, and takes Pingluo County as an example to carry out an empirical study. This paper puts forward the evaluation system of ecological utilization status of urban parcels based on characteristic analysis and fuzzy comprehensive evaluation.) it puts forward an evaluation method to study ecological utilization potential based on present situation potential and planning potential. Application of mathematical statistical analysis, Spatial analysis, geostatistical analysis and other methods to analyze the evaluation results. The evaluation results show that the method of extracting urban geographic information based on remote sensing can better meet the needs of ecological utilization evaluation. Several ecological utilization evaluation methods can objectively reflect the situation of urban ecological utilization on the basis of ensuring high accuracy. The research methods of present situation evaluation and potential evaluation provide the research ideas for the basic data acquisition methods in urban ecological construction.
