【摘要】：近年来,随着景观生态学和可持续发展理论的普及,各城市开始大力发展生态建设,走可持续发展的道路。城市公园作为体现城市建设水平和精神文明面貌的窗口,其生态建设水平直接反映了城市的生态建设程度。对城市公园进行游憩景观生态适宜性评价,探索生态适宜性评价体系,分析公园内景观资源与游憩行为的适宜性程度,确定游憩景观与游憩行为的规划方向,是有效地进行城市公园生态化建设的重要途径,也合理进行城市公园景观生态规划的科学依据。本文以湖南烈士公园作为研究对象,在景观生态学的基础上,利用地理信息系统的空间分析和叠加技术,通过层次分析法和加权叠加法对湖南烈士公园游憩景观生态适宜性进行评价,并以评价结果作为公园生态规划的依据,提出合理利用公园游憩景观资源以及妥善规划游憩行为的建议。文章主要研究结果如下： (1)综合且系统地分析了国内外景观生态评价以及适宜性评价的起源与发展,总结了其存在的问题。阐述了地理信息系统技术在城市公园游憩景观生态适宜性评价研究中的优势所在,说明了进行游憩景观生态适宜性评价具有重要意义。 (2)简单陈述了目前广泛应用于景观生态评价和生态适宜性评价中的评价方法,并指出了各方法在实际运用中存在的不足。强调了景观生态适宜性评价在公园生态规划建设中的重要性,介绍了基于Arcgis的景观生态适宜性评价的方法,并在他人研究成果发现基于GIS的景观生态适宜性评价能够更加准确反映研究区域的生态环境状况,从更科学地指导公园景观生态规划,并依据评价结果提出合理的生态规划管理建议。 (3)通过对游憩景观自然度、游憩景观旷奥度、游憩景观相容度、游憩景观敏感度进行分析,并作为湖南烈士公园游憩景观生态适宜性评价标准,建立评价指标体系,生成各个评价指标分析图和生态适宜性评价图,并根据适宜性评价值对其进行分级,依据分级区域的适宜性状况对公园的景观生态规划提出建议。 (4)根据湖南烈士公园游憩景观生态适宜性综合评价值,将湖南烈士公园划分为四个适宜性等级区域,对适宜性较低的区域进行严格保护,对适宜性高的地区进行合理开发,指出公园内各个区域的目前存在的问题,并提出了解决措施,同时还提出了公园各适宜性区在景观生态规划以及游憩行为规划上的建议。总而言之,随着景观生态评价和规划研究的不断深入,近年来,GIS技术逐渐被应用于景观生态规划中,并取得了相当可观的成果。尝试将GIS技术运用于城市公园生态评价和规划中,作为城市公园生态建设的指导依据,也将成为一种必然的发展趋势。
[Abstract]:In recent years, with the popularization of landscape ecology and sustainable development theory, cities began to vigorously develop ecological construction and take the path of sustainable development. As a window to reflect the level of urban construction and the outlook of spiritual civilization, the ecological construction level of urban park directly reflects the degree of urban ecological construction. To evaluate the ecological suitability of recreational landscape in urban parks, to explore the evaluation system of ecological suitability, to analyze the suitability degree of landscape resources and recreation behavior in parks, and to determine the planning direction of recreation landscape and recreation behavior. It is an important way to carry on the ecological construction of urban park effectively, and the scientific basis of reasonable landscape ecological planning of urban park. This paper takes Hunan Martyrs Park as the research object, on the basis of landscape ecology, makes use of the spatial analysis and superposition technology of GIS. The ecological suitability of recreational landscape of Hunan Martyrs Park was evaluated by AHP and weighted superposition method, and the evaluation results were used as the basis of ecological planning of the park. Some suggestions on rational utilization of park recreation landscape resources and proper planning of recreation behavior are put forward. The main research results are as follows: (1) the origin and development of landscape ecological evaluation and suitability evaluation at home and abroad are analyzed synthetically and systematically, and the existing problems are summarized. This paper expounds the advantages of GIS technology in the ecological suitability evaluation of urban park recreation landscape. It is of great significance to evaluate the ecological suitability of recreation landscape. (2) the evaluation methods which are widely used in landscape ecological evaluation and ecological suitability evaluation are briefly stated. The shortcomings of each method in practical application are pointed out. The importance of landscape ecological suitability evaluation in park ecological planning and construction is emphasized, and the method of landscape ecological suitability evaluation based on Arcgis is introduced. It is found that the evaluation of landscape ecological suitability based on GIS can more accurately reflect the ecological environment of the study area and guide the park landscape ecological planning more scientifically. On the basis of the evaluation results, the authors put forward some reasonable suggestions for ecological planning and management. (3) by analyzing the natural degree of recreational landscape, the open degree of recreational landscape, the compatibility degree of recreational landscape, and the sensitivity of recreational landscape, the paper analyzed the ecological planning and management of recreation landscape. As the evaluation standard of ecological suitability of recreation landscape in Hunan Martyrs Park, the evaluation index system is established, and the analysis chart and ecological suitability evaluation chart of each evaluation index are generated, and the evaluation values are classified according to the suitability evaluation value. According to the suitable characters of the classified region, some suggestions were put forward for the landscape ecological planning of the park. (4) according to the comprehensive evaluation value of the recreation landscape ecological suitability of Hunan Martyrs Park, the martyrs park in Hunan was divided into four suitability grade regions. This paper strictly protects the area with low suitability, develops reasonably the area with high suitability, points out the existing problems in each area of the park, and puts forward some measures to solve the problem. Suggestions on landscape ecological planning and recreation behavior planning are also put forward. In a word, with the deepening of landscape ecological evaluation and planning, GIS technology has been gradually applied in landscape ecological planning in recent years, and considerable achievements have been made. This paper attempts to apply GIS technology to the ecological evaluation and planning of urban parks, as the guiding basis of ecological construction of urban parks, which will also become an inevitable trend of development.
