摘要
桂阳县自从在2009年成功创建了“国家园林县城”,便倡导建成区绿地系统进行提升和优化,其中公园绿地在绿地系统中占据重要地位,公园绿地的优化也成为重中之重。在此提倡之下,桂阳县着力打造宜居的生态环境,在巩固国家级园林县城成果的同时,以国家生态园林城市为风向标,着力打造“郴州市次中心城市”,于是对桂阳县绿地现状进行评估是必不可少的基础工作。城市化进程在发展中创造了巨大的财富,但是也严重破坏了城市中的生态环境。桂阳县在面对城市环境污染加重、资源束缚加剧、绿地生态环境系统逐步退化的严峻形势下,践行党的十八大做出“大力推进生态文明建设”的战略决策,树立尊重自然、顺应自然、保护自然的生态文明理念,走可持续发展道路。
桂阳县积极响应习近平在中央财经领导小组的第十二次会议上提出的对于建设城市绿化的主要内容:其一是要将城市中适合绿化的地方都进行绿化;其二是在建设公园上要保护生态系统的完整;其三是制定土地开发和保护的相关法律。公园绿地系统是城市系统中重要的一部分,是城市经济和社会可持续发展的基石,也是建设“生态城市”的重要生态基础设施。公园绿地水系等自然生态空间,是生态文明建设的核心要义,在中央省市大力推进生态文明建设的背景下,为保护好桂阳的山水生态环境,科学的布局桂阳生态空间,营造具有湘南地域特色的公园绿地生态系统。并通过将现代绿地系统规划的新理念、新方法的应用,努力打造具有桂阳特色的公园绿地系统,加快桂阳生态文明建设,建设美丽桂阳、幸福桂阳。基于此,本论文运用景观生态学、遥感理论等方面知识,理论联系实际,结合实地调查并依据前人的研究成果精华,在全面了解国内外生态园林城市的建设情况和评估手段,分析桂阳县建成区公园绿地建设现状,主要通过差距评估、标准评估和对比评估这三种评估方法,对桂阳县建成区公园绿地现状建设进行评估,为其建设生态园林城市提供切实、可行、科学的实践依据,主要的评估结果如下:
一是探明了桂阳县建成区公园绿地现状存在的问题,主要是绿地率、植物景观、养护管理等方面的问题;二是通过差距评估,得出了桂阳县建成区公园绿地现状与桂阳县公园绿地整体规划的差距;三是通过标准评估,得出了桂阳县建成区公园绿地现状与国家生态园林城市标准的差距,得出重点需要提质改造的公园;四是通过对比评估,得出了桂阳县建成区公园绿地现状与郴州市典型公园建设的差距,主要是景观性和养护管理方面的问题。

Abstract
Since Guiyang County successfully established the "Garden County of China" in 2009, it has advocated the promotion and optimization of the green space system in the built area, in which the park green space occupies an important position in the green space system, and the optimization of the park green space has also become the top priority. Under this advocacy, Guiyang County strives to create a livable ecological environment, consolidate the achievements of provincial garden county towns, and strive to create a national ecological garden city, Strive to create a "sub-central city of Chenzhou",so the evaluation of the current situation of Guiyang County is an essential basic work.The development of urbanization has created great wealth, but it has also destroyed the ecological environment in the city. Facing the severe situation of tight resource constraints, serious environmental pollution and ecosystem degradation, Guiyang County knows how to actively respond to the 18th CPC National Congress to make the strategic decision of "vigorously promoting the construction of ecological civilization". We must establish the concept of ecological civilization of respecting, conforming to and protecting nature, and take the road of sustainable development. It has become the goal pursued by the world in the new era that the environment is beautiful, the people are happy to live, and the development is stable. The sustainable development of the city must adhere to the road of ecological development. In this context, the advocacy of Guiyang County is worthy of recognition.
Guiyang County responded positively to the main contents of urban greening put forward by Xi Jinping at the 12th meeting of the Central Financial and Economic leading Group: the first is to afforest all the areas suitable for greening in the city; the second is to protect the integrity of the ecosystem in the construction of parks; and the third is to enact relevant laws on land development and protection. Park green space system is an important part of urban system, the cornerstone of urban economic and social sustainable development, and an important ecological infrastructure for the construction of "eco-city". The natural ecological space such as park green space and water system is the core of the construction of ecological civilization. under the background of vigorously promoting the construction of ecological civilization in central provinces and cities, in order to protect the landscape ecological environment of Guiyang and scientifically layout the ecological space of Guiyang, this evaluation is made to create a park green space ecosystem with regional characteristics in southern Hunan. And through the application of the new concepts and methods of modern green space system planning, we strive to create a park green space system with Guiyang characteristics, speed up the construction of ecological civilization in Guiyang, and build a beautiful and happy Guiyang. Based on this, this paper uses the knowledge of landscape ecology and remote sensing theory, combines theory with practice, combines field investigation and the quintessence of previous study results, and comprehensively understands the construction situation and evaluation means of ecological garden cities at home and abroad. this paper analyzes the current situation of park green space construction in Guiyang County, mainly through three evaluation methods: gap evaluation, standard evaluation and comparative evaluation.This paper evaluates the current situation of park green space construction in Guiyang County, so as to provide a practical, feasible and scientific practical basis for the construction of ecological garden city. The main evaluation results are as follows:
First, it finds out the problems existing in the current situation of park green space in the built-up area of Guiyang County, mainly in the aspects of green space rate, plant landscape, conservation and management, and so on. Second, through the gap assessment, it is concluded that the gap between the current situation of park green space in Guiyang County and the overall planning of park green space in Guiyang County. Third, through standard evaluation, the gap between the current situation of park green space in Guiyang County and the national ecological garden city standards is obtained, and the key parks that need to be upgraded and reconstructed are obtained. Fourth, through comparative evaluation, it is concluded that the gap between the current situation of park green space in Guiyang County and the construction of typical parks in Chenzhou is mainly the problems of landscape and conservation management.
