【摘要】：长株潭生态绿心处于长沙、株洲、湘潭三市交叉处地带,开发潜力较大,但由于本身承担着极为重要的生态功能,保护需求更大,因此保护与发展的矛盾突出,保护形势严峻。本研究以长株潭生态绿心株洲片区为研究对象,以景观结构与格局变化分析为切入点,以地理学、景观生态学、城市规划学、系统科学等学科理论为基础,借助ArcGIS、Fragstats、Yaahp等分析软件,分析景观结构动态变化和景观格局变化特征,划分景观功能区,构建景观功能评价指标体系和评价模型,并运用情景分析方法,研究不同情景下景观的格局特征及功能价值,明确景观功能调控方向,提出相应的景观功能调控方案措施。主要内容及结论包括:(1)通过遥感技术和ArcGIS空间叠加分析技术,得到研究区景观类型空间转移情况。结果表明,景观类型的转移以林地和耕地为主,建设用地面积小幅增加,草地、水域和未利用地均向林地、耕地和建设用地转移;(2)分别从景观类型和景观水平选取多项反映景观格局特征的景观格局指数,结果表明,研究区斑块类型的分布趋于离散,景观异质性程度较低,各景观类型斑块数量增加,林地、耕地和建设用地在2010-2014年破碎化程度加重;(3)将景观功能划分为生态保育功能、物质生产功能、经济发展功能三类,构建三个层次的景观功能评价指标体系,运用层次分析法确定指标权重,结合多目标线性加权函数法得到评价模型并计算评价结果;(4)依据不同土地利用情况设置了生态保护优先、产业发展主导和统筹协调发展情景三种情景,指出景观功能调控未来方向,从生态规划、生态工程和生态管理三方面分别提出调控措施及手段。
[Abstract]:Changsha Zhuzhou Xiangtan in Changsha eco green heart of Zhuzhou, Xiangtan, three city intersection area, the development potential of the larger, but because of itself undertakes extremely important ecological function protection, greater demand, so the contradiction between protection and development of the outstanding protection situation is grim. In this study, the Changsha Zhuzhou Xiangtan ecological green heart of Zhuzhou area the object of study, based on landscape structure and pattern change analysis as a starting point, based on geography, landscape ecology, city planning, based on system science theory by means of ArcGIS, Fragstats, Yaahp analysis software, analysis of the characteristics of landscape pattern changes and the dynamic changes of landscape structure, landscape division of functional areas, construction of landscape function evaluation index system and the evaluation model, and use the method of scene analysis, pattern characteristics under different scenarios of landscape and function of landscape function value, clear regulatory direction, put forward the corresponding landscape function regulation measures. Contents and conclusions include: (1) by remote sensing and ArcGIS spatial analysis technology, get landscape types research space transfer. The results show that the transfer of landscape types in the woodland and farmland, construction land area increased slightly, grassland, water area and uncultivated land to woodland, arable land transfer and construction; (2) from the landscape type and landscape level index to select a number of landscape pattern, landscape pattern characteristics. The results show that the distribution of patches in the study area type tends to be discrete, landscape heterogeneity degree is low, each type of landscape patch number increased, woodland, farmland and construction land increased in 2010-2014 years, the degree of fragmentation; (3) the landscape function is divided into ecological conservation function, material production function, economic development function of three kinds of construction, landscape function evaluation index system of three levels, using AHP to determine weights, Combined with the multi-objective linear weighting function method to obtain the evaluation model and calculate the evaluation results; (4) according to different land use set up ecological protection priority, leading industry development and coordinated development situation of three scenarios, pointed out the future direction of the landscape function regulation, ecological planning, put forward the control measures and means of three aspects of ecological engineering and ecological management respectively.
