【摘要】：長株潭生態(tài)綠心處于長沙、株洲、湘潭三市交叉處地帶,開發(fā)潛力較大,但由于本身承擔著極為重要的生態(tài)功能,保護需求更大,因此保護與發(fā)展的矛盾突出,保護形勢嚴峻。本研究以長株潭生態(tài)綠心株洲片區(qū)為研究對象,以景觀結構與格局變化分析為切入點,以地理學、景觀生態(tài)學、城市規(guī)劃學、系統(tǒng)科學等學科理論為基礎,借助ArcGIS、Fragstats、Yaahp等分析軟件,分析景觀結構動態(tài)變化和景觀格局變化特征,劃分景觀功能區(qū),構建景觀功能評價指標體系和評價模型,并運用情景分析方法,研究不同情景下景觀的格局特征及功能價值,明確景觀功能調(diào)控方向,提出相應的景觀功能調(diào)控方案措施。主要內(nèi)容及結論包括:(1)通過遙感技術和ArcGIS空間疊加分析技術,得到研究區(qū)景觀類型空間轉移情況。結果表明,景觀類型的轉移以林地和耕地為主,建設用地面積小幅增加,草地、水域和未利用地均向林地、耕地和建設用地轉移;(2)分別從景觀類型和景觀水平選取多項反映景觀格局特征的景觀格局指數(shù),結果表明,研究區(qū)斑塊類型的分布趨于離散,景觀異質(zhì)性程度較低,各景觀類型斑塊數(shù)量增加,林地、耕地和建設用地在2010-2014年破碎化程度加重;(3)將景觀功能劃分為生態(tài)保育功能、物質(zhì)生產(chǎn)功能、經(jīng)濟發(fā)展功能三類,構建三個層次的景觀功能評價指標體系,運用層次分析法確定指標權重,結合多目標線性加權函數(shù)法得到評價模型并計算評價結果;(4)依據(jù)不同土地利用情況設置了生態(tài)保護優(yōu)先、產(chǎn)業(yè)發(fā)展主導和統(tǒng)籌協(xié)調(diào)發(fā)展情景三種情景,指出景觀功能調(diào)控未來方向,從生態(tài)規(guī)劃、生態(tài)工程和生態(tài)管理三方面分別提出調(diào)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.
