摘    要:采用景观格局指数及土地利用转移矩阵分析方法,研究从2000年至2018年惠州市土地利用景观格局特征及时空演变规律,并针对其景观生态发展突显的问题提出优化建议,为惠州市实现粤港澳大湾区生态担当的绿色城市定位提供规划参考。研究结果表明:(1)经历19年景观格局时空演变,惠州市土地利用类型丰富,其中林草地占景观总面积达64.21%,占据土地利用景观结构主导地位;(2)2000—2018年土地利用类型转化面积:未利用地>林草地>耕地>城乡工矿居民用地>水域,未利用地主要转化为林草地、耕地、城乡工矿居民用地而急剧减少,转化后三类用地面积显著增加,水域总体变化不明显;(3)惠州市2000—2018年各景观类型趋于均匀分布,存在多种优势种均衡发展。但与此同时城市化发展也导致其景观破碎化程度加剧,城镇用地边缘离散化,地类之间连接紧密性下降等问题出现。建议通过构建城市三生空间规划体系、生态廊道网络体系及优化城市发展空间布局等方式对惠州市景观格局进行生态优化。

关 键 词:景观格局  Fragstats  生态发展  格局优化

Abstract:Based on the landscape pattern index and land use transfer matrix analysis method, this paper studies the characteristics of land use landscape pattern and the space-time evolvement of Huizhou City from 2000 to 2018, and proposes optimization suggestions for the problems of landscape ecological development, it provides planning reference for Huizhou city to realize the green city positioning of Guangdong-HongKong-Macao Greater Bay Area. The results show that: (1) After 19 years of landscape pattern space-time evolvement, Huizhou has rich land use types, of which forest and grassland accounts for 64.21% of the total landscape area, occupying the dominant position of land use landscape structure; (2) Conversion of the land use types area in 2000-2018: unutilized land > forest and grassland > cultivated land > urban and rural industrial and mining residential land > water area, the unutilized land is mainly converted into forest and grassland, cultivated land, urban and rural industrial and mining residents" land, and the land area of ??the three types of land is significantly increased after conversion. The change of water area is not obvious; (3) The landscape types of Huizhou city tend to uniform distribution in 2000-2018, and there are balanced developments of various dominant species. At the same time, however, urbanization has also led to an increase in the fragmentation of landscapes, the discretization of urban land margins, and the decline in connectivity between land types. It is suggested to optimize the landscape pattern of Huizhou by constructing the urban production-living-ecology spatial planning system, the ecological corridor network system and optimizing the urban development spatial layout.
Keywords:landscape pattern      fragstats      ecological development      pattern optimization
