【摘要】：近年来,城市发展十分迅速,农业斑块不断减少,本文通过对沈抚新城的景观格局和生态适宜性进行分析和探索,为此区域的都市农业空间布局提供依据,对沈抚新城的都市农业进行优化,协调都市农业发展和城市化、减小人为力量的冲击、优化都市农业功能与城市化、将都市农业景观和城市景观建设融为一体具有重要的意义。本论文里通过3S技术,对沈抚新城研究区进行景观格局分析与生态适宜性分析,并以此为依据优化构建了都市农业功能分区,探讨了生态控制分区、景观景点策划、道路交通规划等。研究结果如下:(1)沈抚新城的景观格局分析通过计算机的ArcGis软件解译沈抚新城2014年的卫星影像图,并通过Fragstats软件计算景观格局指数,分析结果如下:沈抚新城的斑块数目相对很少,破碎度低,不同斑块种类的边界特征相对复杂,斑块的形状也不规则,在景观整体中关键景观类型的比重很高,类型之间的能量和物质移动畅达,整体景观的多样性很高。(2)沈抚新城的生态适宜性分析本文里主要从自然的角度来对研究区进行生态适宜性分析,根据实际选择了地形地貌、土壤侵蚀、地表水源、雨洪安全、植被覆盖、生物保护六个要素,绘制六个要素因子的空间分级图,按照相关因子在区域内的重要程度,给予它们不同权值,利用GIS地理信息系统的空间运算功能进行因子堆叠,构建自然生态要素的安全格局。(3)沈抚新城的都市农业优化在沈抚新城景观格局及生态适宜性分析的基础上,综合借鉴景观设计学理论,又要兼顾都市农业的发展模式。结合自然条件、社会经济发展的现状、生态控制格局分布,沈抚新城的都市农业空间布局为一核两翼一带。以"连接三产,融合三生"为主要发展策略,在生态保护的基础上形成沈抚新城都市农业的空间优化。
[Abstract]:In recent years, the urban development is very fast, the agricultural patch is decreasing continuously. This paper analyzes and explores the landscape pattern and ecological suitability of Shenfu New City, and provides the basis for the spatial layout of urban agriculture in this area.It is of great significance to optimize the urban agriculture of Shenfu New City, coordinate the development of urban agriculture and urbanization, reduce the impact of artificial forces, optimize the function of urban agriculture and urbanization, and integrate the urban agricultural landscape and urban landscape construction.In this paper, through 3s technology, the landscape pattern and ecological suitability of Shenfu Xincheng research area are analyzed, based on which the urban agricultural function zoning is optimized, and ecological control zoning and landscape scenic spot planning are discussed.Road traffic planning, etc.The results of the study are as follows: 1) the landscape pattern of Shen Fu Xincheng is analyzed. The satellite image of Shenfu Xincheng in 2014 is interpreted by computer ArcGis software, and the landscape pattern index is calculated by Fragstats software.The results are as follows: the number of patches in Shenfu New Town is relatively small, the degree of fragmentation is low, the boundary characteristics of different patches are relatively complex, the shape of patches is irregular, and the proportion of key landscape types in the whole landscape is very high.The ecological suitability of Shenfu Xincheng is analyzed mainly from the natural point of view, and the topography and landform are selected according to the actual situation.Soil erosion, surface water sources, rain and flood safety, vegetation cover, biological protection, spatial classification of the six factor factors, giving them different weights according to the importance of the relevant factors in the region,On the basis of the analysis of landscape pattern and ecological suitability of Shenfu New Town, the security pattern of natural ecological elements was constructed by using the spatial operation function of GIS to build up the security pattern of natural ecological elements, and the urban agricultural optimization of Shenfu New Town was based on the analysis of landscape pattern and ecological suitability of Shenfu New Town.Comprehensive reference landscape design theory, but also to take into account the development model of urban agriculture.According to the natural conditions, the present situation of social and economic development, the distribution of ecological control pattern, the spatial distribution of urban agriculture in Shenfu Xincheng is one core and two wings.Based on the main development strategy of "connecting the three industries and integrating the three generations", the spatial optimization of urban agriculture in Shenfu Xincheng was formed on the basis of ecological protection.
