Landscape Pattern Analysis And Spatial Optimization Of Urban Agriculture In Shen Fu New City

In recent years,urban development is very rapid,declining agricultural patches,based on the analysis of landscape pattern and ecological suitability of Shen Fu new town,to provide the necessary advice and reference for Urban Agriculture Planning,to realize the sustainable development of urban agriculture in Shen Fu new city,coordinating the development of urban agriculture and urbanization,reduce the impact of the villain for power,optimizing the function of urban agriculture and urbanization,the integration of urban agricultural landscape and urban landscape construction is of great significance.In this paper,the application of 3S Technology,based on the analysis of landscape pattern and ecological suitability of Shen Fu new town,the concept of urban agriculture was constructed,ecological control zoning,landscape planning,road traffic planning,etc..The results are as follows:(1)Landscape pattern analysis of Shen Fu new townBased on Arcgis technology,interpretation of satellite images in 2014 by the combination of computer classification and artificial classification,select different levels of landscape pattern index,through Fragstats software calculation and analysis.It can be concluded that:the number of patches in Shenyang City is relatively small,low fragmentation,the boundary characteristics of different patch types are relatively complex,the shape of the plaque is irregular,the key landscape types accounted for a large proportion of the overall landscape,energy and material migration between types are more open,the overall landscape diversity is high.(2)Ecological suitability analysis of Shen Fu new townIn this paper,from the perspective of natural ecology,the ecological suitability of the planning area is analyzed,according to the actual choice of the terrain,soil erosion,surface water,rain flood safety,vegetation cover,biological protection of the six elements,spatial distribution of six elements,according to the degree of correlation factors in the region,give them different weights,the use of GIS geographic information system for the calculation of the spatial function of the stack,the security pattern of natural ecological elements.(3)Urban planning of Shen Fu new cityUnder the premise of landscape pattern analysis and ecological suitability analysis,it is necessary to apply the theory of landscape design,taking into account the production,ecology.Based on the natural conditions,the development of social economy and the distribution of ecological control pattern,the urban agriculture structure of Shen Fu new city is a core two wing.To connect the three industry,the integration of three function as its basic characteristics,to form an internal hierarchical framework with rich content and cyclic development.
