Research On The Optimization Of Landscape Pattern Of Tuanjie Town Based On GIS And Fragstats

Since the reform and opening up, China is being promoted the socio-economic development of the high-speed with a period of rapid urbanization, which inevitably lead to changes in the urban landscape pattern and ecological processes, result in a series of ecological and socio-economic consequences and seriously affect further development of the city. From the perspective of Landscape ecology, issues faced by the cities include environmental pollution, ecological destruction and problems such as traffic jams, heat island effect, mostly due to the discordance of the composition of urban landscape, unreasonable structure and pattern, landscape elements in such aspects as structure, function and spatial relationship. Therefore, the study of small town landscape structure and ecological function characteristics is very important which can reveal mechanisms an laws of the landscape succession, and at the same time predict the evolution trend of urban complex ecosystem, and establish the sustainable urban development model.From the perspective of landscape ecology, by comparing the different characteristics and their variations, etc.of the landscape patches, to study the problems of the landscape spatial pattern and spatial configuration consisting relationship.In the process of landscape spatial pattern analysis,based on the town land use data, first land use maps are reclassified for the principles of landscape classification through GIS, generate solidarity town landscape patch type map. Then landscape spatial structure of the town is analyzed quantificationally by Fragstats, and summed the problems and their causes of the landscape spatial pattern through the quantitative data.Finally, base on ecological sensitivity and ecological suitability evaluation of analysis results, ecological functions of the town is analyzed, combined with finishing land types on the overall plan of the town and adjusting industrial layout features, uniting the town planning of landscape ecological functions and landscape space design, the spatial pattern of land use, natural environment and economic development of the region in harmony to achieve unity town landscape spatial pattern optimization goals.
