| Lankao County is a county directly under the jurisdiction of Henan province and belongs to Kaifeng City.It is the birthplace of Jiao Yulu's spirit,a famous strategic pillar of the famous red cultural city and the Central Plains Economic Zone.However,due to frequent changes and frequent flooding in the Yellow River,natural disasters often occur in the region,and the ecological environment has been seriously affected.The green space is also constrained by natural environment and human interference,and the overall construction situation is lagging behind.In particular,there is a lack of systematic links between urban and rural greening.Although the layout of farmland and forest belts is more orderly and mechanism,the construction of systematic structure is not clear,the richness of green patches is low,the tree species is single,the ecological stability is poor,and the regulating ability of the surrounding ecosystem is weak.So the research on the landscape pattern of the area can better promote the construction of green space,improve its ecological environment,enhance the ability of anti disaster,and effectively improve the quality of the living environment of the residents in Lankao County.Landscape as a mosaic of a series of ecosystems or different land uses,there are many complex ecological processes within it.The research of landscape ecology is qualitative and quantitative analysis of the quantity,size,shape and distribution of basic landscape elements.From the perspective of landscape pattern,this paper makes use of GIS and Fragstats to analyze the characteristics of patch composition and spatial distribution of different green landscape,find the problems of the landscape spatial pattern,and combine the literature collection and field investigation to the detailed extraction and analysis of the green space in Lankao County.The construction and optimization of the landscape pattern pattern of harmonious and sustainable development in Lankao County.The main contents of this paper include the following aspects.The main contents of this paper are as follows:(1)introducing the method of green space information acquisition and processing,and drawing on the existing research at home and abroad,the landscape pattern analysis index of Lankao County is summarized and selected in detail.On this basis,the general methods and processes of landscape pattern analysis and optimization are summarized.(2)the present situation and characteristics of natural resources in the Yellow pan area of Lankao County were introduced in detail,and its ecological research value was analyzed,and the problems of green space construction in this area were found out.(3)taking Lankao County aviation image as the information source,combining the 3S technology to obtain different scales of landscape data,using the Fragstats software from the patch type and landscape level two angles,the landscape pattern of the county and urban area of Lankao County is analyzed.(4)combining with the natural characteristics of the yellow area of Eastern Henan and the content of landscape pattern analysis,the optimization principle of the landscape pattern of the county area of Lankao County is put forward,and the network construction model of Lankao County is designed,and the concrete optimization measures are put forward. |
