The scale of the landscape ecology research object is generally a few square kilometers to hundreds of square kilometers , 3S able to quickly access and process large amounts of spatial data , is the ideal means of landscape study , more and more applied to the field of landscape ecology . This study is based on the theory of landscape ecology , the use of \source data. Xinyang City, urban and rural ecotone landscape pattern, calculation and statistical landscape pattern index are as follows : fractal dimension : order a landscape types , construction land, agricultural land , forest and grassland , water and bare to take advantage of the multi - source data for 1.0892,1.1485,1.0826,1.0677,1.3241 ; landscape level fractal dimension of 1.3978 . Advantage : a landscape types were 1.7084,2.1056,2.0139,2.8232,1.4611 ; landscape level advantages of 0.9755 . Aggregation : a landscape types were 0.75251,0.85517,0.66209,0.87591,0.57269 ; landscape level aggregation 0.8700 . Separation: a landscape types were 0.0447,0.0479,0.0545,0.0482,0.0642 ; landscape level separation of 0.0494 . Fragmentation index : a landscape types were 0.05974,0.04875,0.01847,0.00316,0.07250 ; landscape -level fragmentation index of 0.04308 . The values of these indices typical watershed landscape and urban built landscape , focusing on the impact of urbanization on landscape fragmentation . According to the statistical results analysis , come to the preliminary conclusion of the study : the area landscape types unevenly distributed ; landscape patches to small or medium size ; relative rules of the economic landscape ; degree of landscape fragmentation . Recommendations focus on the development and protection of urban construction and environmental protection , in particular , Central South Bay area of Lake harmonious development .
